Background color of group header row

[Lou]

I have implemented custom grouping for a GridView and would like to change the group header background color for some groups based on the grouped rows.

How would I do that?

Never mind - I found the documentation for how to do this. Here's the code I used:

    If TypeOf e.CellElement.RowInfo Is GridViewGroupRowInfo Then
      If (condition) Then
        e.CellElement.RowElement.BackColor = Color.Red
        e.CellElement.RowElement.GradientStyle = GradientStyles.Solid
        e.CellElement.RowElement.DrawFill = True
      Else
        e.CellElement.RowElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local)
        e.CellElement.RowElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local)
        e.CellElement.RowElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local)
      End If
    End If
