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 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.
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.
Implement UI for hiding sheet. The sheets can be visible, hidden, or very hidden (could be made visible only from the API). Note: This is already supported on model level (in RadSpreadProcessing).
I think it would be really cool to include a search bar in the filter window, as implemented in Excel (Please find attached a screenshot for demonstration). This is a very useful functionality, as there may be too many options to choose from is the filter is added to subject ID, which could result in thousands IDs.
Currently it's not possible to disable the fill handle feature. Provide API for disabling it.
Workaround: in the attached project.
In the spreadsheet control you cannot link/use in a function cells from one work sheet to cell(s) in another work sheet. Would like to have the same behavior and functionality of Excel, which allows you to use data from one sheet in any other sheet in the work book. Need the ability to create a sum of (or any other function available) cells from another worksheet in my current worksheet, within the same workbook.
