Summary

All the keyboard behavior of the grid is determined by the KeyActionMappings collection. This collection can be modified to alter the keyboard behavor. By default, the collection already contains definitions for Tab key behavior. So in order to make the grid respond to Enter, all that must be done is to go through the KeyActionMappings and add a corresponding mapping for the Enter key that matches each Tab key entry.

Additional Information

The following sample code loops through all the KeyActionMappings in the grid. Whenever if finds a KeyActionMapping for the Tab key, it creates a copy of the mapping that applies to the Enter key, instead of tab and adds it to the collection.

In VB.NET:

Private Sub MakeEnterActLikeTab(ByVal Grid As Infragistics.Win.UltraWinGrid.UltraGrid)
    Dim newKam As Infragistics.Win.UltraWinGrid.GridKeyActionMapping
    For Each ugkam As Infragistics.Win.UltraWinGrid.GridKeyActionMapping In Grid.KeyActionMappings
        If ugKam.KeyCode = Keys.Tab Then
            newKam = New Infragistics.Win.UltraWinGrid.GridKeyActionMapping(Keys.Enter, ugKam.ActionCode, ugKam.StateDisallowed, ugKam.StateRequired, ugKam.SpecialKeysDisallowed, ugKam.SpecialKeysRequired)
            Grid.KeyActionMappings.Add(newKam)
        End If
    Next
End Sub

In C#:

private void MakeEnterActLikeTab(Infragistics.Win.UltraWinGrid.UltraGrid Grid)
{
    Infragistics.Win.UltraWinGrid.GridKeyActionMapping newKam;

    foreach (Infragistics.Win.UltraWinGrid.GridKeyActionMapping ugKam in Grid.KeyActionMappings)
    {
        if (ugKam.KeyCode == Keys.Tab)
        {
            newKam = new Infragistics.Win.UltraWinGrid.GridKeyActionMapping(Keys.Enter, ugKam.ActionCode, ugKam.StateDisallowed, ugKam.StateRequired, ugKam.SpecialKeysDisallowed, ugKam.SpecialKeysRequired);
            Grid.KeyActionMappings.Add(newKam);
        }
    }
}
