Referencing User Control In Some Other User Control

hi,
I have two user controls namely CanvasGrid.ascx and GridUtility.ascx. CanvasGrid.ascx is just a container for displaying GridView control in a placedholder GridPH. I want to get the checked rows from GridView control of CanvasGrid.ascx and do tagging against specific name selected from the TagDropDownList of GridUtility.ascx. But the problem is that I am not geting the reference of GridView as it is coming null everytime even when I am using FindControl() to find the GridView control on the page. GridUtility.ascx is a part of CanvasGrid.ascx and it is placed in a placeholder GridUtilityPH using LoadControl() at pageLoad of CanvasGrid.ascx
 Awaiting for reply
Thanks 
Abhijit

do you have explicit reference of the usercontrol you are dynamically trying to load?

CanvasGrid.ascx has a explicit reference of GridUtility UserControl but other way round is not true
CanvasGrid.ascx Code snippet
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="CanvasGrid.ascx.cs" Inherits="Panels_CanvasGrid" %> 
<%@ Register Src="GridUtility.ascx" TagName="GridUtility" TagPrefix="uc1" %>
 
GridUtlity.ascx code snippet

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="GridUtility.ascx.cs" Inherits="Panels_GridUtility" %>

Hi Abhijit,
Have you try the following code with loadcontrol method in your web form page.
protected void Page_Load(object sender, EventArgs e)
    {
        Control ctl = Page.LoadControl("~/CanvasGrid.ascx ");
        Control gridview_control = ctl.FindControl("Gridview_id");
        Session["GridView"] = gridview_control;
}
The code snippet above put the gridview_control into a session object; therefore, you can access 
the gridview control by the session object in another user control.
Hope this Information is helpful!

I devised a solution to make two usercontrol interact with each other.
