RadGrid filtering and grouping wiht custom paging

[Himanshu]

Hi....All
I have implemented custom paging for radgrid.
It was working fine till I enabled grid for filtering and grouping.

Again....custom paging is working effectively when filtering or grouping is not used. I want to use custom paging effectively with filtering and grouping.

By Effective custom paging, I mean  fetching only those rows from database which are to be shown in grid ( according to page selected, filtering criteria applied or grouping applied)

wating for reply......

Hi Himanshu,

When the grid is in custom paging mode all operations like filtering, sorting & grouping will be applied for the entire data source by default however you can control this at your business objects collection level if you return only needed data.

Hi Vlad,

Can you please share an example code on how to do this?

The current example is not useful.

Hi Kasim,

 

Custom paging can be applied only for "Paging". When adding filtering/grouping/sorting operations the custom paging should be disabled at that moment, as demonstrated in the sample:
https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/paging/custom-paging/defaultcs.aspx

More specifically, this line of code:

 RadGrid1.AllowCustomPaging = !ShouldApplySortFilterOrGroup();
