Add support for conditional formatting of cells - allow applying of rules used during visualization of cells to automatically apply formatting depending on their values.
The sheet selector should hide sheets when their visibility is set to hidden or very hidden. The context menu of the sheet selector should contain Hide and Unhide options that allow to hide a sheet or unhide one of the hidden sheets.
Implement functionality to rotate the text in a cell.
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.
Add support for creating Tables and applying tables styles (predefined ones or custom).
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.
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.
- 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.
XLSB is binary format that should theoretically allow fast reading and writing to the file.
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.
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
Currently, the customers can bind data only to the Workbook property of RadSpreadsheet. Allow them binding cell range to a data source.
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.
Implement mechanism for disabling, enabling or changing of the commands of the CellEditor classes, like Copy and Paste.
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.
