Export RadGrid content to Excel with Ajax enabled --> Re-Enable Ajax afterwards?

[Dennis]

I followed your great documentation on Export RadGrid content to Excel/Word/CSV/PDF with Ajax enabled . It works flawlessly - the export itself.

My javascript code is very close to the example code provided:

function requestStart(sender, args) {
    if (args.get_eventTarget().indexOf("lnkExportExcel") >= 0)
        args.set_enableAjax(false);
}

But after exporting the AJAX remains disabled. How do I re-enable AJAX after the RadGrid has been exported? Do i need to refresh the whole page or is there something like "radGrid.Re-EnableAJAX()" via Javascript?

Maybe you could update your documentation on re-enabling Ajax as well.

Hello Dennis,

In your page ajax is already enabled.
If fire click event of lnkExportExcel then and then only it disable ajax else it already enabled.

Note : Please check this Export in Radgrid demo.
In this demo when you export at that time it disable ajax.
but after exporting when we change the paggging,  at that time ajax is already enabled (means not need to re enable).


Thanks,

Hello Dennis,

When the Ajax is enabled on the server it should be enabled by default after every postback even if you disable it on the client. This happens because the enabled setting is not persisted when changed client side and the next time the page loads it will be enabled again. Additionally you can try to place the LinkButton outside the Panel which is ajaxified. Also take a look at the following help documentation.
Export from Ajaxified Grid.

Thanks for the information and you are correct. When I load my UserControl in a regular web application AJAX works after clicking the Excel Button, however when using the userControl in SharePoint (on an Application page) Ajax doesn't work anymore, though it looks like a Postback.

Any experiences on how SharePoint might interfere with the export?
