ASP. NET does not support multiple runat = server forms on the same page. To solve this problem, you can place each form in a single panel control, in this way, you can simply switch between different panels using single-choice buttons.
The Code is as follows:
2FormExample. aspx

<% @ Page language = "c #" Codebehind = "2FormExample. cs" AutoEventWireup = "false" Inherits = "_ 3leaf_app.C2FormExample" %>
<Html> <Meta name = vs_targetSchema content = "HTML 4.0">
<Meta name = "GENERATOR" Content = "Microsoft Visual Studio 7.0">
<Meta name = "CODE_LANGUAGE" Content = "C #"> <Body>

<Form method = "post" runat = "server" ID = Form1>
<P> Lookup
<Asp: RadioButton id = RadioButton1 runat = "server" Text = "First Name" AutoPostBack = "True" groupname = g1 checked = True> </asp: RadioButton>
<Asp: RadioButton id = RadioButton2 runat = "server" Text = "Last Name" AutoPostBack = "True" groupname = g1> </asp: RadioButton> </p>
<P> </p>
<P>
<Asp: Panel id = Panel1 runat = "server" visible = True>
First Name:
<Asp: TextBox id = TextBox1 runat = "server"> </asp: TextBox>
<Asp: RequiredFieldValidator id = RequiredFieldValidator1 runat = "server" ErrorMessage = "*" ControlToValidate = "TextBox1"> </asp: RequiredFieldValidator>
<Asp: Button id = Button1 runat = "server" Text = "Submit"> </asp: Button>
</Asp: Panel>
<Asp: Panel id = Panel2 runat = "server" visible = False>
Last Name:
<Asp: TextBox id = TextBox2 runat = "server"> </asp: TextBox>
<Asp: RequiredFieldValidator id = RequiredFieldValidator2 runat = "server" ErrorMessage = "*" ControlToValidate = "TextBox2"> </asp: RequiredFieldValidator>
<Asp: Button id = Button2 runat = "server" Text = "Submit"> </asp: Button>
</Asp: Panel>
<P> </p>
<P>
<Asp: label id = Label1 runat = "server"> </asp: label>
</P>
</Form>

</Body>
