Vijay,
I've moved this to the appropriate section (ASP.NET => Controls), for your information.
Are you able to see the styles in Design of the pages?
Do you have an ig_res folder in the project?
Can you share a project that has this issue so I can determine if this is something in the project or on the machine?
Apart from that, what you need is - the assemblies that you are going to reference in the project to appear in the GAC of the machine and you also need to make sure that in the project you are referencing exactly them and not the ones from the bin folder or some other folder.
If you experience this issue in run-time, that's another sort of issue, so please see if you can answer the above questions.
Thank you in advance!
Thanks Boris.
This works fine now, Appreciates the quick reply :-).
