Column FilterChoiceCount Limit is not working

[Blazor]

Hi,
I am testing this sample;
https://blazor.syncfusion.com/documentation/datagrid/excel-like-filter#customize-the-filter-choice-count

I have changed;

args.FilterChoiceCount = 2;
And expecting max 2 result in filter dialog. But result is more then this. Am i missing something?

Thanks for your patience,

We are glad to announce that, we have included the fix for the issue  “The grid FilterChoiceCount property fails to restrict the number of displayed distinct values in excel/checkbox filter dialog.” in our 28.2.11 release.  So please upgrade to our latest version of Syncfusion NuGet package to resolve the reported issue. Please find the NuGet package for the latest fixes and features below.

NuGet : https://www.nuget.org/packages/Syncfusion.Blazor.Grid

Root cause : Previously, we had OnActionBegin and OnActionComplete events for handling the beginning and completion of grid actions. Later, we separated each action based on individual features like filtering, grouping, and sorting. When a filtering action occurs, it processes based on the corresponding arguments. In this issue, the FilterChoiceCount and customFilterData were being updated only when the OnActionBegin event was triggered. This caused a problem where, if the event was not triggered as expected, these values were not correctly assigned, leading to incorrect filtering behavior in the Excel/checkbox filter dialog.

Action Taken: The solution ensures that whenever OnActionBegin or any filtering-related event is triggered, both FilterChoiceCount and customFilterData are properly updated. This is achieved by checking if FilterChoiceCount has a valid value from the event arguments; if not, it falls back to the provided filterChoiceCount parameter.
