[Solved] DragNDrop Between Grids In Different User Controls

[Kevin]

I'm trying to adapt the drag and drop grid sample (with pending orders and shipped orders) to my particular situation and am having some difficulty.

I can't the correct syntax for how to reference each grid's clientid since it is in a user control.  I'm trying as follows:
uc2_RadGrid1.ClientID

But that is not correct.  What is the correct syntax in the javascript below for correctly grabbing a reference to a grid's clientID when it is inside a user control?

Thx!

In my situation, I have each grid in a different user control along with some other items on the screen.  My two user controls each have a RadGri1 grid in them, and they are defined in the page as:

<%@ Register src="ContactGrid.ascx" tagname="ContactGrid" tagprefix="uc2" %>
<%@ Register src="ContactSelected.ascx" tagname="ContactSelected" tagprefix="uc4" %>

and the script block taken from the sample is:

    <telerik:RadScriptBlock runat="server" ID="scriptBlock">

        <script type="text/javascript">
            <!--

I got it.  I need to reference them like this:

<%=ContactGrid.FindControl("RadGrid1").ClientID %>

and this:

<%=ContactSelected.FindControl("RadGrid1").ClientID %>
