Hi there,
You can add something like this to the system.web element in web.config:
Code:
<pages>
<controls>
<add tagPrefix="YourPrefix" tagName="ControlName" src="~/Controls/ControlName.ascx"/>
</controls>
</pages>
You can then use the control like this:
Code:
<YourPrefix:ControlName ID="ControlName1" runat="server" />
Hope this helps,
Imar
