getSelectedNode in javascript didn't fire
posted

I use the ultrawebTree methods (CSOM) getSelectedNode, but nothings happen. This is my function:

 

function changeImageSelectionne(treeView)

{

 

          var node = treeView.getSelectedNode();

 

}

 

 

In my ultrawebTree tag:

<ClientSideEvents NodeClick="changeImageSelectionne" />

    HI ,

    I am not sure where you created your treeview object.

     also  make sure the webtree's selectable property is set to "True"

     I could not reproduce. I created a sample page - I tested it and it works.

     aspx page:
