Maybe I start from beginning.

On the page I have several updatepanels. Depending on what I click in the menu, the proper updatepanel is filled with ascx control.

Now in one of this ascx control I need to have the posibility to change dynamically controls in one fieldset when I press the button.

If I place there another update panel, when I try to update him, the parent update panel fires to.

So now I have webservice which returns the content and paste it in the proper place on the place. Please tell me, with the code example if it is possible, how to evaluate the javascript in this situation?

Hello Łukasz,

I believe the client-side method you are looking for is $telerik.evalScripts(parentElement);. This method evaluates all the client scripts present in the parentElement. If you do not have any RadControls present on the page, the $telerik static library can be referenced in the <ScriptManager/> as shown in the following sample:

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

<title></title>

<script type="text/javascript">

function EvalScripts()

{

$telerik.evalScripts($get("divScripts"));

}

</script>

</head>

<body>

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

<asp:ScriptManager ID="ScriptManager1" runat="server">

<Scripts>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

</Scripts>

</asp:ScriptManager>

<input type="button" value="EvalScripts" onclick="EvalScripts(); return false;" />

<div id="divScripts">

<script type="text/javascript">

alert("Scripts are evaluated");

</script>

</div>

</form>

</body>

</html>
