Examples

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

private void insertRowAt(object sender, RoutedEventArgs e)
{
    rowDef1 = new RowDefinition();
    grid1.RowDefinitions.Insert(grid1.RowDefinitions.Count, rowDef1);
    tp1.Text = "RowDefinition added at index position " + grid1.RowDefinitions.IndexOf(rowDef1).ToString();
}

Private Sub insertRowAt(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim rowDef1 As New RowDefinition
    grid1.RowDefinitions.Insert(grid1.RowDefinitions.Count, rowDef1)
    tp1.Text = "RowDefinition added at index position " + grid1.RowDefinitions.IndexOf(rowDef1).ToString()
End Sub
