Hi...
Please read the following.
The following sections cover HTML and Web server controls. Frequently, the question
arises: which one should I use? Here is some guidance that can help you choose
the proper control type.
Consider using the HTML server controls when any of the following conditions exist:
■ You are migrating existing ASP pages to ASP.NET.
■ The control needs to have custom client-side JavaScript attached to the control’s
events.
■ The Web page has lots of client-side JavaScript and that is referencing the control.
In all other cases, you should consider using the more powerful Web server controls.
