Following are the breaking changes for ExcelOpenFlags enumeration.
| ComboDataOnly | ComboDataOnly is a deprecated flag of ExcelOpenFlags enumeration. Use DataValidationAsCombo instead. |
| DocumentCachingOnly | DocumentCachingOnly is an obsolete flag of ExcelOpenFlags enumeration. |
| PreferDateTime |
While importing in Spread for WinForms 10, a cell with a number value and date time format string was corvered to .NET DateTime object. In Spread for WinForms 11, this conversion logic is not support. To revert to the old behavior, use PreferDateTime flag of ExcelOpenFlags enumeration. |
| Does not convert double to decimal | Spread for WinForms 11 no longer converts double to decimal value. Since Excel stores numbers as double, it improves the performance when importing from Excel. |
