Nested Gallery avoid auto refresh when collection is updated

[Mugesh]

Hi all, 
We are facing an issue in Nested galleries. We are grouping the main gallery and showing the data dynamically. In addition with that, we are using tabs to show and hide the corresponding data depend upon the tab label fields in the gallery. Whenever we used to validating some rules in the collection, automatically the grid is refreshing and loading like how it will load at the start. This leads to the user manually scroll to the bottom and need to cross check the validated rule. Is any way to overcome this issues. 

Any help would be appreciated.

Regards,
Mugesh.
