    - "Error: Subreport could not be shown" I have a Winform application (.NET Framework 2.0) that displays several local reports using the ReportViewer control. I have two main reports (referred to here as A and B) that display a subreport (referred to as C). On the machine used to develop this application, all reports, both main and subreport, run successfully when executed in the VS 2005 environment and from running the executable directly. After xcopying the application to a different machine, reports A and B are displayed successfully except the subreport displays "Error: Subreport could not be shown". Any ideas on how to figure out what is going on, or are there any know issue with subreports being displayed in the ReportViewer control? Tag: ReportViewer Expand DocumentMap Tag: 113883

    - DataGridView binding recommendation for multithreaded apps I have an application that needs to display a couple of lists to the user and I would like most of the work to be done by a background task. The data displayed is read only. Because of the other work being done in the UI, I need to limit as much as possible the UI thread work load when it does not have the focus. So, how best do this? Option 1 (And this takes too long in the UI tread): The background (bg) task does all the sql and updates the data table. When the bg task has an update, it signals the UI. The UI task takes a copy of the data table and binds it to the data grid. Normal object locking is used. Option 2: Modify option one to just push the update rows across the task boundary. I know this will be better, but I donâ??t know if itâ??s the best approach. Option 3: Build an object that uses the property changed event and have the binding source bind to the type. This works just fine, but the data grid update is not smooth (aka the screen flickers) so it has to be rejected. Option 4: Bind a synchronized list to the data grid view and have the bg thread signal the UI thread when the data grid view should be invalidated. In my simple case, Option 4 looks the cleanest since I donâ??t need any of the features (row states, relationships) of the data table object. Thanks for the comments and other ideasâ?¦Chuck Tag: ReportViewer Expand DocumentMap Tag: 113878

    - Determining when a form or child control is activated Sorry if this is a really dumb question. I have an application with various forms The forms may be shown using Show or ShowDialog but my also be re-parented to a control in another form (e.g. a Windows Forms Panel). What I'm trying to do is find some reliable way to determine when a form is activated. I had thought that the Activated event would do what I needed but I don't get that event to ever fire. I derived a form from Windows.Forms.Form to see if I could do something there but so far no luck figuring it out. Thanks in advance for any pointers or advice. -- Neil Tag: ReportViewer Expand DocumentMap Tag: 113877

    - Background Form I have a form that I open with ShowDialog(). I have a background form that I initially open to make a background behind the user input form. The code is like this: static Form BackForm=null; public bool InputMethod() { if(BackForm==null){ BackForm = new Form(); // set up backform and make it maximized. BackForm.Show(); } Form InputForm=new Form(); // set up the input form here. InputForm.ShowDialog(BackForm); } This basically works the way that I want it to, I call InputMethod() a bunch of times, it puts up the BackForm once, then the smaller InputForm comes and goes for input. The problem is that BackForm does not behave properly in Windows, if you minimize InputForm, BackForm is still there, and does not minimize, and can not be minimized. Is there a way to do this? Is there something like an OnMinimize event that I could override for InputForm, and minimize BackForm in it? Or a better way of having a background that does not flicker between InputMethod() calls, without InputForm being maximized? Thanks for any suggestions.

    - Toolstrip and MDI application I am trying to get write an MDI application running using the ToolStrip control(s). I have the application running with types of two form. Each form represents a type of document. Each has its own custom menus and toolbars. The MDI application runs up and I create new documents of each type. When a form is activated, dot net merges the menus and the app I merge in the toolbars using RevertMerge and Merge. One of my forms has about 6 toolbars, the other has 2. When I switch between the two document type, the toolbars change position; I activate form1, move the toolbars using the mouse, activate form2, then switch back to form1- the toolbars have moved. I am also having problems saving and restoring the positions of the toolbars using ToolStripManager.LoadSettings and ToolStripManager.SaveSettings. This showing the same behaviour (although it may be caused simply by switching between the windows). Has anyone successfully implemented an MDI app using these controls? I have a test app if anyone would like to see it - where the best place to post it? Paul Wardle Tag: ReportViewer Expand DocumentMap Tag: 113857

    - TreeView flickering while searching nodes Hi, I see a lot about TreeView flickering while adding nodes to a treeview control, but not really about what I'm experiencing. I'm adding nodes to a TreeView control, but first, to ensure I don't already have a node somewhere in the tree with the same name, I perform a recursive search of the nodes for nodes containing a specified text value. The TreeView control flickers while searching the nodes. I've tried using .SuspendLayout() and .ResumeLayout() before and after each search is initiated, but it still flickers. Any ideas on how I can keep the control from flickering while searching the nodes? Thanks, Charlie Tag: ReportViewer Expand DocumentMap Tag: 113847

    - Splitter Vs. SplitContainer in MDI Applications Hello, I'm reading through Chris Sells & Michael Weinhardt's Windows Forms 2.0 Programming book, and finding it incredibly useful as a quick- reference manual. Reading up on the Splitter & SplitContainer controls, they mention that "you may need to use the pre-Windows Forms 2.0 Splitter control for MDI applications." Browsing through their MDI application chapter, I see no further mention of the Splitter or SplitContainer. Under what conditions would you need to use a Splitter rather than a SplitContainer?

    - Drag and Drop events not firing Ok, this is the first time I've tried a serious use of Drag and Drop. As a test, I first defined 2 instances of a very basic user control on a form. The user control had one string type public property. All the dragdrop event handlers needed were defined automatically by VS from the individual instances (MouseDown, MouseMove, DragEnter, DragDrop). (This was all based on that article http://msdn2.microsoft.com/en-us/library/aa289508(VS.71).aspx - Implementing Drag and Drop in VisualBasic.Net) This test worked fine. (I also went back and assigned a panel as the 2 usercontrols parent. It still works.) Now in the real application, what I want to do is dynamically define a number of usercontrols based on the data and attach them to a panel. In other words, define a loop and for each record: Dim x as new UserControl1 -- define it's properties -- Attach the event handlers AddHandler x.MouseDown, AddressOf ControlMouseDown AddHandler x.DragDrop, AddressOf ControlDragDrop AddHandler x.MouseMove, AddressOf ControlMouseMove AddHandler x.DragEnter, AddressOf ControlDragEnter Now the event handlers aren't firing, not even MouseDown. I've set the AllowDrop property of each control instance to True. What else could I be forgetting? Tag: ReportViewer Expand DocumentMap Tag: 113830

    - WinForm with Dynamic Controls and Model View Presenter Hi, I have a WinForm control that has a tab control on it as its only control. In the code I am dynamically adding controls to the tab control dynamically. You could picture a page that gets populated with questions with either radio buttons for choices, or perhaps combo boxes whose items come from the database. All of these controls are placed on the tabs depending on answers to questions - so if you answer "yes" to question "A" for example, then another question may appear on this same tab, or a new tab may be added and have additional questions on it. I am looking at doing this all using the Model View Presenter pattern and was wondering if anyone had done anything like this before? I am not sure what the best design might be to pass the controls and data to the View as the controls will have to be "added" to the tab control. If anyone has done anything like this and has any recommendations, I would be appreciative to hear about designs. Also, I don't know if there would be any benefit from doing this using WPF instead of .net 2.0 WinForms. Any thoughts about this would be appreciated as well. thanks in advance!

    - scaling UI (higher resolution => bigger buttons + bigger font) I want to create a UI with Windows Forms that should scale with the resolution. It's some sort of demonstration UI to be used on presentations. For example: my application is always maximized and lets say it contains 4 big buttons (in 2 rows and 2 columns) that completely fill the screen. When it runs on a 800x600 screen it should fill all space. When it runs on a 1600x1200 screen it should also fill all available space. I have already used a tableLayoutPanel but this only scales the controls, not the font. Is the tableLayoutPanel the right tool for this job? And can it also dynamically change the fontsize?

    - change location of control Hi all, I have a form that inherits from another form. I want to change the location of a specific control.

The control's location changes but not to (0,0). When I call this method from inside the base form it does work(changes to 0,0). It looks like the inheriting form can't touch some certain area.

    - Using ComboBox in DataGridView with custom classes as datasource Hello. I'm working on a telephone directory lookup for an application and have a custom class I would like to show in a datagridview. The problem is that a person might have more than one mobile phone registered, but the application expects only one, so the user will have to choose one. My idea was to use a DataGridViewComboBoxColumn in a datagridview to let the user choose one of the phone numbers. This is the class: public class PersonInfo { private string _name; private string _address; private string _workPhone; private string _homePhone; private string[] _mobilePhone; public PersonInfo(string name, string address, string workPhone, string homePhone, string[] mobilePhone) { this._name = name; this._address = address; this._workPhone = workPhone; this._homePhone = homePhone; this._mobilePhone = mobilePhone; } public string Name { get { return _name; } } public string Address { get { return _address; } } public string WorkPhone { get { return _workPhone; } } public string HomePhone { get { return _homePhone; } } public string[] MobilePhone { get { return _mobilePhone; } } } The problem is getting the numbers in the MobilePhone property to show up.

    - Problem rendering metafile text on bitmap. Hi, I have a problem with the quality from metafiles rendered on a System.Drawing.Bitmap. In particular, text is drawn poorly. If the same metafile is rendered directly onto a form's drawing surface, the quality is fine. There's also a problem with scaling, with a difference in size between the bitmap and directly drawn versions. The code below illustrates the problem. It draws a string three times. The top one is the string drawn directly on the form. The middle one is from a metafile (with the string drawn onto it) drawn directly onto the form. The bottom one is from the same metafile, rendered onto a bitmap, which is then drawn onto the form. Top two look fine, bottom one not so good. Any ideas what I'm doing wrong? Thanks, Chris. Bitmap bitmap; Metafile metafile; private void button1_Click(object sender, EventArgs e) { using (Graphics formGraphics = CreateGraphics()) { IntPtr handle = formGraphics.GetHdc(); metafile = new Metafile(handle, EmfType.EmfOnly); formGraphics.ReleaseHdc(); using (Graphics metaGraphics = Graphics.FromImage(metafile)) { metaGraphics.DrawString("Test string", new Font("Arial", 14), Brushes.Black, new PointF(0, 0)); } bitmap = new Bitmap(400, 100); bitmap.SetResolution(formGraphics.DpiX, formGraphics.DpiY); using (Graphics bitmapGraphics = Graphics.FromImage(bitmap)) { bitmapGraphics.DrawImage(metafile, new Point(0, 0)); } formGraphics.DrawString("Test string", new Font("Arial", 14), Brushes.Black, new PointF(0, 0)); formGraphics.DrawImage(metafile, new Point(0, 50)); formGraphics.DrawImage(bitmap, new Point(0, 100)); } } Tag: ReportViewer Expand DocumentMap Tag: 113784

Here is the AutoGenerated code for that control: // modifiedDateDateTimePicker // this.modifiedDateDateTimePicker.DataBindings.Add(new System.Windows.Forms.Binding("Value", this.bsMTask, "ModifiedDate", true)); this.modifiedDateDateTimePicker.Enabled = false; this.modifiedDateDateTimePicker.Location = new System.Drawing.Point(129, 366); this.modifiedDateDateTimePicker.Name = "modifiedDateDateTimePicker"; this.modifiedDateDateTimePicker.Size = new System.Drawing.Size(200, 20); this.modifiedDateDateTimePicker.TabIndex = 25; Here is exception text that is returned when I get the error: "Column 'ModfiedDate' does not allow nulls." ************** Exception Text ************** System.Data.NoNullAllowedException: Column 'ModifiedDate' does not allow nulls. at System.Data.DataColumn.CheckNullable(DataRow row) at System.Data.DataTable.RaiseRowChanging(DataRowChangeEventArgs args, DataRow eRow, DataRowAction eAction, Boolean fireEvent) at System.Data.DataTable.SetNewRecordWorker(DataRow row, Int32 proposedRecord, DataRowAction action, Boolean isInMerge, Int32 position, Boolean fireEvent, Exception& deferredException) at System.Data.DataTable.InsertRow(DataRow row, Int32 proposedID, Int32 pos, Boolean fireEvent) at System.Data.DataView.FinishAddNew(Int32 currentIndex, Boolean success) at System.Data.DataRowView.EndEdit() at System.Windows.Forms.CurrencyManager.EndCurrentEdit() at System.Windows.Forms.BindingSource.EndEdit() at HIP2007.AddEditMasterTask.btnSave_Click(Object sender, EventArgs e) in M:\HIP2007\HIP2007\Dialogs _ CurrentWork\AddEditMasterTask.cs:line 92 at System.EventHandler.Invoke(Object sender, EventArgs e) at System.Windows.Forms.Control.OnClick(EventArgs e) at System.Windows.Forms.Button.OnClick(EventArgs e) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) I thought that the default value of the DateTimePicker was the value that is displayed in the control - the current datetime. BTW I have disabled this control from user interaction so that it will behave as read only. What do I do so that today's datetime is by default put into the control so I do not receive this error? Thank you. Doug Tag: ReportViewer Expand DocumentMap Tag: 113766

    - Catching mouse events on all child controls Greetings, I've already tried googling for the following problem, but it seems every solution I've found is too complex and error prone. I've got a control (Panel) that acts as a container for several other controls. These controls, in turn, have several other controls and so on. I wish to be notified whenever the mouse is hover the area defined by the container control, regardless of its children. OnMouseEnter and OnMouseLeave triggers as soon as the mouse enters/leaves a child control, so I can't use them. Same applies for OnGotFocus/OnLostFocus. One solution would be to hook upon all events in every child control. Despite the resulting complexity of event triggering (and the fact that some controls can simply override the events I'm listening for and inhibit them), the controls I'm using can (and will) change in run- time (we are talking about adaptative interfaces here); this would probably mean that I also need to hook upon the ControlAdded and ControlRemoved events. So my question is simple: is there any "clean" way for a control to know that a mouse is in its area (ClientRectangle)? I don't mind if the solution involves WndProc... Best regards and thanks in advance, Hugo Ferreira Tag: ReportViewer Expand DocumentMap Tag: 113765

    - Very weird RichTextBox bug I have tried to make a simple sample of this - but the simple samples all work. The basic problem is I create a RichTextBox and then call RichTextBox.LoadFile() to load a rtf file in it. If the file has an image in it - the control displays nothing and RichTextBox.Text returns "". If I do the same thing in my simple sample program, it all works fine. Where it does not work I have a Word AddIn (IDTExtensibility2, not VSTO) that uses DevExpress for it's ribbon forms, etc. In it to display the rtf file I bring up a Form that has a RichTextBox in it and call LoadFile(). And if the rtf has an image in it I get a blank control. To try and recreate it I just did a plain old Windows form - no DevExpress and no Word AddIn. But that works fine. Has anyone ever heard of anything like this? -- thanks - dave david_at_windward_dot_net http://www.windwardreports.com Cubicle Wars - http://www.windwardreports.com/film.htm Tag: ReportViewer Expand DocumentMap Tag: 113761

    - Set the row background color according to a cell value Hi, At this time I'm able to set the background color of a cell depending on it's value. I'm able to achieve this by extending the DataGridTextBoxColumn class and overriding the Paint method: [code] protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, CurrencyManager source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush foreBrush, bool alignToRight) { if (internalHighlightInformation != null) { object objAtRow = GetColumnValueAtRow(source, rowNum); //(Values A, C and X are just an example, this values are set at run-time) if (objAtRow = "B" || objAtRow = "C" || objAtRow = "X") { backBrush = new SolidBrush(Color.Red); foreBrush = new SolidBrush(Color.White); } } base.Paint(g, bounds, source, rowNum, backBrush, foreBrush, alignToRight); } [/code] My problem now is, how can I do this to the full row? At this stage I know the row number, and the cell, but I don't have any access to the cells that exist in the same row :( (or do I?) Any ideas? I just cannot figure out how to do this... Thanks ahead for all the help. Best Regards, L. Pinho Tag: ReportViewer Expand DocumentMap Tag: 113757

    - Beginners question - DataGridView with a combo box column I have not tried this before. I have a fairly simple table bound to the grid itself and I want to make one of the columns a combo box. To this end I bound the grid to the first table and the column to a second. No matter what I try, I keep getting 'DataGridViewComboBoxCell value is not valid.' How does one normally set up an arrangement like this and how do I begin troubleshooting this? Tag: ReportViewer Expand DocumentMap Tag: 113756

    - I need to be able to trap when the user clicks on a Web Browser control. So the .NET 2.0 web browser control does not provide a MouseDown or Click event handler, but I have a need to trap on this. I would like to know the best approach to accomplish this. I see Enter and Leave event handlers on the control and I have tried to trap on these and then check the MouseDown event on the parent, but this doesn't seem to work. Is there an approach I can use with API calls. I don't require an 100% managed solution. Thanks. Tag: ReportViewer Expand DocumentMap Tag: 113754

    - ListView - one column Hi everybody, I want to have a ListView which has only one column and all the items have the width of the listview (that is, no room fro subitems since i don't need them). It may sound like a ListBox, but I need to have ListViewItems and not objects in the control. Thanks in advance, -- Mihai TÄ?tÄ?ran H.P.C.

    - Component Designer A great problem on VS2005. After I dropped an object on the design area of a component, it does not maintain the position assigned. All objects, after closing and reopening the designer, move on the left of the area. It's hard to work in this situation. VS2005 SP1 resolves the situation? Please, help me!!

    - Exceptons when debugging My VB 2005 winforms application has an Application.ThreadException handler to catch any unhandled exception. When debugging, the debugger doesn't stop when I get an exception, control passes to my application exception handler. Currently I comment out the handler to be able to get the debugger to stop when an unhandled exception occurs. Ideally I would like to have the debugger stop when any exception occurs, then optionally be able to proceed by having the exception bubble up. Is this possible?

    - PictureBox.Load and animated GIFs Loading an animated GIF using PictureBox.Load causes an ObjectDisposedException with the message "Cannot access a closed file" to be thrown in the FileStream.Read method ultimately called by ImageAnimator.UpdateFrames. Looking at the output from ILDASM, it seems that the underlying file stream is being disposed in the PictureBox.Load method. However, KB article 814675 states that the stream must not be destroyed for the lifetime of the image. Can anyone shed some light on whether the .NET framework really is closing the stream before the image is finished with. Thanks Tag: ReportViewer Expand DocumentMap Tag: 113739

On the Winform ReportViewer control (.NET Framework 2.0), is there a way to
expand the DocumentMap tree by default? I am NOT talking about the
ReportViewer.DocumentMapCollapsed property. I want the tree displayed in the
DocumentMap to be expanded by default. Currently, the report is displayed to
the user, and the first thing they do is expand the tree to select the
document map elementt they want to display. The desired functionality is
when the report is displayed to the user is that the document map tree view
control would be expanded and the first node in the tree selected by default.

Thanks in advance.
