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.
At the moment the print settings set to the WorksheetPageSetup class are not passed to the Print dialog which leads to bad user experience. If you set the print settings of the RadSpreadsheet like so: WorksheetPageSetup pageSetup = this.radSpreadsheet.Workbook.ActiveWorksheet.WorksheetPageSetup; pageSetup.PageOrientation = PageOrientation.Landscape; and then select Print, the Spreadsheet print menu will show the print preview as landscape. However, when after that you click on Print for the default print dialog to appear and then click Preferences, you will notice that the preference is set to Portrait. The print job will be Landscape, but the incorrect information in the default dialog creates confusion. This is an example of how to set the preference of the default dialog: PrintDialog printDialog = new PrintDialog(); var printTicket = printDialog.PrintTicket; printTicket.PageOrientation = System.Printing.PageOrientation.Landscape;
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.
Check how the performance can be improved in this scenario. The StyleGallery is taking much time to load, the GetUsedCellRange method is called multiple times.
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.
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.
XLSB is binary format that should theoretically allow fast reading and writing to the file.
Steps to reproduce: - Open RadSpreadsheet -Put 1 in B2 and B6 -Put 0 in B3, B4, B5 -Add filtering on columns A and B -Filter on column B to have only rows with 1. The rows 3 to 5 will be hidden. -Paste "1234" as cell selection in the Range A2:A6 Note: It is important to enter 1234 in another cell, make a cell selection and then paste it -Remove the filter Expected: "1234" in pasted in cells A2 and A6 only. Actual: "1234" in pasted in cells A2, A3, A4, A5, A6.
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 the moment when any of the properties are changed, e.g. the frozen panes, the UI is not notified and you have to export and import the file in order for the UI to pick them up. Workaround: There are several workarounds: 1. Change the active worksheet and return to the old one 2. Export and import the document 3. Change the workbook of the RadSpreadsheet to a new one, and return the old one after that
