Updating of the asp.net dropdown control using javascript -

in asp.net default.aspx, have dropdown list command , next javascript code

<asp:dropdownlist id="ddlgenres" runat="server" appenddatabounditems="true" autopostback="true" datasourceid="entitydatasource2" datatextfield="cityid" datavaluefield="cityid" onselectedindexchanged="ddlgenres_selectedindexchanged" clientidmode="static" > <script type="text/javascript"> var ddlclientid = '<%=ddlgenres.clientid%>'; //document.getelementbyid(ddlgenres) function setddlval(nindx) { //$("#ddlgenres") var ddllistselect = document.getelementbyid(ddlclientid); ddllist.selectedindex = nindx; } </script>

====================================================================

in external javascript file, calling function setddlval. debugged code , ddllist selectedindex changed within script.

=====================================================================

the issue facing is, when selectedindex value changed in javascript, ddlgenres_selectedindexchanged code not beingness triggered. please allow me know if missing anything. nate

in javascript property of <select> input selectedindex not selectedindex.

change function this:

function setddlval(nindx) { var ddllistselect = document.getelementbyid('<%=ddlgenres.clientid%>'); ddllistselect.selectedindex = nindx; }
