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.

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);

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;

Xlsx documents with a global filter defined cannot be imported. Message box "The name that you entered is not valid." is shown and internally SpreadsheetNameException is thrown. MS Excel can import such document and even preserve the filter, but do not respect it and doesn't have UI to clear it.

Workaround 1 (includes processing the document with MS Excel):
- Open the document in MS Excel
- Choose Formulas -> Defined names -> Named Manager
- Choose Filter -> Names with errors
- Find all Filter defined names and delete them
- Save the document

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:
