Currently, the implementation of the PdfFormatProvider supports the import of Link and Widget annotations. However, other annotation types, such as Text and Pop-up annotations, are imported with limited support - only some of their visual appearance properties are imported. This leads to unpredictable results when exporting or merging. However, the exception could be avoided and the annotation can be skipped. This will ensure the client application is running without errors.

Removing a row causes the last row of the sheet to copy its styling from the first row. This happens because the compressed lists translate the values of the cells up and do not take into account that its the end of the sheet.

I open an xlsx file thant i create with Excel and edit it with RadSpreadProcessing.

But then I can't display it in a RadSpreadsheet control. An error is displayed during execution on localhost.

Here is the error message:

If a workbook was created with Excel, an error prevents it from being opened programmatically in a RadSpreadsheet control. Although it can be displayed there using the open button of the RadSpreadsheet. This error does not occur if you copy the contents of this workbook into the RadSpreadsheet and then save it with the save button on the RadSpreadsheet.

Thank you

When importing an embedded Type 1 Font with custom encoding an InvalidCastException is thrown.
Last Updated: 17 Sep 2020 10:24 by ADMIN

When a TrueType font is defined, the mapping of character codes to glyph indices depends on the built-in cmap table mappings defined in the font and the Encoding property defined in the PDF dictionary.

However, the current implementation maps all characters with cmap tables for Microsoft Symbolic and Macintosh Roman, which causes incorrect mapping results, e.g. space characters are mapped to an Ê glyph.

The issue is also described in the following public item: TryGetCharCode for OpenTypeFont uses wrong cmap and returns wrong charcode.

Workaround: Change the font  of the TextBoxField's widget appearance:
foreach (var widget in field.Widgets)
    widget.TextProperties.Font = FontsRepository.Helvetica;

Workaround: Use the ISBLANK function.
