The following example demonstrates how to use the RemoveAt method to remove a ColumnDefinition to a ColumnDefinitionCollection at a specific index position.


private void removeCol(object sender, RoutedEventArgs e)
{
    if (grid1.ColumnDefinitions.Count <= 0)
    {
        tp1.Text = "No More Columns to Remove!";
    }
    else
    {
        grid1.ColumnDefinitions.RemoveAt(0);
    }
}
