KeyDown event not firing for all keys on certain cells of a Ultragrid

Brent posted over 13 years ago

I have an UltraGrid control on my form that handles KeyDown events on certain cells without a problem. I am using the keydown event to enable 'Excel-like' navigation between cells/rows using the arrow keys. However, certain cells don't appear to fire the KeyDown event when the arrow keys are pressed. When they are pressed the focus moves to a different control on the form. Other keys seem to work fine, i.e. the event is fired.

The cells where this occurs have checkboxes or masked text (formatted date/time) and all are set to 'NoEdit'. I'm reasonably certain this is the root of the problem, but I've read that the UltraGrid's keydown event should still fire for these cells.

Any suggestions on what might be consuming the KeyDown message before the UltraGrid receives it?

Hello Ayrus,

I have tried this using NetAdvantage for Windows Forms 2011 vol2 and it works fine for me.
Could you please verify that your UltraGrid has the focus when you are pressing F1, and also if it is hooked correctly to the mentioned KeyDown event ?

What version of the NetAdvantage controls you are using in your application?

If you have any other questions please feel free to let us know.

Hi,

None of this seem to be working; not sure if there any issue with my code.

Please could you evaluate below code:

Private Sub UltraGrid1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles UltraGrid1.KeyDown

        If e.KeyCode = Keys.Enter Then
            MsgBox("Enter eydown")
        ElseIf e.KeyCode = Keys.F1 Then
            MsgBox("F1 clicked")
        End If

' Or

        If e.KeyData = Keys.F1 Then
            MsgBox("F1 clicked")
        End If

    End Sub

Hello Ayrus,

Your code is actually checking if you have pressed "F10" instead of "F1":

ElseIf e.KeyCode = Keys.F10 Then
MsgBox("F1 clicked")

End If

If you change the Keys.F10 to Keys.F1 it should work.

Please feel free to let us know if you have any other questions with this matter.
