Hai,
I am using Infragistics 2007 vol 3. I am using a grid in my form. I have a button in the form to display the Row filtering in grid. First i click that button to show the row filter. Then i again click to make it invisible. After my filter row got invisible, if i scroll the mouse wheel , i got the following error (on scrolling mouse over the grid) :
at Infragistics.Win.EditorWithCombo.ProcessOnMouseWheel(MouseEventArgs e)
at Infragistics.Win.EditorWithCombo.OnOwningControlMouseWheel(Object sender, MouseEventArgs e)
at System.Windows.Forms.MouseEventHandler.Invoke(Object sender, MouseEventArgs e)
at System.Windows.Forms.Control.OnMouseWheel(MouseEventArgs e)
at Infragistics.Win.UltraWinGrid.UltraGridBase.OnMouseWheel(MouseEventArgs e)
at System.Windows.Forms.Control.WmMouseWheel(Message& m)
at System.Windows.Forms.Control.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)
Somebody guide me why this error coming to me and what to do to avoid this error.
Thanks & Regards

Assuming it was a NullReferenceException, there was a bug that was very recently fixed whereby an exception would be thrown if the editr was not accociated with a ValueList. You might want to report this and include a test project so Developer Support can determine whether this has already been addressed; if it hasn't, a separate incident would then be logged.
We are also getting this error in our application after doing some combination of actions and then doing a mouse scroll. It's a NullReferenceException alright but I'm pretty sure all the editors are associated with a ValueList. Any idea? Also, I'd like to try the fix that you mentioned, where can I get it?
Also, in case the released fix above didn't work, is there a way I can trap this error and not display it?
Thanks!
Check in the Grid's beforeexiteditmode event.
If you have the latest service release and this bug is still occurring, then you should create a small sample project demonstrating this and Submit an incident to Infragistics Developer Support so they can check it out.
No error is being trapped in grid's BeforeExitEditMode. I also tried trapping any error under AfterExitEditMode as well as MouseWheel event but to no avail. Moreover, I verified that the ValueLists are still existing under those methods/events.
Any ideas?
