hi,
In your web page have two form like this
<pre lang="c#"><pre><html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title></head>
<body>
<form id="form1" runat="server">
<div> </div>
</form>
<form id="form2" runat="server">
<div> </div>
</form>
</body>
</html></pre></pre>So you are getting "A page can have only one server-side Form tag. " error message so just remove one runat="server" from any one of form tag.

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title></head>
<body>
<form id="form1" >
<div> </div>
</form>
<form id="form2" runat="server">
<div> </div>
</form>
</body>
</html>
If you want only one form tag ,remove unwanted form tag.

Solution 1

"A page can have only one server-side Form tag."

There is more than one form marked with "run at server" on your ASP page. This is obviously not allowed. So the compiler tells you so. It seems you're not listening intently though.

Cheers!
