Hello,

Infragistics ASP.NET controls follow the same logic as standard ASP.NET controls and you can debug them just the way you debug normal code. For information on debugging in Visual Studio .NET, you can check out this link:

For debugging client-side code, I recommend installing a browser plugin tool like IE Web Developer Toolbar or FireFox FireBug.
