Virtual Mode server requests on key down event

[Igor ShakolaParticipant]

Hi,
We’re looking to use jqxGrid for a project to potentially display hundreds of thousands of rows. Virtual Mode works fine.
However, a very common user scenario: user presses down arrow and scrolls the table searching for particular row, assume each second. The last row becomes always selected and each time the button is pressed server side call occures. Example:
– initially visible range is 0-12. server side call range 0-37
– I select last row and press down arrow. new visible range: 1-13. sever side call range 1-28
– I press down arrow again. new visible range: 2-14. sever side call range 2-29

I noticed the same behaviour in virtual scrolling example.
Is there a way to prevent server side calls until its really required? ( In example: starting from 38 element… )

BR,
Igor
