why did i get the error unable to cast object of type 'Telerik.Web.UI.RadTreeview' to type 'Telerik.Web.UI.controlitemcontainer'

[John]

I added the Radtreeview to asp:content and got this error msg. But if I added the RadTreeview to the following:

<

 

body>

 

 

<form id="form1" runat="server">

 

 

<div>

 

 

 

<telerik:RadTreeView ID="RadTreeView1" runat="server">

 

 

</telerik:RadTreeView>

 

 

 

</div>

 

 

</form>

 

</

 

body>

no error message. Did anybody have similar issue before? thanks

Hi John,

The exception that you are getting is a very general one. It indicates that you can not cast an object from one type to another type. Please take a look at the following post where you can fin more information related to similar issues:
