private void containsCol(object sender, RoutedEventArgs e)
{
    if (grid1.ColumnDefinitions.Contains(colDef1))
    {
        tp3.Text = "Grid Contains ColumnDefinition colDef1";
    }
    else
    {
        tp3.Text = "Grid Does Not Contain ColumnDefinition colDef1";
    }
}

Private Sub containsCol(ByVal sender As Object, ByVal e As RoutedEventArgs)
    If (grid1.ColumnDefinitions.Contains(colDef1)) Then
        tp3.Text = "Grid Contains ColumnDefinition colDef1"
    Else
        tp3.Text = "Grid Does Not Contain ColumnDefinition colDef1"
    End If
End Sub
