[Solved] Is not possible what I whant? Template that contains Treeview in Combo

[Fabio Laserra]

Hello,
I have tried to inser in a template contained in a RadGrid a RadCombo that shows a TreeView. It works only if I don't use ajax (so with traditional postbacks). It I insert the grid in a panelupdate, this combo does not work. Below you can find the code I used. Can anyone suggest me a solution? The problem is in javascript code

Thank you

Hello Fabio,

Could you please try wrapping the javascript code in a RadScriptBlock and see if it makes any difference?
If the problem persists, I suggest that you handle the grid ItemDataBound event and there register the client scripts through the ScriptManager.RegisterStartupScript() method.

Give it a try and let me know if you need further assistance.
