RadTreeView obj is null in JavaScript

[Prasad]

Hi,
I am getting obj for radtreeview in javascript by using document.getElementById(...) but same thing is not getting by using $find(..).
If i get obj form the documnet class i am not able to get nodes form the tree obj... My code is looks like

<telerik:RadScriptBlock ID="rcb" runat="server">

 <script type="text/javascript">

 debugger;

 

Generate_WhereCondition1();

 

</script>

 -- Generate_WhereCondition1() logic is follows;
var tree = $find("<%= tvfltview.ClientID %>"); // here i am getting null -- type 1

 

 if(tree==null)

tree=document.getElementById("<%= tvfltview.ClientID %>"); // here i am getting obj -- type 2

 

</telerik:RadScriptBlock>

but i can getting error for tree.get_nodes(); from type 2

Hello,

You are retrieving a null value for the tree object, because at this moment our RadTreeView client-side object is not initialized yet. I would suggest you to subscribe to some of RadTreeView client-side events to find and manipulate  the RadTreeView client-side object. Please review our RadTreeView client-side programming section in order to find detailed information about its available properties and methods.
The document method getElementById is returning a DOM element which is different than the RadTreeView client-side object. This is the reason why that object does not offer all methods and properties that are available by using our RadTreeView client-side object. 

Kind regards,
