javascript problem

[Michele]

Hello everyone, I have a problem with the javarscript in the grid :

if I put the grid inside an <ASP:Panel> to bring up a screen of data loading:

<telerik:RadAjaxManager ID="RadAjaxManager2" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
        <ClientEvents OnRequestStart="RequestStart" OnResponseEnd="RequestEnd"></ClientEvents>
        <AjaxSettings>
                  <telerik:AjaxSetting AjaxControlID="Panel1">
                         <UpdatedControls>
                              <telerik:AjaxUpdatedControl ControlID="Panel1" LoadingPanelID="RadAjaxLoadingPanel1" />
                        </UpdatedControls>
                 </telerik:AjaxSetting>
      </AjaxSettings>
</telerik:RadAjaxManager>
<asp:Panel ID="Panel1" runat="server" >
        <telerik:RadGrid ID="GriEleRec" runat="server"
            AllowAutomaticUpdates="True" AllowPaging="True"
            AutoGenerateEditColumn="True" DataSourceID="MySQLDataSource"
            GridLines="None" Skin="Web20" PageSize="12"
            AllowAutomaticDeletes="True" AutoGenerateColumns="False"
            style="margin-right: 23px"
            Width="100%"
            OnInsertCommand="InsRep"
            OnDeleteCommand="DelRep"
            OnUpdateCommand="UpdRep"
            AutoGenerateDeleteColumn="True"
            AllowSorting="True">

             .......
             ......

     </telerik:RadGrid>


<script language="javascript" type="text/javascript">
         var currentLoadingPanel = null;

         function RequestStart(sender, eventArgs) {
             check = InStr(eventArgs.EventTarget, "btnEli");
             //alert(check);
             if (check > 0) {
                 eventArgs.EnableAjax = false;
             }
             else {
                 eventArgs.EnableAjax = true;
                 centerElementOnScreen($get("<%= RadAjaxLoadingPanel1.ClientID %>"));
                 HideFrame();
             }

         }

         function RequestEnd(sender, eventArgs) {
             ShowFrame();
         }

         function centerElementOnScreen(element) {
             var scrollTop = document.body.scrollTop;
             var scrollLeft = document.body.scrollLeft;
             var viewPortHeight = document.body.clientHeight;
             var viewPortWidth = document.body.clientWidth;
             if (document.compatMode == "CSS1Compat") {
                 viewPortHeight = document.documentElement.clientHeight;
                 viewPortWidth = document.documentElement.clientWidth;
                 scrollTop = document.documentElement.scrollTop;
                 scrollLeft = document.documentElement.scrollLeft;
             }
             var topOffset = Math.ceil(viewPortHeight / 2 - element.offsetHeight / 2);
             var leftOffset = Math.ceil(viewPortWidth / 2 - element.offsetWidth / 2);
             var top = scrollTop + topOffset - 40;
             var left = scrollLeft + leftOffset - 70;
             element.style.position = "absolute";
             element.style.top = top + "px";
             element.style.left = left + "px";
         }
     </script></telerik:RadCodeBlock>

in which case the grid to do an javascript windows.open or an export to excel gives me a runtime error and I reload the same page

I do something wrong?

Hi Michele,

Remove RadAjaxManager or disable AJAX on the page to get the exception page with the stack trace. It will give you more info on what caused the exception.

If Ajax id disabled or if I'll delete RadAjaxManager the windows.open javascript work fine, but the loading panel don't work.

If Ajax is active like my precedent post i have this error:

Hello Michele,

Are you using Response.Write() in your code? Or are you using both RadAjaxManager and RadAjaxPanel to AJAX-ify one and the same content? Note that the latter scenario is not supported, as discussed in the following help topic.
