Grid export problem with Ajax

[wdudek]

I found the link on http://www.telerik.com/community/code-library/aspnet-ajax/general/export-radgrid-content-to-excel-word-csv-pdf-with-ajax-enabled.aspx regarding exporting from an ajaxified grid. It sounded easy enough but I have yet to get this to work. When I click on my export button I can step through the debugger and see the export to excel method of the master table being called but nothing happens after that.  I basically have a link button, rad grid and an ajax manager. For brevity here is the code for the ajax mgr and the java script. 

function mngRequestStarted(ajaxManager, eventArgs) {
        if (eventArgs.EventTarget == "linkExportOrders" ) {
            eventArgs.EnableAjax = false;
        }
    }

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" ClientEvents-OnRequestStart="mngRequestStarted" >
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="linkSearch">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="rightClickMenu" />
                <telerik:AjaxUpdatedControl ControlID="txtPoLookup" />
                <telerik:AjaxUpdatedControl ControlID="linkSearch"
                    LoadingPanelID="ajaxOrdersLoadingPanel" />
                <telerik:AjaxUpdatedControl ControlID="lnkExcluded" />
                <telerik:AjaxUpdatedControl ControlID="panelFunctions" />
                <telerik:AjaxUpdatedControl ControlID="panelControls" />
                <telerik:AjaxUpdatedControl ControlID="linkExportOrders" />
                <telerik:AjaxUpdatedControl ControlID="radPurchaseOrder" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="btnClearSearch">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="pnlSearch" />
                <telerik:AjaxUpdatedControl ControlID="panelControls" />
                <telerik:AjaxUpdatedControl ControlID="linkExportOrders" />
                <telerik:AjaxUpdatedControl ControlID="radPurchaseOrder" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="linkExportOrders">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="linkExportOrders" />
                <telerik:AjaxUpdatedControl ControlID="radPurchaseOrder" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

Anyone else had this problem and not been able to resolve it from the sample app? Or see that I'm doing something totally wrong?
Thanks
Bill

Hello Wdudek,

It seems to me that the client ID of the control won't match in this expression:

eventArgs.EventTarget == "linkExportOrders"
...

I would recommend that you try to replace this code as shown below:

if (args.get_eventTarget().indexOf("linkExportOrders") >= 0)
    args.set_enableAjax(false);

I hope this helps.

Daniel, 

    That did it, I used the following which was slightly differnt although from my understanding would actually call the method you listed? Is there any benefit to doing it one way or the other? i.e. calling a proprty versus the underlying method??

function mngRequestStarted(ajaxManager, eventArgs) {
    if (eventArgs.EventTarget.indexOf( "linkExportOrders") > -1 ) {
        eventArgs.EnableAjax = false;
    }
}

Hello Wdudek,

The only real difference is that the EventTarget / EnableAjax are deprecated long time ago and will be removed at some point. This is why I recommend that you use their get/set counterparts.

Kind regards,
