Dynamically adding in User Controls

tshad

Is there a way to dynamically add in User Controls where I would get the
name from a session variable:

If I have the following code:
************************************************** ****************************
<%@ Page Language="VB" trace="false" debug="true" ContentType="text/html"
ResponseEncoding="iso-8859-1" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<%@ Register TagPrefix="fts" TagName="Navigate" Src="sdhcNavigate.ascx" %>
<%@ Register TagPrefix="fts" TagName="Navigate" Src="ft2Navigate.ascx" %>
<%@ Register TagPrefix="fts" TagName="Navigate" Src="sbNavigate.ascx" %>

<html>
<head>
<title>:: Staffing Workshop ::</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<body id="myBody" runat="server">
<form id="addForm" runat="server">

<fts:Navigate runat="Server"/>

</form>
</body>
</html>
************************************************** ******************************

I would like to change it so that I can do something like changing the Src
attribute of the Register statement based on a session variable.

For example if my session variable "company" was either "sdhcNavigate.ascx",
"ft2Navigate.ascx" or "sbNavigate.ascx"

************************************************** ****************************
<%@ Page Language="VB" trace="false" debug="true" ContentType="text/html"
ResponseEncoding="iso-8859-1" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<%@ Register TagPrefix="fts" TagName="Navigate" Src="" %>
<script runat="server">
Sub Page_Load(sender as Object, e as EventArgs)
if not IsPostBack

Set the Src of the control here (or maybe in the html area)

end if
</script
<html>
<head>
<title>:: Staffing Workshop ::</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<body id="myBody" runat="server">
<form id="addForm" runat="server">

<fts:Navigate runat="Server"/>

</form>
</body>
</html>
************************************************** ******************************

I would use this in all my 50 pages to load the control based on the
company.

Thanks,

Tom

Hi,

The way I do this:

Don't put any register tag prefixes.
Put a placeholder where you want the control to appear.
In your code behind load the control you want, i.e.:

Dim MyControl As New Control
MyControl = LoadControl("TravelClinicSearch.ascx")
plcDatabases.Controls.Add(MyControl)

Where plcDatabases is the name of the placeholder. Obviously, the
control name can be a variable.

Hope this helps.

That was what I was looking for.

I wanted to be able to load a control depending on settings in my session
variables and this would allow me to do that.

Thanks,

Tom
