virtualXHeaderType and slow sorting
« on: March 03, 2015, 09:16:48 pm »
Cheers!

Here is my problem:
I have lot number of columns and few-level header in my table, so I need to set virtualX: true and virtualXHeaderType: false (to display rowspan and colspan correctly). Grid works fine but there's one problem with sorting- it works slow -up to 5 sec. If I set option virtualXHeaderType: true -it work very fast though header displays not properly  :(.
Is it possible to speed up sorting in grid with disabled virtualXHeaderType?

Thanks in advance!

How much is the initial binding and refresh time.

Could you please share a jsfiddle.

Here's my jsFiddle:

Try to test sorting with virtualXHeader true and false.

Thanks!

I found the script for resizable columns is slowing it down, it would be optimized in next version.

Meanwhile you can use resizable: false to make the sorting and refresh time faster.
Code: [Select]
columnTemplate: {resizable: false},
