Add support for text orientation (rotation). This is supported in the SpreadProcessing model.

Add support for creating Tables and applying tables styles (predefined ones or custom).

Among the other worksheet protection options, the customers can choose options like "Select locked cells" and "Select unlocked cells", enable or disable formatting options, insertion or deletion of different elements. These settings at the moment are not supported

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.

Currently, the customers can bind data only to the Workbook property of RadSpreadsheet. Allow them binding cell range to a data source.

Returns a Range object that represents the current region. The current region is a range bounded by any combination of blank rows and blank columns. If we want to be consistent with MS Excel we should implement this property. It is useful for many operations of a region such as filtering(selecting one cell and executing the Filter command should apply it to the current region), sorting, selecting all and etc. This document will be useful: https://docs.microsoft.com/en-us/office/vba/api/excel.range.currentregion.

ArgumentException when loading document with a FontDize less than 0.01. 

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. 

Value of a cell is visualized outside of the cell boundaries, or the value is clipped and partially visible, when the cell is updated (from code-behind), while being in an inactive worksheet, and is referenced by another cell from the active sheet.

Workaround: get a value of some cell in the active sheet and set it again to the same cell.

The issue is reproducible after the official release of Q1 2015.

When RadSpreadsheet is placed inside a data template and the Workbook property is bound, the binding fails. 

In the Convert() method of the debug converter, the proper value is set. However, an empty workbook is displayed in the view.

Implement support for ChartSheet 

Please add support for cell content rotation.

 

I know that this is listed in the known unsupported features article, but just to be extra clear about what I am requesting, here's an example from Microsoft Excel

Number format not working when the decimal separator is set to comma.

Selectionchanged is firing two times when changing the active worksheet.

Add information about the selection in the SelectionChanged event arguments. 

- We need to differentiate from mouse event to keyboard event. But since the EventArgs is empty we are not able to differentiate.

Improve the load time when the ribbon UI is used.

 

Currently, the HyperlinkClicked event of RadWorksheetEditor is raised only for external hyperlinks (web and mailto addresses). Raise the event also for links pointing to the a cell in the same document.
