Asp.NET: How to install CoolControls?

Question

I cannot seem to install this control. I use Visual Studi 2012, I downloaded the dll. I put it in my project folder, I added a reference of it, and I added this line to my aspx site:

<%@ Register Assembly="IdeaSparx.CoolControls.Web" Namespace="IdeaSparx.CoolControls.Web" TagPrefix="cc" %>

In my aspx site, I add the control:

    <cc:CoolGridView ID="CoolGridView1" runat="server" Height="400px" Width="600px">
 </cc:CoolGridView>

But when I add a control, it says there was an error rendering this control. What can be the problem?

Answer 1

Okay I found the problem, it was my fault, I had to connect it to a datasource and it works.
