ASP.NET two forms on one page

I understand that ASP.NET only allows one form tag with runat="server" per page.

Suppose I have a search form on top of the page that is on every page.

How would I add another form, such as a contact us form? This would mean both forms are required to be on the same page, but of course I get an error in doing so. How do I get around this?

it may work if, you're other form is just a plain old form(no runat="server"), and none of the controls inside it can be server side controls then as well, so if you can handle that...also, the action must be a different page, since it will be more or less, a plain old vanilla html form...

    <form id="form2" action="contact.aspx">
        <input id="name" name="name" />
        <input id="phone" name="phone" />
        <input type="submit" value="Submit" />
    </form>
 
if this is not what you're after, maybe a little more of the why, may help someone help you with an elegant solution.
And what version of .NET?
in 2.0 you may be able to take advantage of cross page posting to do what you want with one form, and using a special button attribute that will cause it to submit to a different page...but again, a litle more info would help someone help you

The reason I want to use runat="server" is so that I can specify the link as ~/search.aspx and ~/admin/page.aspx

Then, the search form works from different directories because ASP.NET will handle the link correctly.

Also, the search form is on the master page. Other pages that inherit this page cannot have its own form. That's not good.

as far as I know, you just can't do two server side forms.

I think you could use ResolveUrl()...to build the correct link on the non-server side form, if that is all you're after...but with master pages this seems problematic at best...

but, if you are you using .NET 2.0, then you could use the search button in the same form, that will post to a search page instead of the default one, and since you're using this in the master page, it seems like a good way to go. <asp:Button Text="Search" PostBackUrl="~/search.aspx" .../>

and I think I answered my question, master pages = .net 2.0 :)

I did use ResolveUrl() and it worked as expected. Thanks. I still hope that in the future, we can have multiple and separate forms.
