    Following are the breaking changes for DefaultSheetDataModel.

    DefaultSheetDataModel.ClearData(int row, int column, int rowCount, int columnCount)

    In Spread for WinForms 10, calling this method used to clear data only.

    In Spread for WinForms 11, calling this method will now also clear Formula of cells in the range along with the data.


    Reference Spread WinForms 11 will not keep reference after a user assigns DefaultSheetDataModel to the model of SheetView. This means that when the DefaultSheetDataModel is assigned to the new DataModel of SheetView, users can just perform the copy operation. The reference to the assigned model won't be kept anymore.

    Back to Breaking Changes for Version 11.40.20177.0.
