Examples

The following example demonstrates how to use the IndexOf method to determine the index position of a ColumnDefinition within a ColumnDefinitionCollection.

private void insertColAt(object sender, RoutedEventArgs e)
{
    colDef1 = new ColumnDefinition();
    grid1.ColumnDefinitions.Insert(grid1.ColumnDefinitions.Count, colDef1);
    tp2.Text = "ColumnDefinition added at index position " + grid1.ColumnDefinitions.IndexOf(colDef1).ToString();
}
Private Sub insertColAt(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim colDef1 As New ColumnDefinition()
    grid1.ColumnDefinitions.Insert(grid1.ColumnDefinitions.Count, colDef1)
    tp2.Text = "ColumnDefinition added at index position " + grid1.ColumnDefinitions.IndexOf(colDef1).ToString()
End Sub
