Tom,

I should have read the title of your message more carefully, it does say "client side". Sorry for missing it.

I have done one project in ASP.NET where I was using client side script. I am not sure it was as sophisticated as what you are trying to do. But I will look it up and if I see that something there may lead to a solution for you, I will let you know.

BTW, when I started with ASP.NET (and I am still at the starting line <g>), I was doing both VB and C#, not knowing which way to go.
So I guess you are on the right track and fortunately <g>, you only have to choose between two options <g>.

>Thank you for your response by the way. I do not ask many questions and I receive even fewer responses! :) It is always nice to know there is someone out there that tried to help. There is a lot to learn and we are still arguing which language to use – VB.NET or C sharp. I am learning both! First I define what I want to do and use VB.NET and then do it is C sharp.
