Dear Syncfusion,
In the filtering for Syncfusion data grid especially for date type data, it is impractical when we want to select or deselect date based on year/ month? We need grouping interface like microsoft excel to make the user work faster with checkbox listing to select period based on year/ months with only check/ uncheck the year/ month/ date. Excel interface nowdays more humane for user to work faster and efficient,
Here is the example from Microsoft Office Excel (data grouped by years, months and date):

your current feature:

I hope Syncfusion can applied this feature in Data Grid WPF for user friendly interface and make them work faster and efficient rather than tick untick one by one
Thank you anyway :)
