Hi,

We have an aspx page where we are using frameset. In first frame we've an user control containing radtreeview (eg RadTree1) and depending on selected node we are loading another aspx page in second frame.

The aspx page we are loading in second frame has an user control "usercontrol.ascx" which contains another radtreeview (eg RadTree2). This is a load on demand tree

We need to disable certain nodes of the second radtree while they are being created, ie. on load of the radtree, some nodes should appear to be disabled. This has to be done on the client side.

My problem is that when we try to find this second radtreeview (eg RadTree2) in "usercontrol.ascx", on page load, we get null in return.

We tried to to use $find function but it is also not working.

Kindly reply asap

Regards,
SK

Hi Shweta,

Could you please paste here the code you are using to find RadTreeView? Keep in mind that you need to access the window object of the required frame in order to find ASP.NET Ajax components using the $find routine:

window.frames['frameName'].$find("userControl1_RadTreeView1");
