A new property of type EmbeddableElementDisplayStyle called DisplayStyle was added to the IDropDownResizeHandleOwner interface. This additional property is used for determining the proper style to apply to the DropDownResizeHandleUIElement. The new property had to be implemented on anything that implements the IDropDownResizeHandleOwner interface, including the UltraPopupControlContainer, the ValueList, the EditorButonBase, and the UltraDropDownBase.
The following table summarizes the breaking changes in Excel library Format support
Previously, when the workbook was created, it used a custom palette mode by default, which meant any colors set on cell formats and fonts were automatically added to the palette.
Now, the workbook palette is not auto-populated. When a custom color is used, and the file is opened in Excel 2003 or earlier, users may not see the used color. They will see the closest color that was present in the color palette at the time of the file creation.
This can be fixed by manually adding in the used colors in the workbook’s palette at any time before saving the workbook. This is not an issue with Microsoft Excel 2007 or later versions.
The following color properties have been marked obsolete. Setting the old property will set the new property to an equivalent value. Getting the old property will get the actual color which will be seen by the user.
The following properties on
IWorksheetCellFormat have been marked obsolete and their functionality has been replaced by a new property.
Setting the old properties to non-default values will set the
Fill property to a CellFillPattern instance corresponding to the values that were set. Getting the properties gets the closest match colors it can from the current
Fill property value. If it is a
CellFillPattern instance, they will be accurate values, but if the new gradient fills are being used, the old properties will reflect a solid fill with a background color of the first gradient stop.
