Borders can overhang 1 px from the corresponding cells. The issue is reproducible only on some zoom levels, and is most probably related to WPF layout rounding. The issue is mostly visible when borders are missing. On different zoom levels, different borders are hanging.
It would be useful to allow the printer to be chosen directly from the Print Preview control (in the File menu in the ribbon UI). Currently the user should first press Print, and then can choose the printer in the Printer dialog, which is inconvenient.
ArgumentException is thrown ("Error: Argument1" message box in case of importing through RadSpreadsheet) when importing document containing cell with applied custom data validation rule restricting the value of the cell to empty values only - '""' (two double quotes).
Add API for notification when the value in a cell determined by formula is changed. This way the user can find whether by changing a cell value the result of a formula that refers to that cell value is changed. For example: A1: 100 A2: 5 A3: =A1+A2 When A2 is changed, the notification should be rise for A3 (as its value is also changed).
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.
Implement Show Formulas command, which display the formulas in the cells instead of the result value. In MS Excel, this is available in Formulas -> Formula Auditing -> Evaluate Formula. The keyboard shortcut is "Ctrl + ~".
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.
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
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.
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.
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.
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 creating Tables and applying tables styles (predefined ones or custom).
Implement functionality to rotate the text in a cell.
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.
Add support for conditional formatting of cells - allow applying of rules used during visualization of cells to automatically apply formatting depending on their values.
