Added

Fixed

• Data Grid
  • NullReferenceException occurs when DxCheckBox changes the ShowFilterRow property value
  • NullReferenceException occurs if the grid is empty and DxDataGridComboBoxColumn is used with a hidden filter row

• Upload - Changes in the UploadMode enumeration, AcceptedFileTypes property, and upload events (compared to v19.2.4-Preview)
