I had to add a new user control to an existing project that already contained a lot of them, and wondered why mine was not rendering. Turns out you can also specify this in Web.config, under configuration, system.web, pages, like this:

<controls>
    <add tagPrefix="cc1" tagName="ctrl" src="~/UserControls/ctrl.ascx" />

...which will register the control for the whole project, so you don't have to specify this on every page. Useful for controls that are heavily reused.

Make sure you haven't set visible="false" on a panel or div containing your control.

That would've saved me a good hour.

IF you have created custom control then you should add reference of the dll of your custom control ( from choose items from ToolBox of Visual Studio). and then Use the following tag in the page :

<%@ Register assembly="proj" namespace="proj.UserControls" tagprefix="cc1" %>

If you created User Control then add the following line in your page:

<%@ Register src="~/UserControls/ctrl.ascx" TagName="ctrl" tagprefix="cc1" %>

Change:-

<%@ Register assembly="proj" namespace="proj.UserControls" tagprefix="cc1" %>

To

<%@ Register TagPrefix="cc1" TagName="ctrl" Src="/path/to/ctrl.ascx" %>

You're missing TagName, which represents the text following the colon in the control declaration. You're also not telling the engine where to find the source file ( Src attribute ). Change /path/to to represent the path from root to your control.

instead of 

<%@ Register assembly="proj" namespace="proj.UserControls" tagprefix="cc1" %>

use 

 <%@ Register  src="~/UserControls/ctrl.ascx"  TagName="ctrl" tagprefix="cc1" %>
