Vista - ASP namespace strong type access for dynamically loaded user control

permalink · 04-07-2008

ASP namespace strong type access for dynamically loaded user control
(web application, not web site)

I have a user control in a web application which I dynamically load
from an aspx page as follows:
UserControl ctl = Page.LoadControl("./User Controls/
MailForwardingGrid2.ascx") as UserControl;
form1.Controls.Add(ctl);

This works fine.

I have added 2 properties to the user control and would like to load
the strong type version of the user control in order to set the new

parameters at runtime. I would like to do something like the
following:
ASP.usercontrols_MailForwardingGrid2_ascx ctrl =
(ASP.usercontrols_MailForwardingGrid2_ascx)Page.LoadControl("./User

Controls/MailForwardingGrid2.ascx");
ctrl.SourceTypeID = Int32.Parse(context);
ctrl.SourceID = id;

Unfortunately, the ASP namespace is not showing my user control (the
ASP namespace is not showing up at all).

I have tried "<%@ Register ... " and "<%@ Reference ... " to no avail
as follows:

<%@ Register Src="User Controls/MailForwardingGrid2.ascx"
TagName="MailForwardingGrid2"
TagPrefix="uc1" %>
<%@ Reference Control="User Controls/MailForwardingGrid2.ascx" %>

I access user controls through the ASP namespace from web sites all
the time but the current failure is from a web application.

Advice?

-------------------------------------
DETAILS:
Here is the page from which I am attempting to access the user
control...

<%@ Page Language="C#" AutoEventWireup="true"
CodeBehind="DisplayForm.aspx.cs"

TagPrefix="uc1" %>

<%@ Reference Control="User Controls/MailForwardingGrid2.ascx" %>

Here is the body of the user control:

//objList = MailForwardInfoList.GetMailForwardInfoList(1,
"p000196");
objList =
MailForwardInfoList.GetMailForwardInfoList(SourceTypeID, SourceID);
gvMailForwardingTemplate.DataSource = objList;
gvMailForwardingTemplate.KeyFieldName = "InvoiceId";
gvMailForwardingTemplate.DataBind();
}

private int sourceTypeID;
public int SourceTypeID
{
get { return sourceTypeID; }
set { sourceTypeID = value; }
}

private string sourceID;
public string SourceID
{
get { return sourceID; }
set { sourceID = value; }
}

//

//}
}
