Product	RadContextMenu for WPF

Description

Select the RadTreeViewItem that was clicked when the RadContextMenu opens.

Solution

Handle the RadContextMenu Opened event, get the clicked RadTreeViewItem, and assign it to the RadTreeView.SelectedItem property.

This tutorial will show you how to select the item that was clicked, while opening the RadContextMenu. In order to achieve this, you have to do the following things:

Handle the Opened event of the RadContextMenu
Get an instance of the clicked RadTreeViewItem
Set the SelectedItem of the RadTreeView

Before starting, here is a sample RadTreeView with a sample RadContextMenu attached.

Attach RadContextMenu to RadTreeView

XAML

<telerik:RadTreeView xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" x:Name="radTreeView">
    <telerik:RadContextMenu.ContextMenu>
        <telerik:RadContextMenu x:Name="radContextMenu">
            <telerik:RadMenuItem Header="Menu Option 1" />
            <telerik:RadMenuItem Header="Menu Option 2" />
            <telerik:RadMenuItem Header="Menu Option 3" />
        </telerik:RadContextMenu>
    </telerik:RadContextMenu.ContextMenu>
    <telerik:RadTreeViewItem Header="Category1">
        <telerik:RadTreeViewItem Header="Product1" />
        <telerik:RadTreeViewItem Header="Product2" />
        <telerik:RadTreeViewItem Header="Product3" />
    </telerik:RadTreeViewItem>
    <telerik:RadTreeViewItem Header="Category2" />
    <telerik:RadTreeViewItem Header="Category3" />
    <telerik:RadTreeViewItem Header="Category4">
        <telerik:RadTreeViewItem Header="Product A" />
        <telerik:RadTreeViewItem Header="Product B" />
        <telerik:RadTreeViewItem Header="Product C" />
    </telerik:RadTreeViewItem>
    <telerik:RadTreeViewItem Header="Category5" />
</telerik:RadTreeView>

To handle the Opened event attach an event handler to it.

Handle the RadContextMenu Opened Event

XAML

<telerik:RadContextMenu xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                        x:Name="radContextMenu"
                        Opened="RadContextMenu_Opened">
    <telerik:RadMenuItem Header="Menu Option 1" />
    <telerik:RadMenuItem Header="Menu Option 2" />
    <telerik:RadMenuItem Header="Menu Option 3" />
</telerik:RadContextMenu>

Define the Opened Event Handler in C#

private void RadContextMenu_Opened( object sender, RoutedEventArgs e )
{
}

In it get the instance of the clicked RadTreeViewItem by calling the GetClickedElement<T>() method of the RadContextMenu.

Get the Clicked RadTreeViewItem in C#

private void RadContextMenu_Opened(object sender, RoutedEventArgs e)
{
    RadTreeViewItem item = this.radContextMenu.GetClickedElement<RadTreeViewItem>();
}

The last thing to do is to set the SelectedItem property of the RadTreeView to the instance of the RadTreeView item that has been clicked.

If you are having a dynamic data scenario, where the RadTreeView is bound to a collection, you have to set the SelectedItem property to the DataContext of the clicked RadTreeViewItem.

Select the Clicked Item in C#

private void RadContextMenu_Opened(object sender, RoutedEventArgs e)
{
    RadTreeViewItem item = this.radContextMenu.GetClickedElement<RadTreeViewItem>();
    if (item != null)
    {
        this.radTreeView.SelectedItem = item;
    }
}

The selected item is now available through the SelectedItem property of the tree view.
