I have a 2 treeviews lets say tree1 and tree2.
tree1 has checkbox nodes
I drag and drop the checked nodes from tree1 to tree2.
On tree1_nodedrop, trying to read those checkednodes using Tree1.CheckedNodes() and it is always returning 0.
Earlier it used to work, i'm not sure whether is stop working after SP1 installation or VS2012 installation.

Telerik Current Version: 2012.2.724.40 (2012 Q2 SP1)
Code Editor: Visual Studio 2010
Framework: 4.0
Tree1 ASPX  Code:
<telerik:RadTreeView ID="tree1" runat="server" Skin="Windows7" DataFieldID="ID"

 

 

 

 

DataFieldParentID="ParentID" DataTextField="NodeText" EnableDragAndDrop="true"

 

 

 

 

CheckBoxes="true" CheckChildNodes="true" DataValueField="ValueID">

Code Behind:
Private Sub tree1_NodeDrop(sender As Object, e As Telerik.Web.UI.RadTreeNodeDragDropEventArgs) Handles tree1.NodeDrop
For Each node As RadTreeNode In tree1.CheckedNodes
// do something

 

 

 

Next

 

 

 

End Sub

What am i missing here?

Hi Phani,

I have performed some tests and it works as expected at my end. In addition, I have recorded a video, demonstrating the behavior at my end. Please let me know if I am missing something.

Its my bad. I'm using this in a user control and the IsPostback check is commented somehow, hence it is binding again on every postback. Never mind, thanks for your help.
