RadTreeViewItem - event MouseLeftButtonDown or Up never fires

[James]

I bound the RadTreeViewItem.MouseLeftButtonDown to an event handler in code, but in debug I noticed the event never fires. I didn't use the RadTreeViewItem.Selected event because when a the item is selected, when use click the item again the Selected event don't fire - this is not I want, so I have to handle the MouseLeftButtonDown or Up events but... the two events never fire. Help!

(system: Silverlight 2 with Telerik 2009.1.526.1020)

Thanks
James

Hello James,

In order to accomplish the desired functionality you have to use MouseLeftButtonUp  event.

Please find attached a sample project that shows how to use MouseLeftButtonUp event with RadTreeView.

yes, the way in sample works for me. you use TreeView.OnMouseLeftButtonUp event and the SelectedItem to fulfill the same functionality that I wanted to use TreeViewItem.OnMouseLeftButtonUp event. So is that a bug about TreeViewItem.OnMouseLeftButtonUp event?

thanks

Hello James,

Please find attached a sample project that shows how to use  MouseLeftButtonUp event of RadTreeViewItem.

As you can see in the project  MouseLeftButtonUp  is working properly as expected.

I hope that this answers your question.

All the best,

From this sample, I wrote the following:

 

 

 

Private Sub MenuTreeView_MouseLeftButtonUp(sender As System.Object, e As System.Windows.Input.MouseButtonEventArgs)

 

 

 

    Dim treeview As Telerik.Windows.Controls.RadTreeView = TryCast(sender,Telerik.Windows.Controls.RadTreeView)

 

 

 

    Dim HeaderOfClickedItem As String

 

 

 

 

 

 

    HeaderOfClickedItem = treeview.SelectedItem.ToString

 

 

    MessageBox.Show(" we clicked on ... " + HeaderOfClickedItem)

 

 

 

End Sub

This enables me to acces the Header of the ClickedItem.  However, I need to access for instance the TAG attribute in doing something like

 

    TAGOfClickedItem = treeview.SelectedItem.TAG
howewer only the header is available with the .tostring  converter
 
Need help to find a way to do it

Hello Pierre-Paul,

The SelectedItem property returns object. Since the RadTreeView is not bound , you need to cast it to a RadTreeViewItem like so:

Dim item As Telerik.Windows.Controls.RadTreeViewItem = TryCast(Me.treeView.SelectedItem, Telerik.Windows.Controls.RadTreeViewItem)
Dim tag As Object = item.Tag
