Put this in your Columns section of the GridView.   Then when you do a postback you would access the selected field with Request.Form["Employee"]
<Columns>
 
<asp:BoundField DataField="FirstName" HeaderText="First Name" />
 
<asp:BoundField DataField="LastName" HeaderText="Last Name" />
 
<asp:TemplateField HeaderText="Select">
 
<ItemTemplate>
 
<input name="Employee" type="radio" value='<%# Eval("EmpID") %>' />
 
</ItemTemplate>
 
</asp:TemplateField>
 
</Columns>

Add a groupname to those radiobuttons where you want only one value selected:

I didn't understand your 2nd question. Can you elaborate on it?

<asp:TemplateField HeaderText="Select">
 
<ItemTemplate>
 
<asp:RadioButton id="RadioButton1" runat="server" GroupName="MyGroup"></asp:RadioButton>
<asp:RadioButton id="RadioButton2" runat="server" GroupName="MyGroup"></asp:RadioButton>
<asp:RadioButton id="RadioButton3" runat="server" GroupName="MyGroup"></asp:RadioButton>
<asp:RadioButton id="RadioButton4" runat="server" GroupName="MyGroup"></asp:RadioButton>
<asp:RadioButton id="RadioButton5" runat="server" GroupName="MyGroup"></asp:RadioButton>
 
</ItemTemplate>
 
</asp:TemplateField>

Correct me if I'm wrong, but I think he only wants one radio button per row and I can't think of any way to do that with an asp.net control.

Using HTML controls you can save the result of the radio button to an hidden field or session variable, so it can be used later in another page.  If that works let me know and I can show you how.

// This code is in the same page (or code behind) as your radio buttons
if (IsPostBack)
{
    //Save to a session variable
    Session["Employee"] = Request.Form["Employee"];
}
 
 
//This code is added to any page that needs to access the session variable
 
//Change the text label to use our radio button session variable
Label1.Text = Session["Employee"];
