The unexpected border array:
14 0 obj
<< /A 16 0 R /Border [ 10 10 10 60 ] /Rect [ 411 36 565 48 ] /Subtype /Link /Type /Annot >>
endobj"In PDF 1.0, the array consists of three numbers defining the horizontal corner radius, vertical corner radius, and border width, all in default user space units. If the corner radii are 0, the border has square (not rounded) corners; if the border width is 0, no border is drawn. (See implementation note 81 in Appendix H.)
In PDF 1.1, the array may have a fourth element, an optional dash arraydefining a pattern of dashes and gaps to be used in drawing the border."
Getting an exception message when trying to view a document as a PDF using the PdfFormatProvider which started happening only after upgrading Telerik to the latest version, 7.1.0 in Telerik UI for Blazor.
Exception Message:
width should be greater or equal than 0. (Parameter 'width')

PdfStreamWriter: "InvalidOperationException: 'isContentReleased'" is thrown when creating a multi-page document with an umlaut on the last page.
Workaround - Explicitly set the block font:block.TextProperties.Font = FontsRepository.Courier;
This is the code for import/export which result is illustrated below:
string inputFilePath = "test1.doc";
Telerik.Windows.Documents.Flow.Model.RadFlowDocument document;
Telerik.Windows.Documents.Flow.FormatProviders.Doc.DocFormatProvider doc_provider = new Telerik.Windows.Documents.Flow.FormatProviders.Doc.DocFormatProvider();
using (Stream input = File.OpenRead(inputFilePath))
{
document = doc_provider.Import(input, TimeSpan.FromSeconds(10));
}
Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider docx_provider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
string outputFilePath = "Exported.docx";
using (Stream output = File.OpenWrite(outputFilePath))
{
docx_provider.Export(document, output, TimeSpan.FromSeconds(10));
}
Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
This results in a missing paragraph. For example, having a table with three cells and Page field in the footer of a document and exporting it to PDF, will not export the last paragraph.
As a workaround add new run after the last field character in the cell's table before exporting the document to PDF.
BlockCollection footerContent = this.document.Sections.First().Footers.Default.Blocks;
Table footerTable = footerContent.First() as Table;
var cells = footerTable.Rows.Last().Cells.Where(x => x.EnumerateChildrenOfType<FieldCharacter>().Any());
foreach (var cell in cells)
{
cell.Blocks.AddParagraph().Inlines.AddRun();
}
In WordsProcessing on import only the lower case CSS attributes are correctly imported. Upper case and mixed case are ignored and the default values are used.
The calculations are wrong, leading to single lines on a page. As a result, the content of the PDF document is laid out on a bigger number of pages.
Workaround: Change the line spacing and its type before exporting to PDF:
foreach (var paragraph in this.document.EnumerateChildrenOfType<Paragraph>())
{
HeightType? heightType = paragraph.Properties.LineSpacingType.GetActualValue();
if (heightType == HeightType.Exact || heightType == HeightType.AtLeast)
{
paragraph.Properties.LineSpacingType.LocalValue = Telerik.Windows.Documents.Flow.Model.Styles.HeightType.Auto;
paragraph.Properties.LineSpacing.LocalValue = 2;
}
}
The exception is thrown because we try to export a tblGrid element, but currently we do not support this: https://feedback.telerik.com/Project/184/Feedback/Details/190082-wordsprocessing-export-tblgrid-table-grid-property-for-table-elements
Importing a document containing a bookmark located in a structured document tag (sdt) will lead to ArgumentNullException.
Import of Tables with border style needs improvements. Currently, it takes multiple seconds to import table with 100x6 cells no matter if the border style is defined globally or locally. This may be seen when importing the attached files "table with borders.html" and "table single border style.html". Importing the same table without borders is achieved in less than a second which may be seen with the attached "table without borders.html".
