how to Add Web UserControl into .aspx page

hi , any one help me to add a web usercontrol intp website (using C#).
I created a Login Web UserControl under <form> tag like this:
<form id="LoginControl" runat="server">
    <asp:label
    <asp:textbox>//for input Username
    <asp:label
    <asp:textbox>//for input Passord
   <asp:Button>//For submit login
</form>
This is my LoginWebUsercontrol.ascx, and i have codebehind for checking Login and event submit
Now, how can i add this into home.aspx
If home.aspx have  <form runat=server></form>, when i add it to Home.aspx MANUALY like (use LoadControl method then i added it). I got error "..Can not have 2 <form> tag " I though it is because there a <form> in WebUserControl and other <form> in Home.aspx...
Now i clear <form> in Home.aspx, but still did not work at all
Thanks for any help

You should not have a <form> tag inside a user control, since when a user control is added to a aspx page the form tag will come with it; which is not what you may want. You should just have the two text boxes inside the control.

To add the control to the aspx page, add the @register directive like this...
<%@Register TagPrefix="mycontrol" TagName="login" src="LoginWebUserControl.ascx"%>

you can then use the control as
<mycontrol:login />
