<form runat="server" name="form1">

<SELECT multiple size="7" name="testCategory" > 
			      <option value="volvo">Volvo</option>
                  <option value="saab">Saab</option>
                  <option value="mercedes">Mercedes</option>
                  <option value="audi">Audi</option>
			    			<asp:Button id="testbtn" runat="server" text="test call" />
<SELECT  CLASS="AdHoc_Form_RIGHT" multiple size=17 name=mainlist></SELECT> 			    			

    function testfuntion() {
