Unable to expand a branch on client side

[AK]

Hi,

I have a Treeview control nested inside a RadComboBox. The Expand mode is ServerSideCallBack. I want to select a node in the tree through javascript. But the branch for that node is not expanded. I know all the ancestors of that node. So I tried to expand that branch starting from the top level parent. I use the following piece of code to expand the parent.

if

 

(parentNode != null && !parentNode.get_expanded()) {

 

_treeFirst.trackChanges();

parentNode.set_expandMode(Telerik.Web.UI.TreeNodeExpandMode.ServerSideCallBack);

parentNode.set_expanded(

true);

 

_treeFirst.commitChanges();

}

This expands only the second level parent (the first level parent is already there and expanded on the initial load). I am not able to expand further from the second level. Please help!!

Hi AK,

Could you please, try expanding the new level on clientNodePopulated event instead synchronously?

Hope this is going to help you!
