Unknown server tag error

In the case of an error of "Unknown server tag" format regarding AjaxControlToolkit, you should add the first line of code marked in the figure to the web.config as follows:

<add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit"/>







With this trick, you not only solve your problem, but also you won't have to write

<%@ Register Assembly="AjaxControlToolkit" TagPrefix="cc1" Namespace="AjaxControlToolkit" %>

anymore to each page to use Ajax elements.

Change MasterPage at runtime

Let's say that we want to change the masterpage file of a page, when the user is logged in.
You can do the following:

In the code side of the page, we can write the following code in the PreInit event, that we will define:

protected void Page_PreInit(object sender, EventArgs e) {
try
{
userID = Int32.Parse(Session["userID"].ToString());
this.MasterPageFile = "~/NewMasterPage.master";
}
catch
{
;
}
}
