Web Forms :: Multiple Tag Appearing - User Control Alternative

I have user control page (.acsx file), which has following

<form action=abcd.aspx id="safsdf">
<input name="q" type="text" value="Search this site" size="13" onfocus="this.value='';"/> //this is input box
<input type="submit" name="sa" value="Submit" />
//this is input button </form>

When user click on submit button, then it postback to same page. I have another page , which reference to this user control and that is why multiple <form> tag appears on one single page and it cause my webpage to layout incorrectly. I would like to remove <form> tag from my above user control and replace with some other alternative, which does postback to same page without using <form> tag on user control (I have to remove <form> tag from user control because I must keep my <form> tag on other page).
