Collapsing Rad Drop Down Tree nodes except the clicked node

[Pradeep]

Hi,

I have rad drop down tree as below. When I click on one node in the drop down tree I am able to see the parent node getting expanded by using below client side script and if i click on other node the script executes and node gets expanded. Is there a way I can collapse all other nodes except the current clicked node?

 

<telerik:RadDropDownTree RenderMode="Lightweight" ID="OfficeDropDownPrgFilter" runat="server" Width="500px"
                   ExpandNodeOnSingleClick="true"  AutoPostBack="true" OnClientEntryAdded="OnClientEntryAdded1" 
                    EnableFiltering="true" OnEntryAdded="OfficeDropDownPrgFilter_EntryAdded"> 
                    <DropDownSettings OpenDropDownOnLoad="true"  />
                    <FilterSettings Highlight="Matches" Filter="Contains" EmptyMessage="Type here to filter" />
                </telerik:RadDropDownTree> 

 

function OnClientEntryAdded1(sender, args) {
var path = args.get_entry()._fullPath;
var item = sender.get_embeddedTree().findNodeByText(args.get_entry().get_text());
var node = item.get_parent();
node.expand();
}
