RadzenDropDownDataGrid Sorting/Filtering with ints

Hello There,

I am having a bit of an issue with sorting and filtering by int values in a dropdowndatagrid. When I use ints, the sorting value sorts from smallest to largest or largest to smallest, which is desired. However, the filter property one might want to use to find a particular value does not work. When I use a string value representing the number, the filter works better - though some values are missing - but the sorting does not work.

Is there a way to have a grid sort numbers by largest to smallest/smallest to largest and also have the filter feature work correctly?

Thanks in advance for any help you can provide me on this issue.
