Problem in getting updated node text in code behind

[Balaji]

Hi Telerik,

I am using ajax rad tree view in my project. And we have the requirement of node drag & drop functionality.
And in OnClientNodeDropping event  I have written one function to change the source node text. After that I need to get the updated text at server side. But I am not getting the updated text from the source node at code behind.

Sample code:
 
<telerik:RadTreeView ID="RadTreeView1" MultipleSelect="false" OnNodeDrop="RadTreeView1_HandleDrop" EnableDragAndDropBetweenNodes="true"  EnableDragAndDrop="true" 

 OnClientNodeDropping="onNodeDropping"  EnableViewState="true" runat="server">

 </telerik:RadTreeView>
---------------------------------------------------
function onNodeDropping(sender, args)

 {

 args.get_sourceNode().set_text(args.get_sourceNode().get_text() +

"_" + args.get_sourceNode().get_value());

   }
---------------------------------------------------
In the below event I need to access the updated text. But When I try access the sourceNode.text, it is giving old text only
 
Protected Sub RadTreeView1_HandleDrop(ByVal sender As Object, ByVal e As RadTreeNodeDragDropEventArgs) 

    Dim sourceNode As RadTreeNode = e.SourceDragNode

    Dim destNode As RadTreeNode = e.DestDragNode

End Sub

Please help me to get the updated text in code behind.
 

Thanks in advance

Hello Balaji,

You should use trackChanges() and commitChanges() methods of the treeview client-side object in order to preserve changes made to the treeview at the server, this is explained here.

Hi Yana,

The example you given is very helpfull. Thanks for that.

Now, I can able to get the updated text in the code behind. But, Is there any attribute to indicate that the text is changed ?

Thanks in advance,
