If you implement getters like **columns[]**.[calculateCellValue](/api-reference/_hidden/GridBaseColumn/calculateCellValue.md '/Documentation/ApiReference/UI_Components/dxDataGrid/Configuration/columns/#calculateCellValue') in your DataGrid, set **returnDataField** to `false` or utilize the [getCombinedFilter()](/api-reference/10%20UI%20Components/GridBase/3%20Methods/getCombinedFilter().md '{basewidgetpath}/Methods/#getCombinedFilter') method.
