    - ComboBox design-time DataBinding setting questions. These setting mystify me for these reasons. *SelectedItem* - Help says that 'SelectedItem' gets or sets the currently selected item in the combobox. *SelectedValue* - Help says that 'SelectedValue' gets or sets the value of the member property specified by the ValueMember property. *ValueMember* - Help says that the 'ValueMember' Gets or sets the property to use as the actual value for the items in the ListControl. The above three properties are described as results of runtime events! What are they doing in the properties section of the ComboBox????? How do I use them to sync a databound combobox on a form with the current bound row on the form? Please help me understand how to use these settings? Thank you, dbuchanan Tag: DataGridView automatically selects first row Tag: 97159

    - maximized MDI Child position shifts Hi. I'm using VS2005, Framwork 2.0. I have an MDI app. The child forms are maximized within the parent. The child forms have the controlbox property set to false and the text property is empty. When my child form opens, the top 40 pixels or so get covered up by the parent. It seems that the child form is shifted up. So I changed my child form so that all controls are shifted 40 pixels down, leaving 40 pixels of empty space at the top. When I do this, the child form shows up correctly as the empty space gets covered up rather than my controls. But once and a while (I haven't found the pattern yet) the child form will shift back down that 40 pixels leaving me with blank space up top and covered controls down below. Has anyone else seen this behavior? I have noticed that if I put a value in for the text property of the child form, I don't have to shift my controls down 40 pixels and I don't get the random shifting. But the parent form takes this child text property and appends it to it's own text property in brackets. Mabye the answer is to put something in the child text property and somehow override how the parent writes it's text property? Can someone help me on how to do this? Thanks in advance.

    - Dll Reference Performance Are there any performance issues, if we have many dll reference added to our project. Any way, does it take more time to load the application if we have many dll reference added to a project, even though we don't use at application load. Does more dll takes more time to load. If we merge many dll into one does it improve the performance. Our application takes long time to load, and we are doing nothing at startup. We are using "no touch deployment". Please suggest any way to load the application faster. Any help greatly appreciated. Dan Tag: DataGridView automatically selects first row Tag: 97155

    - Making a Winforms app behave like a Console app I am attempting to add a "console mode" to my Winforms app. My intention is that when I start the app with a special switch (for example "myapp.exe /batch") to does not launch a graphical UI but instead just displays console messages. My first guess was to simply change the Main method of the startup class to do something like this... if (batchMode) { Console.WriteLine("Now in batch mode"); ... } else { MainForm.Run(); // Launch graphical user interface } Unfortunately, it looks like my app does not behave like a real console mode app in either case. When I execute the app from the command line, the app returns immediately and text output by Console.Write() does not appear anywhere. Setting the app as a Console mode application does not give me what I want either. With this mode, a big black console output box appears even when in "GUI mode". Is there a way to build one executable that supports both modes and dynamically switches at runtime? Tag: DataGridView automatically selects first row Tag: 97151

    - Sync databound combobox to current bound record in form VS2005 I've been reading all the help I can on the topic (MSDN, other) but I can't make sense of this. Desired behavior; The user is to choose from the displayed list of the databound combobox and the coresponding 'Id' from the lookup table is to be inserted into the field of the new record. I have two simple tables. "tblPerson" is the data table. The lookup table is "lkpPersonType". The combobox dropdownstyle is "dropdownlist" to limit the user to the list. Here are the two tables "tblPerson" Id int IDENTITY (1, 1) NOT NULL , Name varchar(50), Address varchar(50), fkPersonTypeId smallint "lkpPersonType" pkPersonTypeId smallint IDENTITY (1, 1) NOT NULL , Type varchar(50) NOT NULL , The form has two binding sources "TblPersonBindingSource" for the data table and "lkpPersonTypeBindingSource" for the lookup table. The Display Member of the combobox is the "Type" field and the value member is "pkPersonTypeId" field. The Text property of the combobox is set to the "fkPersonTypeId" of the table "tblPerson". The next parts I am unsure of... I did not set the Selected Value (???) I set the Selected Item to the "Type" field of the lookup table lkpPersonType When I run the app the combobox populates. The data seems to display properly for the first record, but the combobox does not cycle through the values I know are assigned to it for the other records. In other words it is not properly bound. However there is a relationship between the two tables in the dataset, but the relationship is not specifically refered to in the form. Here is my code in the load event; \\ Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.TblPersonTableAdapter.Fill(Me.DataSet1.tblPerson) Me.LkpPersonTypeTableAdapter.Fill(Me.DataSet1.lkpPersonType) Me.FkPersonTypeIdComboBox.DataSource = Me.lkpPersonTypeBindingSource Me.FkPersonTypeIdComboBox.DisplayMember = "Type" Me.FkPersonTypeIdComboBox.ValueMember = "pkPersonTypeId" 'Me.FkPersonTypeIdComboBox.SelectedValue = ??? 'Me.FkPersonTypeIdComboBox.SelectedItem = "Type" Me.FkPersonTypeIdComboBox.Text = "TblPersonBindingSource.fkPersonTypeId" End Sub // Please help me make some sense of this and get it working.

    - How can I find BindingSource has some changed data. Hi, In my WinForms application, I have a set of controls that are bound to a BindingSource control. When the user closes the form, I need to ask him if he wants to save data. The problem is I cannot find anyway to check if the value of any textboxes is changed! Obviously checking DataSet.HasChange is not adequate. The reason is that the user might be in middle of adding or editing a record so the record has not been reflected to underlying dataset yet, but user accidentally clicks on form close button. Any help would be appreciated, Alan Tag: DataGridView automatically selects first row Tag: 97142

    - MDI Child Forms -- Diffrent Behavior in new Framework I have an exsiting MDI application. I have the when the child is called from the Parent, I set it's DockStyle to fill, I also have the child form set to maximized In VS 2003 and 1.1 this works the way I want it to, the child form is maximized whithin the parent so that a title bar is not displayed nor is a window border, it looks like it's a panel in the parent form. In VS 2005 and 2.0 it will not draw this way, no matter what I set the window size property to, the child still draws as a window within the parent leaving a thin border where it's docked in the parent. Any idea what I need to do to make it function like the 1.1 version? Thanks, Justin Tag: DataGridView automatically selects first row Tag: 97141

    - Does anyone have an example of the UndoEngine workign with a custom IComponentChangeService implementation? Just trying to figure out how to get a service working that has no viable public methods... My current problem is that nothign ever gets added to the undo stack... All of the other methods are getting called. So my base assumption right now that is that my custom implementation is either preventing the UndoEngine service from getting called or that the designer example from MS that doesn't use a designer class, is unaware of the UndoEngine. ANyway, my head for the designer class is this: public class RootDesigner : IContainer, IDesignerHost, IDesignerLoaderHost, IComponentChangeService, IExtenderProviderService, IToolboxUser, IDesignerEventService { Changing my OnChanged event to trigger the UndoEngine is possible, I'll have to make some public accessor methods on the UndoEngien implementation. However, currently my changed event get's called more than once for 1 user operation. In the case of coping, 1 for the copy and 3 or 4 more for changing properties... This of course would not be a very optimal implementation of undo to have 4 entries for 1 user change. :( Anyways, any help appreciated. Tag: DataGridView automatically selects first row Tag: 97122

    - Autocomplete textbox Hello all! I'm looking for ideas on implementing a textbox with autocomplete functionality, just like the one found in Excel. As the user types values into the textbox a lookup for matching values is performed. For example lets assume that the user types the character '1' and that the candidate values are '01', '02', '03', '10', '12' etc. I need the textbox to display the first candidate value that partially matches the characters typed ('01'). The cursor should be located at the end of the user typed value (1|0) and the rest of the text must be selected. As the user goes on typing, the selected text is replaced with the typed character and the lookup is performed again. I am very close. I use the Textbox.SelectionStart and Textbox.SelectionLength properties but the problem is that the caret is allways placed at the end of the selection when I need it to be located at the begining. Any Ideas? Thanks! PS: I cannot use a combobox! Tag: DataGridView automatically selects first row Tag: 97098

    - Newbie User Interface hangs in multi-thread app Hi, * Apologies for reposting this from .NET Academic * I am having problems updatingh the user interface in a multi-threaded application. BACKGROUND My App has a user interface (the starting class containing main) and a CPU class to handle many asynchronous comms routines. The user interface will be kept updated on the status of the comms by the CPU class. My user interface creates an instance of a class called CPU and passes itself in the constructor this way the CPU can update the user interface by calling a method of UI PROBLEM The user interface is becoming unresponsvie. The cursor turns to the hour glass and it doesnt repaint Although all the comms threads run happily in the background as soon as the CPU tries to call the UpdateScreen method the UI hangs. ASSISTANCE REQUIRED Could you please advise me on how i should go about resolving such a problem. I may well be using bad coding strtegy so pleas advise as you see fit on any aspect. Thanks, Shaun PSEUDO CODE // within the UI class private CPU theCPU; public UI() { theCPU = new CPU(this); } UpdateScreen(string status) { textBox1.Text = status; panel1.Visible= ! panel1.Visible; } // within the CPU class public CPU (UI userInterface) { this.userInterface = userInterface; // start threads to run async comms } private void ReceivedStatusChange() { userInterface.UpdateScreen("Some new status info"); } Tag: DataGridView automatically selects first row Tag: 97091

    - Tactics for Debugging Custom Components with CodeDom Serialized State I have a custom component which has a complex internal state that is serialized using CodeDom serialization. It is part of a library used in a moderately complex project. The component has a custom design-time interface displayed within VS2003. All of the library assemblies are loaded into the global assembly cache on my development machine. This is all under VS2003 and .NET 1.1. Unfortunately, for reasons I have not been able to fathom, the project is very "touchy". Changes to any one of the library assemblies (there are 17) tends to break the deserialization process. I suspect this is due to known problems with VS2003's synchronization of changed global cache assemblies. The resulting error messages are not at all helpful (e.g., Method not found, object cannot be converted to target type). What's worse, I can't seem to "break" on where the problem is occuring, and single-stepping through the component's initialization process doesn't run into any problems. The only clue I've been able to find is that commenting out the following line in InitializeComponent() makes the "object cannot be converted to target type" error message go away): this.AccessControl = new OlbertMcHughLLC.DBFramework.Security.AccessControl("acl", "idnum", "name", "acl_detail", "acl_id", "name", "can_read", "can_write", "can_add", "can_delete"); What's weird about this is that the object being created >>is<<, in fact, of the correct Type...which is why I think the problem is with VS2003's support for syncing assemblies. I'd appreciate hearing any tactics/strategies which others have found helpful debugging these kinds of problems. - Mark p.s. and please, MS support staff, don't ask me to send the entire project to someone -- it's megabytes of source code, and it'd take me a week to explain how it ought to work.

    - Auto Complete/Suggest (On Steroids) I am looking to implement a search feature into a Windows Forms MDI application. Specifically I plan to embed 3 textboxes into a toolbar; one for LastName, another for FirstName, and one for CustomerID. When the user starts typing into any of these textboxes I would like to pop up another form that shows the user a dynamic list of the closest matches. The user can then use the up- and down-arrow keys to select a customer from that pop up form. To see an example of similar ("close-but-not-quite") functionality, go to http://www.thebusco.com/ and in the upper left-hand corner there is a textbox with 'Enter Part Search Here'. Start typing 'air vent cover' to see the behaviour in question. Yes, it's a Web application and I'm doing a Windows Forms app, but it shows you the general idea of what I'm trying to accomplish with Windows Forms. Please note that I am familiar with the new 2.0 features: AutoCompleteMode, AutoCompleteSource, and AutoCompleteCustomSource. But those won't work for my situation because I'm *not* looking to simply populate a textbox or a combo box from the list. What I am needing to do is let the user select the customer for which info is to appear in the currently active MDI form (and not only the control into which they are typing). The idea is that the user starts typing into any one of the 3 textboxes; as they type - the pop up window appears and shows the closest matches. The user then hits the down arrow key a few times to select the desired match, then hits Enter to (1) close the popup window, and (2) trigger logic that shows the selected customer's info in the currently active MDI form. Note that I want to pop up another window [for the closest matches] so that I can show the user many property values for the possible matches (and not simply show them a list of names similar to the one they are searching, for example). What do you see as the biggest challenges in accomplishing this dynamic search capability (and reasonable solutions)? What are the building blocks you might suggest for the solution?

    - Security Model I am designing a new Windows Forms client application (with SQL Server db on the back end) for which users will authenticate via NT authentication (network), or SQL Server authentication. Users who are granted access to the application must also be granted access to specific forms and controls on forms. The menu must show/hide items based on the user's access level. Also, some controls should allow editing by some users but not others (based on their security level). My first thought is to have a static class that gets populated when the user is authenticated. This static class would contain "user profile data", one piece of which is some "security access level" value. Then the menu and all forms (in their form_load event procedure) look to that static class to determine what controls to enable/disable/hide. What do you think about that? Is there some [other] standard/better way to accomplish the security objectives? Thanks! Tag: DataGridView automatically selects first row Tag: 97065

    - Alternative .NET smart client bootstrapper - LagLoader.NET Hi there. In last January, My previous employer got a proof-of-concept project requiring hand drawing on the web; the customer is a fashion design house. I created a .NET Windows Forms control based smart client, encapsulating Tablet PC InkPicture. It worked well (at least for demo) on all my computers. Since .NET framework runtime is a Windows Update optional install, and in the impression that everybody should update their operating systems often with Windows Update, before that project, I got a wrong image that .NET framework runtime should be available easily on every Windows XP PC. No, it is not that case. My customer is no where close to IT industrial; they just made enough bucks, and their younger new boss (whose university major was computer science) decided to invest in a design workflow system. Even though every designer of that customer got a Windows XP PC on each of their desktops for long, and they do have a MIS group doing Windows Update time from time, no .NET framework runtime was preinstalled; they just not awared of that optional install. We found no way to automatically install .NET framework runtime in Windows XP machines of my supposed-to-be users, having to install it one by one, MANUALLY. There were 20+ machines with no .NET framework runtime preinstalled. Remember, this is a smart client solution integrated with a back-end workflow web application solution. It is suppose that no explicit install/setup files should be run on every possible user's Windows. Anyway, even though I have best performance over the category of hand drawing/writting in all competitors, we failed to get that customer to adopt my solution. .NET framework deployment is really an issue. No, it should not be an issue. It was already 1 year ago. Now, .NET 2.0 was released for weeks, ClickOnce is out there, and I got the image that ClickOnce does not support .NET 1.x smart clients. So I am still glad to share my solution to every .NET smart client developer: LagLoader.NET 1.0. Features of LagLoader.NET 1.0: + Detect if the required .NET framework version is installed. Automatically download and install it if not installed. + No code modification is required in existed .NET Windows Forms controls, only minor change in the OBJECT tags in web pages needed. Javascript code worked in the same way to script Windows Forms controls deployed in web pages. + In case that some smart clients are not compatible with the latest version of .NET framework, they may be run fixed to a compatible version of .NET framework, while others being run with the latest version of .NET framework, all in the same web page. + An optional FULL TRUST mode to run Windows Forms control based smart client fully trusted. Smart clients run as fully trusted as their desktop/local peers, but loaded from remote servers. Sure, the full trust mode may hint a security issue, but if you have to do so to perform some tasks, then let it be.

    - Opening, Closing, Launching Forms I'm an experienced ASP.NET C# developer who's just beginning to develop applications in Windows Forms and I would appreciate some references to online material on the above topics. The information is not as prevalent as I would have expected (or maybe I'm searching the wrong topic.) Basically, I'm looking for everything you need to know to launch a Windows Forms application using the static Main() method, how to shut the applications down properly, and specifically how to shut down applications using COM Interop and ActiveX controls. In other words, when working with classes that implement Systems.Windows.Forms.Form while interfacing to unmanaged code, how do you determine at which class level you need to call Dispose() or do you just call it on the Control, the Container and the Form? -- Regards, Fred Chateau fchateauAtComcastDotNet Tag: DataGridView automatically selects first row Tag: 97046

    - Project Data Source Using Derived Interface I've created a project data source based on an interface that in turn derives from another interface. When in Visual Studio Data Sources view I examine the properties exposed by the data source, I see only those properties in the derived interface and none from the base interface. A data source created from a class that implements the derived interface exposes properties from both the derived interface and the base interface. Is it possible to create a data source based on a derived interface that also exposes properties from the base interface? At the moment the only work around I see is to use a data source based on a class that implements the derived interface. Since at runtime I may be displaying data from one of several different classes that implement the interface, I'll be running the risk of a runtime error if I happen to select at design time a property exposed by the class I used as the data source type but that is not declared in the interface.

    - multiple forms/common menu structure I have project where I need multiple forms using a common menu structure (like a web solution but with WinForms). Is there a best way to do it? I'm currently trying inherited forms, but I'm not sure that's the best way as it seems to present challenges. Tag: DataGridView automatically selects first row Tag: 97038

    - DoubleClick Event Won't Fire I have a form with labels that can be dragged and dropped onto different regions of the form either individually or in groups. I signify labels which have been selected by toggling the BorderStyle between FixedSingle and Fixed3D. Upon a single click the toggle occurs. Upon a double click I display a simulated tool tip (label) containing more information about the label selected. I am using the MouseDown event of the label and am using if conditions to branch the single and double click logic using e.Clicks. When the BorderStyle is changed (toggled) on every single click, the double click will never fire. I need to find a way around this without introducing a delay equal to the DoubleClickTime. I also thought I should post this so Microsoft can add it to their patch list. Thanks in advance for any advice you can provide. Here is a sample of code that will reproduce this "feature". Private Sub Pallet_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) '// FYI - handler to this event added elsewhere in code '// closes any open tool tip (not necessary to reproduce bug) CloselblOverFlow_MouseDown(sender, e) '// branches based on # of clicks (type check not necessary to reproduce bug) If e.Button = MouseButtons.Left And e.Clicks = 1 And sender.GetType.Equals(GetType(PalletLabel)) Then Dim lblPallet As PalletLabel = CType(sender, PalletLabel) '// change BorderStyle of sender If lblPallet.BorderStyle = BorderStyle.Fixed3D Then lblPallet.BorderStyle = BorderStyle.FixedSingle Else lblPallet.BorderStyle = BorderStyle.Fixed3D End If '// iniate drag (not necessary to reproduce bug) lblPallet.DoDragDrop(sender, DragDropEffects.Move) ElseIf e.Button = MouseButtons.Left And e.Clicks = 2 Then '// this code will never execute Call ShowOverflow(CType(sender, Control)) End If End Sub Tag: DataGridView automatically selects first row Tag: 97036

I'm setting the datasource of a DataGridView to a datatable. This
loads the grid correctly but it automatically selects the first row in
the grid, triggering the SelectionChanged event. Is there a way to
stop the grid from automatically selecting the first row?

Thanks.

Try handling the DataBindingComplete() event and setting selectedIndex = -1.

You would just as well do this: datagridviewname.ClearSelection(); right
after loading data.
