No need to run here and there. If you are looking for some free ASP.NET control. Get it from - http://www.codeproject.com/KB/selection/ColorPicker.aspx
Download the CustomControl and compile it. You will get the DLL
Using DLL
1. <%@ Register Assembly="CustomControls" Namespace="CustomControls" TagPrefix="cc1" %>
2. <cc1:colorpicker id="ColorPicker1" runat="server"></cc1:colorpicker>
3. To get the color - ColorPicker1.Color
Thanks to Viktar Karpach to putting it on this site. I had tried 10 controls and end up using this one.
