I've got a grid set up for Excel export that can potentially be large (~500K rows max). While the performance isn't terribly problematic for the large grids (though any performance tweaks would be welcome!), is there some way I can put a "processing" spinner up so the browser doesn't appear to freeze, or is the browser freeze inevitable given that the processing is primarily in JavaScript?

Hello Harper,

As you know JavaScript is asynchronous and currently such implementation can not be achieved, however we have planned for adding a callback function on excel export event, so you will be notified when the excel file is ready so you can remove the spinner. This addition will be available with the Q1 release.

Hello Ming Fei,

The Kendo Loader can be implemented to show while the Grid is preparing the data for the Excel export. For more information and a runnable demo please refer to the following forum post:

Let me know if you have any questions.
