Add support for conditional formatting of cells - allow applying of rules used during visualization of cells to automatically apply formatting depending on their values.
Provide the ability to work with images in headers/footers of a worksheet. Note that large images put in headers are visualized as watermarks on printing/exporting to PDF.
Add support for preserving and exporting the macros in a macro-enabled workbook. Macros are pieces of code written in Visual Basic for Applications (VBA) which are used to automate repetitive tasks in excel. The macros are part of the excel file. When a file contains a macro its extension becomes xlsm. Spreadsheet should be able to import and export xlsm files and edit the macros in them.
- Async parse of single xml file to speed-up the import - Allow to import only part of the file - Respect the widths of the columns and row heights and do not measure them first time in the WorksheetLayout or measure them for the current Viewport only - Inserting rows/columns also need improvements in terms of performance.
Grouping is a mechanism to organize data in sections, in order to be able to show and hide the relevant chunks. Each row or column which is part of a group is assigned an outline level, which determines the level of grouping and from there which rows or columns it is grouped with.
If a worksheet spans more than one page, you can print row and column headings or labels (also called print titles) on every page to ensure that the data is properly labeled.
Enable copy-paste of content from and to Excel, preserving all of the applied formatting, styles and images. Currently, RadSpreadsheet supports only CSV for exchanging clipboard data with Excel, and all formatting (including number formats and data validation) is lost.
Add support for creating Tables and applying tables styles (predefined ones or custom).
XLSB is binary format that should theoretically allow fast reading and writing to the file.
Add support for import and export of Excel Template files (XLTS) file format.
At this point, the ribbon and the context menu are not localized out of the box and the users need to change the strings manually.
In MS Excel, there is splitter that can be used to manually resize the formula bar. Also there is an arrow button which expands/collapses the formula bar to the last manually resized size.
Currently, the customers can bind data only to the Workbook property of RadSpreadsheet. Allow them binding cell range to a data source.
This is similar to Visual Studio's IntelliSense, but appears while typing formulas in cells on in the FormulaBar. https://support.office.com/en-us/article/Use-Formula-AutoComplete-6d13daa5-e003-4431-abab-9edef51fae6b
When the user clicks in the gray area of the scrollbars, the view could scroll one page at this direction, similar to what MS Excel do.
Currently, to change the title of the ribbon, the users need to replace RadSpreadsheetRibbon with its XAML code. Expose a property allowing to do this change directly from RadSpreadsheetRibbon.
