My user request me to turn off the paging function of the grid, but it turns out the time for the grid to initialize is quite unacceptable(over a minutes). I have read a page about this problem and it suggested to turn off all client side event of the grid, but it is not possible for me as at least the sorting function and row double click event should be kept. So do you have any other method to better the performance? (My target is to show a few hundred record in the grid with no paging)

And I am curious about something. After I use the paging function, and then I change the page side by the "footer bar" of the grid, and it turns out the performance is okay. So why? Thank you.

Hi Jeff,

Indeed when paging is disabled and you are displaying large number of records it is expected that the page loads slower because the rendered html is significantly more.
Therefore I suggest that you check if enabling the grid Scrolling functionality would work for you:

Further information about optimizing grid performance is available here.

All the best,
