Hi, I am having a problem getting clicked context menu item in TreeListView.

I always get null when calling the following method:

private RadTreeViewItem ClickedTreeViewItem

{

get

{

return this.TreeContextMenu.GetClickedElement<RadTreeViewItem>();

}

Please find xaml code below:

<telerik:RadTreeListView BorderThickness="0"

x:Name="TreeListView" Background="White"

ScrollViewer.HorizontalScrollBarVisibility="Auto"

ScrollViewer.VerticalScrollBarVisibility="Auto"

AutoGenerateColumns="false"

RowIsExpandedChanging="TreeListView_RowIsExpandedChanging"

RowIsExpandedChanged="TreeListView_RowIsExpandedChanged"

DataLoadMode="Synchronous"

SelectionChanged="TreeListView_SelectionChanged"

MouseRightButtonUp="TreeListView_MouseRightButtonUp">

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu

x:Name="TreeContextMenu"

Opened="TreeContextMenu_Opened"

ItemClick="TreeContextMenu_ItemClick">

<telerik:RadContextMenu.Items>

</telerik:RadContextMenu.Items>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

<telerik:RadTreeListView.Columns>

....

</telerik:RadTreeListView.Columns>

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}"/>

</telerik:RadTreeListView.ChildTableDefinitions>

</telerik:RadTreeListView>

Hello Alex,

If you are using the Q2 2010 version of RadControls or later you need to use the following code:

private RadTreeViewItem ClickedTreeViewItem  
{  
     get 
     {  
         return this.TreeContextMenu.GetClickedElement<TreeListViewRow>();  
     }  
}

Hope this helps.

All the best,
