从RadComboBox事件中获取GridViewRow

Question

我在 Telerik RadGridView 中有一个 RadComboBox 列，我想要做的是当您更改 RadComboBox 中的项目时，禁用< strong> GridViewRow RadComboBox ;为此，我需要获得 RadComboBox 的父级，但我尝试的不起作用

这是我的 RadGridView 代码：

     <telerik:RadGridView x:Name="dtgResumen" VerticalAlignment="Stretch" VerticalContentAlignment="Center" AutoGenerateColumns="False" HorizontalAlignment="Stretch" HorizontalContentAlignment="Center" FontSize="14" RowIndicatorVisibility="Collapsed" ShowGroupPanel="False" CanUserReorderColumns="False" CanUserResizeColumns="False" CanUserSortColumns="False" IsFilteringAllowed="False" GridLinesVisibility="Both" >
                <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn x:Name="colStatus" Header="STATUS" Width="1.3*" >
                    <telerik:GridViewDataColumn.HeaderCellStyle>
                        <Style TargetType="telerik:GridViewHeaderCell">
                            <Setter Property="HorizontalContentAlignment" Value="Center" />
                            <Setter Property="VerticalContentAlignment" Value="Center" />
                            <Setter Property="Background" Value="#538DD5" />
                            <Setter Property="FontWeight" Value="Bold" />
                            <Setter Property="Foreground" Value="Black" />
                            <Setter Property="FontSize" Value="12" />
                        </Style>
                    </telerik:GridViewDataColumn.HeaderCellStyle>
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <telerik:RadComboBox Name="comboBoxStatus" SelectedIndex="0" SelectionChanged="comboBox_SelectionChanged" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
                                <telerik:RadComboBox.Items>
                                    <telerik:RadComboBoxItem Content="Activa" Foreground="Green" />
                                    <telerik:RadComboBoxItem Content="Cancelada" Foreground="Red" />
                                </telerik:RadComboBox.Items>
                            </telerik:RadComboBox>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>
           </telerik:RadGridView.Columns>
        </telerik:RadGridView>

这是事件中的代码：

private void comboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    var combo = sender as RadComboBox;

    var row = FindParent<GridViewRow>(combo);
}

这是FindParent代码：

    public static Parent FindParent<Parent>(DependencyObject child) where Parent : DependencyObject
    {
        DependencyObject parentObject = child;

        //We are not dealing with Visual, so either we need to fnd parent or
        //get Visual to get parent from Parent Heirarchy.
        while (!((parentObject is System.Windows.Media.Visual) || (parentObject is System.Windows.Media.Media3D.Visual3D)))
        {
            if (parentObject is Parent || parentObject == null)
                return parentObject as Parent;
            else
                parentObject = (parentObject as FrameworkContentElement).Parent;
        }

        //We have not found parent yet , and we have now visual to work with.
        parentObject = VisualTreeHelper.GetParent(parentObject);

        //check if the parent matches the type we're looking for
        if (parentObject is Parent || parentObject == null)
            return parentObject as Parent;
        else
            //use recursion to proceed with next level
            return FindParent<Parent>(parentObject);
    }

我也试过这个，但它不起作用：

        var combo = sender as RadComboBox;
        var row = combo.ParentOfType<GridViewRow>();
