  Hi,
  
  I click with tab through the window - problem is that I have to press two times in the DataGrid, that the focus comes to the button.
  
  I include you the sample and also a video.
  
  Additional - with old version from 2018 it works - now 4.6.2 not.

  Hi Patrick,

  We could replicate the behavior at our end.

  By pressing the ‘Tab’ key in Datagrid version 4.6.2, we can traverse through each row.

  By pressing the Tab key, Datagrid rows are not traversed on the previous version (2018). Therefore, with just one “Tab” key hit, the focus gets shifted away from the Datagrid. (See tabFocus.zip)
  
  

  The behavior shown by the 4.6.2 version seems to be valid to us when we have multiple rows in C1DataGrid.

  You can check the behavior from the sample attached.(C1datagridFocusIssue.zip)

  We welcome your opinion in this regard for further consideration.

  Thanks & Regards,
  
  Aastha

  Hi,

  ok this is now a big problem for us. Because I want on Tab, that the focus away. And at your sample the focus is running through the rows.

  How can I change this? With TabNavigation=“Continue” it doesn’t works?

  Hi Patrick,

  You can handle C1DataGrid’s PreviewKeyDown event as shown in the following to shift the focus away from the DataGrid on pressing the ‘Tab’ key for the first time.

  Private Sub datagrid_PreviewKeyDown(ByVal sender As Object, ByVal e As KeyEventArgs)
      Dim grid = TryCast(sender, C1DataGrid)
      If e.Key = Key.Tab AndAlso grid.IsEditingRowsAllowed = False Then
          e.Handled = True
          Dim request As TraversalRequest = New TraversalRequest(FocusNavigationDirection.Next)
          request.Wrapped = True
          grid.MoveFocus(request)
      End If
  End Sub

  Please refer to the attached sample for full implementation.C1DataGridFocusIssue_ModVB.zip

  Thanks & Regards,

  Hi Aastha,

  thanks for your sample.
  
  I will be honest - for us it is very difficult to update now from 2018 to 2022. I know that we customized many things from C1.
  
  But that “normal” functions like this still not working any more is very bad.
  
  We also work with Graphical Tests and I think 70% after the C1 Update don’t work anymore.
  
  For us it is very difficult, how we can go on.
  
  Regards
