hi ali If you give your select object an id: [HTML] [/HTML] then you can get the selected value using: function Getval() { document.getElementById(selId).value or var selObj = document.getElementById(selId); val = selObj.options[selObj.selectedIndex].value; //now you have value you can use it to put it into your url onclick of submit button.... using this function.. insertParam(Selectedvalval); } function insertParam ( key  value ) { key = escape ( key ); value = escape ( value ); var kvp = document . location . search . substr ( 1 ). split ( '&' ); var i = kvp . length ; var x ; while ( i --) { x = kvp [ i ]. split ( '=' ); if ( x [ 0 ]== key ) { x [ 1 ] = value ; kvp [ i ] = x . join ( '=' ); break ; } } if ( i 0 ) { kvp [ kvp . length ] = [ key  value ]. join ( '=' );} //this will reload the page it's likely better to store this until finished document . location . search = kvp . join ( '&' ); } now onclick of submit button call the function GetVal(); and you problem should be resolved... all the best.... please mark the answer if my effort is useful

Thanks for your reply I thought of this but for textboxes I did this: Devicename = Request[txtdevicename].ToString(); I thought maybe there is a similar way for select ??

hi friend There are two ways.. either use session of send the selected value with url... for session: Session[selectedvalue]=ddlgrp.SelectedValue.text; and retrieve it as: string value=Session[selectedvalue].ToString(); or you can send the value in parameter as Response.Redirect(~/Anypage.aspx?val=ddlgrp.SelectedValue.text); if it is your answer then please mark it...
