Examples

В следующем примере показано, как использовать метод Contains, чтобы определить, существует ли RowDefinition в RowDefinitionCollection.The following example demonstrates how to use the Contains method to determine whether a RowDefinition exists in a RowDefinitionCollection.

private void containsRow(object sender, RoutedEventArgs e)
{
    if (grid1.RowDefinitions.Contains(rowDef1))
    {
        tp2.Text = "Grid Contains RowDefinition rowDef1";
    }
    else
    {
        tp2.Text = "Grid Does Not Contain RowDefinition rowDef1";
    }
}
Private Sub containsRow(ByVal sender As Object, ByVal e As RoutedEventArgs)
    If (grid1.RowDefinitions.Contains(rowDef1)) Then
        tp2.Text = "Grid Contains RowDefinition rowDef1"
    Else
        tp2.Text = "Grid Does Not Contain RowDefinition rowDef1"
    End If
End Sub
