asp.net - How to write the radcombobox selectedindexchange event in javascript? -

-

i don't know how write javascript function in radcombobox selectedindexchange.

asp.net

<tr> <td> <asp:label runat="server" id="label73" cssclass="labels" text="call response"></asp:label> </td> <td> <telerik:radcombobox runat="server" skin="metro" id="cbocallresponse" autopostback="true" emptymessage="select call response" zindex="100001"> <items>                                                             <telerik:radcomboboxitem value="attended" text="attended" />                                                             <telerik:radcomboboxitem value="noanswer" text="noanswer" />                                                             <telerik:radcomboboxitem value="callbacklater" text="callbacklater" />                                                             <telerik:radcomboboxitem value="number not exists" text="number not exists" />                                                             <telerik:radcomboboxitem value="wrong number" text="wrong number" /> </items> </telerik:radcombobox>  <span class="warning">*</span>                                                     <asp:requiredfieldvalidator id="requiredfieldvalidator8" runat="server" cssclass="warning" text="select call response" controltovalidate="cbocallresponse" validationgroup="callvalidate"></asp:requiredfieldvalidator> </td> </tr>

vb.net

private sub cbocallresponse_selectedindexchanged(byval sender object, byval e telerik.web.ui.radcomboboxselectedindexchangedeventargs) handles cbocallresponse.selectedindexchanged         if cbocallresponse.selectedvalue = "callbacklater"             pnlschedule.visible = true             popwindow(radcalllog)         else             popwindow(radcalllog)         end if     end sub

i want write down javascript function selectedindexchange because every selectedindex postback.

i'm not sure popupwindow here solution is

  <telerik:radcombobox runat="server" onclientselectedindexchanged="cl_indexchange" skin="metro" id="cbocallresponse" autopostback="true"                                                         emptymessage="select call response" zindex="100001">                                                         <items>                                                             <telerik:radcomboboxitem value="attended" text="attended" />                                                             <telerik:radcomboboxitem value="noanswer" text="noanswer" />                                                             <telerik:radcomboboxitem value="callbacklater" text="callbacklater" />                                                             <telerik:radcomboboxitem value="number not exists" text="number not exists" />                                                             <telerik:radcomboboxitem value="wrong number" text="wrong number" />                                                         </items>                                                     </telerik:radcombobox>

into <script> tag

  <script language="javascript" type="text/javascript">         function cl_indexchange(sender, eventargs) {             var pnl = document.getelementbyid("pnlschedule");             var item = eventargs.get_item();             if ( item.get_text() == "callbacklater")                   pnl.style.display="none";                 else                  //if make visible                   //pnl.style.display="block";                   ....          }     </script>

hope helps
