Hi –

 I am using telerik Rad Controls in a .NET 2.0 application. There is an ASP.net page in application which consists of below controls.

<%@ Register Assembly="RadPanelbar" Namespace="Telerik.WebControls" TagPrefix="radp" %>

<%@ Register Assembly="RadMenu" Namespace="Telerik.WebControls" TagPrefix="radm" %>

<%@ Register Assembly="RadMultiPage" Namespace="Telerik.WebControls" TagPrefix="radMP" %>

<%@ Register Assembly="RadTabStrip" Namespace="Telerik.WebControls" TagPrefix="radTS" %>

<%@ Register TagPrefix="radA" Namespace="Telerik.WebControls" Assembly="RadAjax.Net2" %>

RadPanelbar.dll – version 3.5.2.0

RadMenu.dll – version 3.6.2.0

RadMultiPage.dll – version 1.5.2.0

RadTabStrip.dll – version 2.5.2.0

RadAjax.Net2.dll – version 1.8.4.0

The page contains a menu with few tabs. For each tab an asp.net web user control (.ascx) is loaded. The web user controls contains rad data grids and other rad & standard VS controls where data is fetched from a database.  A Rad Ajax Manager is placed in the page to perform some validations. Rad Ajax Manager and Rad Ajax Panel is placed inside Web user controls to implement ajax functionality.

When loading this page a JavaScript error is thrown as “ ‘parentNode’ is null or not an object” for RadMenu_Global.js.  The script error is thrown in RadMenu_Global.js. This does not occur all the time and it happens so rarely and because of that reason i have not been able to reproduce the issue to identify the problem.

Any idea’s to resolve this issue?

<telerik:GridTemplateColumn HeaderText="mycol" UniqueName ="temp1">

<ItemTemplate>

<asp:DropDownList ID="ddl" runat="server"></asp:DropDownList>

</ItemTemplate>

</telerik:GridTemplateColumn>

(e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

DropDownList ddl1 = (DropDownList)item["temp1"].FindControl("ddl");

ddl1.DataSourceID = ?

ddl1.DataTextField =?

ddl1.DataValueField =?
ddl1.DataBind();

}
