RadContextMenu in RadTreeListView

[Adriano]

Hi, is it possible to attach a RadContextMenu on a RadTreeListView? Because we tried to follow the instructions of the RadTreeView sample but with no success.

Best regards

Hi Adriano,

What example are you following?

If the context menu there is part of the ItemTemplate of the TreeView it will indeed not work for the TreeList because the ItemTemplate in the TreeList appears as a details view for the items.

You can assign one context menu for the whole TreeList and find the item that has been clicked in the Opened event:

private void OnMenuOpened(object sender, RoutedEventArgs e)
{
    var row = contextMenu.GetClickedElement<RadTreeListViewItem>();
    if (row != null)
    {
        var dataItem = row.Item;
    }
}

And the xaml:

<telerikNavigation:RadContextMenu.ContextMenu>
    <telerikNavigation:RadContextMenu x:Name="contextMenu" Opened="OnMenuOpened">
        <telerikNavigation:RadMenuItem Header="Action 1" />
        <telerikNavigation:RadMenuItem Header="Action 2"/>
    </telerikNavigation:RadContextMenu>
</telerikNavigation:RadContextMenu.ContextMenu>

Hopefully this will help you,

Best wishes,
