I have a grid with around 20,000 items in it and when I click export
to excel with .AllPages set to true, I get an unresponsive script error.
I've traced the SQL query and that is quick, taking only 1 second to
complete but I can see the ajax call taking far too long and ultimately
failing after around 15-20 seconds. What are my options for this? Is
there an alternative approach involving server-side?
I would guess this is because there are a lot of items in the grid and your example on your demo page only does the current page ?
