An ArgumentOutOfRangeException is thrown when importing a spreadsheet with the first sheet hidden: VisibleSheetCount should be greater or equal to 1.

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);

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:

<Style  TargetType="spreadsheetControls:RadSpreadsheetFormulaBar" BasedOn="{StaticResource RadSpreadsheetFormulaBarStyle}">
            <Setter Property="Foreground" Value="White"/>

The BitmapImage class throws the exception. We could show some kind of no-image-placeholder instead of throwing exception, or skip the image.

Telerik Reporting creates such files.

Attached is a sample project demonstrating how to customize the Open command descriptor to remove .emf images just after importing the document.
