 - ListView.SelectedIndexChanged problem 1. ListView has Multiselect = true 2. I handle the above-mentioned event. 3. SelectedIndices collection has 0 elements when navigating by mouse-click or up/down arrow I need to have Multiselect on to support deleting multiple items at time. But I tried with multiselect=false, and I still get SelectedIndices collection with 0 elements. All this leads me to believe that .NET 1.1 ListView has a bug. Tag: Paging in Windiws Datagrid.

 - MDI Child Form Not Releasing DataSet I have an application that creates MDI child windows to edit different datatables in the same dataset. At one point in the application cycle, users have the opportunity to log off the database server (so they can reconnect to a different one). As part of that log off, I clear the dataset. Unfortunately, if an MDI child form has been opened and then closed, the datatable for that form hangs on the clear (i.e., aDataTable.Clear() stalls forever). This problem does not occur if that table's form has not been opened and closed. This seems to be a problem where the MDI child form, while "closed", is still maintaining a reference to the datatable (probably through databinding?). How do I get rid of this reference so that datatable can be cleared? I've tried setting the MDIParent property of the MDIChild form to null in an event handler for the MDIParent form that watches for MDIChild Close events, followed by a call to MDIChild.Dispose(). Unfortunately, that does't solve the problem. Any leads or workarounds would be greatly appreciated. - Mark p.s. BTW, this is looks to be the second "silent failure" of the NET Framework I've come across in the past week (the first had to do with the way the Framework's handling of DBNull values for bound DateTimePicker controls breaks the BindingContext.Position code, with no outward sign of a problem). I'm beginning to think the NET Framework design team didn't take enough advantage of exception handling in developing the Framework. Tag: Paging in Windiws Datagrid. Tag: 56184

 - automatic code generation I'm not sure if this is the right forum, but it has to do with the automatic code generation of a WinForm for the Compact Framework. Anyway, I thought I'd report an issue I've been having. I subclass a control to define my own button class that can draw custom images (since the CF does not permit this as is). Anyway, to add it to my winForm, I manually add it in among the automatically generated code, adding it to the proper tab control, etc. I build it, run it, and it works fine. Sometimes if I then hide the automatically generated code (w/ my newly added code interspersed) and proceed to edit the WinForm through the GUI interface provided in VS .NET 2003 C#, at some point, the code I intertwined w/ the automatically generated code disappears. I haven't nailed down the exact procedure that causes the problem b/c each test I have to re-write the inter-mixed code. Right now it isn't a big deal for me, but in the future it might become an issue. I suspect that at some point, the compiler may be re-generating the automatically generated code but doesn't realize I've edited it? Oh, and before it removes the code, an error might pop up saying my class is uninitialized, but if I build my project, it sees that it is initialized (among the auto-gen code) and builds fine.

 - Alternative to TransparencyKey property? Hi, I'm trying to convert an application from C++ to CSharp. Under C++ I used the SetLayeredWindowAttributes() API to make parts of my form transparent. Now in CSharp, I was trying the forms TransparencyKey property. However, it doesn't work on my system with 32bit display and I found this confirmed by other posts on this topic. I asked myself if I could avoid this problem by dllimport-ing the API function. I'm very new to CSharp and Dotnet and could not get it working, yet. I would really appreciate if anyone could tell me what is wrong in the following code: //the original function signature /* BOOL SetLayeredWindowAttributes(HWND hwnd, COLORREF crKey, BYTE bAlpha, DWORD dwFlags ); */ //define the key constant private const int LWA_COLORKEY = 0x00000001; [DllImport("user32.dll", SetLastError=true)] public static extern int SetLayeredWindowAttributes(int hwnd, int cKey, byte bAlpha, int dwFlags); //in the forms constructor int ret = SetLayeredWindowAttributes(this.Handle.ToInt32(), 0x00FFFFFF, 0, LWA_COLORKEY); if(ret == 0) { try { throw new Win32Exception(); } catch(Exception err) { MessageBox.Show(err.Message); } } thanks for any ideas, Nick Tag: Paging in Windiws Datagrid.

 - Mouse Events in Nested Controls Hi all, I am wondering what the "normal" behavior for mouse events(click,down, etc..) within nested controls is. Do the mouse events fire for the container control and the child control if you click on the child control? Or only the child control? or only the parent control? The reason I am asking is because I have a Panel which has many child Panels within it. When I hook up a mouse event (mousedown,click) to the parent, it does not fire when I click on the child control. I was hoping it would fire so I could use GetChildAtPoint to access the child control. The event DID fire when I clicked on part of the panel without a child control. I then opted to hook up the mousedown event inside my child control and simply have it act upon the parent control to do the work. Unfortunately, the event does not fire here either!? Am I missing something? Is there a property that must be set correctly to make this work? Thx in advance, Cole Tag: Paging in Windiws Datagrid. Tag: 56176

 - DataGrid and unbound text boxes I'm building a VB.Net Windows form application. I have a DataGrid and 5 unbound textboxes on a form. The DataGrid is populated with a OleDbDataAdapter and is using a table called Clients. What I want to do is have the users fill in the unbound textboxes and click a button and have those values inserted into the table clients. I will then refresh the datagrid and the new values will appear. I created a New Connection, A New DataSet and A New Select Command to the table Clients. When I Create a datarow like so: Dim drw2 As DataRow drw2 = DataSet1.Tables("tblClients").NewRow I recieve a error " Object reference not set to an instance of an object......" When I look up the error it looks like the new select command I've built is interfering with the one on the OleDbDataAdapter. Does anybody have any workaround ideas?

 - Memory Issue I am developing a application and I think I have a memory leak, but I am not sure. TESTS: 1: I open and close a edit window I have work on for 2 weeks the memory grows by 6MB 2: I open and close the same edit window with no code, no data just controls and the memory grows by 6MB 3: I create a brand new form with a couple of random controls and no code and I open and close it the using the same SUB, memory does not increase at all. Something seems to be wrong with my window however I have no idea what. Could someone give me some insight into why this would be happening. I really do not want to cut and paste all my code and controls into another window just to find out I still have the same problem. Tag: Paging in Windiws Datagrid. Tag: 56163

 - how to set focus on a combobox on a tab when the form is loaded? Hi, I have a form with 3 tabs and each tab has a combobox on it. When the form is loaded, I determine which tab to display based on parameters passed into the form's New() method. When the form is loaded, I would like to place the cursor in the combobox of the selected tab, place some text in the combobox, and highlight the text. However, not only am I unable to get the cursor in the combobox (combo.focus () executes, but does not do it), assigning the text to combo.text does not show the text in the combobox. combo.SelectAll combo.SelectedText = [my text] creates an error, apparently because combo has not been fully loaded yet.

 - how to set focus on control in a tab on tab click? Hi, When I click a tab on my form, I want a combobox on that tab to be given the focus (I want the cursor to be sitting in the combo, blinking, and if the user starts typing, the text should appear in the combo). Setting the focus from the tab.SelectedIndexChanged event does not do it. The combo seems to have focus (if I type, the characters appear in the combo), but the cursor is not visible until I click in the combo. Any thoughts? Thanks, David Tag: Paging in Windiws Datagrid.

 - Book Suggestions Please! I have had VS7 for about a year now and use C# mainly. The apps that I write are for my own use on the desktop so ASP/Web applications hold little interest for me. I tend to use the Win API a lot still but I suspect that there are better ways. I am looking for book(s) that give details of the various namespaces and the functionality within them (I know it's in the help but I can't read that in the bath) and especially any books that will ease the transition from the API to inbuilt functionality (assuming it's there). Books that show how to use the API for things like shell hooks and how to show the system context menu would be very much of interest. I liked the earlier Petzold books because they gave a complete breakdown of the API and also Appleman's book on VB6 and the API. I have I got Petzold's Programming Windows, Jesse Liberty's Programming C# and Mueller's .NET Framework Solutions. They look good on the face of it but are very basic once you get into them and really add nothing beyond the excellent help system in VS.Net. Any suggestions would be appreciated, those I have searched for usually end up being about writing Web apps rather than Windows Forms apps.

 - How to detect closed form? I have opened form from another form and I have an variable with reference on it. But what if someone close referenced form? I tryed to test an variable on Nothing value but there is still reference on closed form. The questin is: How can I find out that the referenced form is closed. I have two ideas: 1) Exception handling 2) Handle closed event of closed form Is there some better way? And another problem. When a referenced form is closed, I can still run frm.Hide() without throwing exception, but frm.Show() fires exception. Object is closed, so why frm.Hide() doesn't throw the exception too?

 - Cancelling current activity in progress indicator Hi all, in my application I want to implement a progress indicator which has 'Cancel' button allowing to interrupt the current activity. What is the best way to do such a thing? I'm considering the following variant: The progress indicator is created on demand on the separate thread and stored in the local memory of the thread that has initiated its creation ('initiating thread'). The progress indicator also stores a reference to the initiating thread. When a user clicks 'Cancel' button, a delegate is executed on the initiating thread that throws an exception, so that it can be handled somewhere on the initiating thread. The purpose of creating progress indicator on a separate thread is that it will be unable to handle windows messages (like clicking 'Cancel') if it is created on the initiating thread. Am I right or I'm reinventing the wheel and there is an easier way? I would prefer simpler design, but I'm not competent enough in WinForms to figure it out.

 - Date Web Service Has anybody seen a web service that can check the date. I wish to use this as a simple shut down for a software product. Instead of checking the computer's date, which can be changed by the user, I could require an Internet connection and check the real date with a web service. A simple yet effective way to shut down a program. Anybody seen this web service? Derek Tag: Paging in Windiws Datagrid. Tag: 56037

 - Panel autoscroll position Can anyone help? Why do some controls reposition themselves to the correct position automatically when I scroll my panel. Others I have to manually reposition. In the If statement: control is to the left of the autoscroll position. The ElseIf: control is to the right of the autoscroll position. This works fine on all controls that do not reposition themselves automatically. They are all invisible before reposition. Could it have something to do with the ZOrder. I've tried bringing them to front first. 'move groupbox according to autoscrollposition of panel(pnlcategory). Public Function MoveGroupbox(ByRef pnl As Panel, ByVal grpbox As GroupBox) As Integer With grpbox If Math.Abs(pnl.AutoScrollPosition.X) > .Location.X Then .Location = New Point(0 + pnl.AutoScrollPosition.X - .Location.X, .Location.Y) ElseIf Math.Abs(pnl.AutoScrollPosition.X) < .Location.X Then .Location = New Point(0 + pnl.AutoScrollPosition.X + .Location.X, .Location.Y) End If End With Return grpbox.Location.X End Function Thanks , Daniel Jenkins Tag: Paging in Windiws Datagrid.

 - PropertyGrid Collections do not fire PropertyValueChanged Hi, I have a collection in an object that can be edited by a propertygrid. When the user edits properties the PropertyValueChanged event fires and I can mark my object as dirty (ie needs saving) but if the user edits a collection contained in the object the event doesnt fire. Whats the best way to get notifications if collection contents are changed? BM Tag: Paging in Windiws Datagrid. Tag: 56027

 - How do I support MouseHover over different TreeNodes in one TreeView? I have a TreeView with more than one TreeNode. I would like to do something like set a ToolTip during a MouseHover event. Unfortunately, since TreeNodes don't generate events. The TreeView owns the MouseHover event, but it generates only one event per session of moving from TreeNode to TreeNode. I could move most of my logic into the MouseMove event, but I don't want to recalc everything everything on every MouseMove over the TreeView, as it could slow down the mouse motion. I greatly prefer the delay the MouseHover event gives me. Ideally, there would be a way that I can cause subsequent MouseHover events to be generated after a MouseMove event over a different node from the last MouseHover event. Is there something?

 - Datagrid Index Out of Bounds Hi, I have a form with a datagrid that loads a modal dialog when the f3 button is clicked. A value from a read only datagrid in the modal dialog is double clicked, the modal dialog is closed and the value is returned to the main form's datagrid cell. This works fine but when I attempt to tab out of the cell, I get an index was outside the bounds of the array error, which is coming from the modal dialog. I have tried things such as setting currentrowindex but no success. Any ideas? Thanks in advance. Tag: Paging in Windiws Datagrid. Tag: 56023

Hi,
i am having one datagrid, i am fetching more than 25k
records in that datagrid.
At present i am displaying all the records in one grid.
so the datagrid takes hell lot of time to fetch record
from database and displaying it.
Whether paging is allowed in Windows C# forms ? Or any
other way to implement paging ?

Thanking in Advance.

Hi Mahesh,

I have been thinking about this, too. Currently, there are 2 approaches:
1. provide a filter property the user can use to limit the result set size,
2. limit the number of rows that are fetched in the select statement (select....fetch first 100 rows only or something like that),
and implement a paging logic such as web search engines do. Somewhat unusual for a windows application, I think
3. Execute the DataAdapter.Fill( DataTable ) in a background thread.

Ok, that are 3 methods. Currently, I've only done the first.

HTH, Ulrich
