Hi GridLock,
Thank you for using Syncfusion controls.
In SfDataGrid, columns are generated based on corresponding property type. For example, if you have integer property, SfDataGrid generated the GridNumericColumn type and it has the NumericFilter. We have prepared the sample based on your reported case. Please refer the below sample,
Please check the above sample and revert us if you still facing the same issue? If yes, please modify the sample based on your scenario. It will be helpful for us to check on it and provide you the solution at the earliest.
