Title: Touch support and virtual scroll at the same time
Post by: youngvan on December 02, 2015, 08:10:24 pm

Cheers!
I have a large amount of data in tables so I need to use "virtual scroll" modes and I want to add touch device(tablets and smartphones) support for my reports.
Is it possible to use touch mode with enabled virtualX and virtualY modes?

I'm using PQ v3.1
Thanks!

swipe is not supported in virtual mode but pqGrid scrollbars can still be used to scroll viewport in touch devices.

Are you going to add this possibility in future?
I believe it'd be a very useful functionality, considering of mobile devices era.

swipe support doesn't seem worth the effort with lot of rows or columns (virtual mode).

If we think from the perspective of the users, how many times the user would has to roll his finger on the screen (swipe ) to scroll through thousands of records or columns. The user would either leave the page or would get exhausted. Scrollbars are indispensable with large recordsets and swipe support can be provided when the scrollable recordset is small ( non virtual mode).

We are not talking about thousands

iPhone 6 hang out on table with 400 rows and 20 columns

it's reliable table for mobile device with 400 rows only
