Can we use multiple forms in one application.
Showing error when we are using forms, we have given different ids for both the forms. Can anyone help me.

Yes, you can use multiple forms. What is the error you are getting?

Are you talking about a windows app, or a web app.
Im not an expert but I do beleive that you can only have one ASP.NET form with the runat="server" attribute per page (ie: PostBack Form).

I have divided the page into three parts.On the top i am using one user control,on left i am using one more application. I am including the left and top forms in the third one. But displaying error that Only one form can be used with the server tag and sometimes displays "The page could not have two 'page' directive".

This is the error i am getting.
"A page can have only one server-side Form tag.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: A page can have only one server-side Form tag.

How to rectify this error?

OK- you should be clearer... This is obviously an ASP.NET question (You should post in one of the ASP.NET forums.. rather than general)...

If I may, it seems your trying to create two ASP.NET Forms on the same ASP.NET page. This is not something that is supported in ASP.NET. A solution might be to use a frameset or iframe with different forms in each frame..

Yep, thought you were talking about a Windows app. What exactly are you trying to accomplish? In addition to Hal's suggestion, web forms can use panels to split the form into different segments.

I always forget panels! Doh!

But panels still don't let you have more than one form on the page.

lily- can you describe what you are trying to do? How are you "including" two forms on one page? Perhaps you are missing the point of user controls.

also without using usercontrols
(there is a simple way under some circumstances)
Have a look at
http://p2p.wrox.com/topic.asp?TOPIC_ID=17020
but still there is only one form
