Hello!

I got a whard problem with UltraCombo.

When I leave the combo with a TAB I get an exception that forces application to exit even when I covered all methods with try and catch blocks. Exception message is: "Can't access SelectionStart unless editor is in edit mode".

Here parts of the stacktrace:

at Infragistics.Win.EmbeddableEditorBase.get_SelectionStart()

   at Infragistics.Win.UltraWinGrid.UltraCombo.OnBeforeEditorExitEditMode(Object sender, BeforeExitEditModeEventArgs e)

   at Infragistics.Win.EmbeddableEditorBase.OnBeforeExitEditMode(Boolean& cancel, Boolean forceExit, Boolean applyChanges)

   at Infragistics.Win.EditorWithText.OnBeforeExitEditMode(Boolean& cancel, Boolean forceExit, Boolean applyChanges)

   at Infragistics.Win.EditorWithCombo.OnBeforeExitEditMode(Boolean& cancel, Boolean forceExit, Boolean applyChanges)

   at Infragistics.Win.EmbeddableEditorBase.ExitEditMode(Boolean forceExit, Boolean applyChanges)

   at Infragistics.Win.UltraWinGrid.UltraCombo.OnEditorKeyDown(Object sender, KeyEventArgs args)

   at Infragistics.Win.EmbeddableEditorBase.RaiseKeyDownEvent(KeyEventArgs e)

   at Infragistics.Win.EmbeddableTextBox.OnKeyDown(KeyEventArgs e)

   at Infragistics.Win.EmbeddableTextBoxWithUIPermissions.ProcessKeyMessage(Message& msg)

   at System.Windows.Forms.Control.WmKeyChar(Message& m)

   at System.Windows.Forms.Control.WndProc(Message& m)

   at System.Windows.Forms.TextBoxBase.WndProc(Message& m)

   at System.Windows.Forms.TextBox.WndProc(Message& m)

I try to prevent firing an event when TAB is pressed, but which event can be supressed or how can I send the combo into edit mode?

I'm using Infragfistics Win 6.1

Thanks for any advice.
