Greetings,
I'm using a Kendo Grid with server paging and filtering, as we are handling big data, our data source only contains a limited number of records based on the page number and the number of records to be displayed.
with the grid, I'm using row filtering.
as the grid data-source doesn't contain all the possible values, the filter auto-complete doesn't show all the correct possible option, so I changed the columns.filterable.cell.dataSource to get those needed values through an ajax call that returns distinct values.
That worked fine but as I'm handling big data, the filter became slow and even freeze (I'm testing on a table that has about 25000 record and it's not the biggest one).
What I want to do is using the columns.filterable.cell.minLength to limit the number of records returned in the auto-complete but I wasn't successful as the filter data-source gets called when I load the grid and not when I start setting the filter value, I tried used a template function but without any success.
Is there a better approach to make the cell datasource read the value when the user start typing the filter, and with consideration to the value being input?
Thanks,
