This works in Excel when the cells are within the same column.

Release LIB 2019.3.1104 (10/07/2019)

The issue is a regression introduced in R3 2019. When the cells in a hidden column are with IsWrapped=true, an ArgumentOutOfRangeException is thrown during the text measuring. The behavior is related to SpreadProcessing as well.

Workaround: Remove the wrapping from the hidden cells:


var usedCellRange = workbook.ActiveWorksheet.GetUsedCellRange(new IPropertyDefinition[] { CellPropertyDefinitions.IsWrappedProperty});

for (int row = usedCellRange.FromIndex.RowIndex; row <= usedCellRange.ToIndex.RowIndex; row++)
    for (int column = usedCellRange.FromIndex.ColumnIndex; column <= usedCellRange.ToIndex.ColumnIndex; column++)
        if (workbook.ActiveWorksheet.Columns[column].GetHidden().Value)
            workbook.ActiveWorksheet.Cells[row, column].SetIsWrapped(false);

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;

Currently, when the user is editing a cell and saves the document without leaving the edit mode first, the current value is not preserved in the saved document.
When pressing the File -> Save button in the ribbon, the Save dialog doesn't appear at all.
Workaround: Manually commit the change before saving. This workaround will also respect data validation:
var layer = ((NormalWorksheetEditorPresenter)radSpreadsheet.ActiveWorksheetEditor.ActivePresenter).UILayers.GetByName(WorksheetPredefinedUILayers.CellInput);
CellInputUILayer cellInputUILayer = (CellInputUILayer)layer;

Customers are reporting an issue when trying to copy content in an application hosted on a remote machine (there are reports using TigerVNC and Citrix).  The exception is thrown from the Clipboard class with a message: OpenClipboard failed (Exception from HRESULT: 0x800401D0 (CLIPBRD_E_CANT_OPEN))

It seems like such a behavior could be reproduced when the clipboard is already opened by another application. Here is a discussion on the matter:
