When there is long text that is out of the used cell range area, this text should be included in page splitting calculations.

Also, when a cell has text that overflows its width, the text is again clipped by the cell boundaries and is not visible in the exported PDF. In a similar case Excel exports the surrounding cells to ensure that the content is visible.

Workaround: Extend the used cell range to include all the cells which the text content spans.

HTML heading elements (<h1>-<h6>) are imported with the default heading styles (Heading 1 - Heading 6) for RadFlowDocument, which is unexpected, as the browsers and MS Word import them with different styling. 

For example, <h1> is imported as Heading 1 with font the following properties:

Font: Cambria
Font color: Accent 1
Spacing before: 14 pt
Spacing after: 14 pt

While MS Word imports it as:

Font: Times New Roman
Font color: not set (black)
Character spacing: Kern at 18 pt
Spacing before: Auto
Spacing after: Auto

"bolder" font weight is imported as regular font weight in the RadFlowDocument model. Instead, it should be imported as bold.

The data validation rule should have values for formula1 and formula2 elements, which define the start and end values for a range to validate between. When such values are missing, a NullReferenceException is thrown on import and the document cannot be imported.


System.NullReferenceException: Object reference not set to an instance of an object.

Exporting document with a missing image is caused by handled Exception on import for DecodeParms containing null or stream object. Currently, PdfProcessing supports only decode parameters containing simple types. The case when some dictionary value is null or stream object should be implemented.

Another case is when the whole dictionary/stream is null. In this case, an ArgumentNullException is thrown.

By specification, the InteractiveForm fields can have the same name if they are descendants of a common ancestor. Such fields are different representations of the same underlying field; they should differ only in properties that specify their visual appearance. When such a document is imported an ArgumentException: 'An item with the same key has already been added.' is thrown.

When the worksheet contains many formulas which use large ranges (e.g. covering 50000 cells) as arguments and these formulas have to be calculated, this causes OutOfMemoryException.

When a list is just before the table, all of its list items are inserted in the first cell of the table while exporting to HTML.

Workaround: Add a paragraph between the list and the table
foreach (var section in this.document.Sections)
    bool shouldInsert = false;
    foreach (var block in section.Blocks.ToList())
        var paragraph = block as Paragraph;
        if (paragraph != null && paragraph.ListId > -1)
            shouldInsert = true;
        else if (shouldInsert)
            var paragraphToInsert = new Paragraph(this.document);
            paragraphToInsert.Spacing.LineSpacing = 1;
            paragraphToInsert.Spacing.LineSpacingType = HeightType.Exact;
            paragraphToInsert.Spacing.SpacingAfter = 0;
            block.BlockContainer.Blocks.Insert(section.Blocks.IndexOf(block), paragraphToInsert);
            shouldInsert = false;

By specification, the document AcroForm contains fields with no parents. However, some documents may have child fields in the AcroForm. This leads to ArgumentException when importing the child and parent fields - 'An item with the same key has already been added.' since the child field is added twice.

The current implementation uses System.Windows.Media.Imaging.BitmapImage class in order to take the image pixels for the PDF export. However, BitmapImage class throws NotSupportedException when being initialized with a WMF or EMF image.

WORKAROUND: WMF and EMF images may be converted to PNG images before the PDF export. The following code snippet shows how to convert all inline WMF image to PNG images by using System.Drawing.Image class:

private static void ConvertInlineWmfImagesToPng(RadFlowDocument document)
    foreach (ImageInline image in document.EnumerateChildrenOfType<ImageInline>())
        if (image.Image.ImageSource.Extension.Equals("wmf", StringComparison.InvariantCultureIgnoreCase))
            using (MemoryStream wmfImageStream = new MemoryStream(image.Image.ImageSource.Data))
                using (MemoryStream pngImageStream = new MemoryStream())
                    var imageDrawing = System.Drawing.Image.FromStream(wmfImageStream);
                    imageDrawing.Save(pngImageStream, ImageFormat.Png);
                    byte[] pngBytes = pngImageStream.ToArray();
                    image.Image.ImageSource = new ImageSource(pngBytes, "png");

Table and table cell borders are not evaluated according to inheritance and conflict resolution rules. A conflict will occur when different borders from the table and table cell are overlapping. 

The GetActualValue method of the TableBorders and TableCellBorders could potentially return an incorrect value in some of the following scenarios:

Scenario 1:
A table has cell spacing set to 0. Meaning that the table and table cell borders will overlap.
The table borders have defined all of its borders with border style "Single".
The table cell borders have all of its borders defined with border style "None".

Expected result: the resulting borders should have the border style set to "None" for the location where the table and the cell borders are overlapping.

Scenario 2:
A table has explicitly defined that its right border is with border style "None".
The table has a table style applied with defined border style of type "Single" for all table borders.

Expected result: All of the table borders except the right border should have border style of "Single".

The problem is mostly visible when exporting to PDF and RTF format.
