The hanging indent of the paragraph affects the rendering of content with tabs. However, the indent is not respected while generating the PDF, leading to disordered content.
Workaround: Insert a tab stop with the position set to the value for hanging indent:
foreach (var paragraph in this.flowDocument.EnumerateChildrenOfType<Paragraph>())
{
if (paragraph.Properties.HangingIndent.HasLocalValue)
{
Run run = paragraph.EnumerateChildrenOfType<Run>().Where(r => r.Text == "\t").FirstOrDefault();
if (run != null)
{
paragraph.TabStops = paragraph.TabStops.Insert(new Telerik.Windows.Documents.Flow.Model.Styles.TabStop(paragraph.Properties.HangingIndent.LocalValue.Value));
}
}
}
In a WPF project targeting .NET 6, the following code snippet results in an error:
public MainWindow()
{
InitializeComponent();
Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider provider = new Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider();
RadFlowDocument document = provider.Import("<html><body><h1>My First Heading</h1><p>My first paragraph.</p></body></html>");
}System.IO.FileNotFoundException: 'Could not load file or assembly 'System.Text.Encoding.CodePages, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.'
Workaround: edit the .csproj file and include the required package reference:
<ItemGroup>
<PackageReference Include="Telerik.Windows.Documents.Flow" Version="2024.2.426" />
<PackageReference Include="System.Text.Encoding.CodePages" Version="7.0.0" />
</ItemGroup>
<ItemGroup>
<FunctionsPreservedDependencies Include="System.Text.Encoding.CodePages.dll" />
</ItemGroup>
List indent is not correct when exported to PDF. All indents start from the same position.
When importing a RTF document with bullet lists and exporting the RadFlowDocument back to RTF format the following result is observed:
- the bullet's left offset is changed
- the bullets color is also changed
Workaround: use the Telerik.Windows.Documents.FormatProviders.Rtf.RtfFormatProvider available in the Telerik.Windows.Documents.FormatProviders.Rtf.dll
XmlException is thrown when importing documents containing DAT files.
Workaround:1) Delete the files from the file structure before import:
RadFlowDocument flowDocument;
using (Stream str = new FileStream("input.docx", FileMode.OpenOrCreate))
{
MemoryStream ms = new MemoryStream();
str.CopyTo(ms);
ms.Seek(0, SeekOrigin.Begin);
using (ZipArchive archive = ZipArchive.Update(ms, null))
{
var zipEntries = archive.Entries;
// Skip glossary on importfor (int i = zipEntries.Count() - 1; i >= 0; i--)
{
var entry = zipEntries.ElementAt(i);
string entryName = entry.FullName;
if (Regex.IsMatch(entryName, @"\[trash\]"))
{
entry.Delete();
}
}
}
}
Restrict the TableCellProperties API of a style according to specification.
When table with table border without color set is created (the color is null), and the document is exported to PDF, ArgumentNullException is thrown.
Workaround: Explicitly set a color where the color is null.
private void PdfExport()
{
var tables = this.document.EnumerateChildrenOfType<Table>();
foreach (var table in tables)
{
TableBorders coloredClone = this.CopyTableBorders_SetColorWhenOmitted(table);
table.Borders = coloredClone;
using (Stream output = new FileStream(fileName, FileMode.OpenOrCreate))
{
provider.Export(this.document, output);
}
}
}
private TableBorders CopyTableBorders_SetColorWhenOmitted(Table table)
{
var leftBorder = new Border(table.Borders.Left.Thickness,
table.Borders.Left.Style,
table.Borders.Left.Color ?? new ThemableColor(Colors.Transparent),
table.Borders.Left.Shadow,
table.Borders.Left.Frame,
table.Borders.Left.Spacing);
var rightBorder = new Border(table.Borders.Right.Thickness,
table.Borders.Right.Style,
table.Borders.Right.Color ?? new ThemableColor(Colors.Transparent),
table.Borders.Right.Shadow,
table.Borders.Right.Frame,
table.Borders.Right.Spacing);
var bottomBorder = new Border(table.Borders.Bottom.Thickness,
table.Borders.Bottom.Style,
table.Borders.Bottom.Color ?? new ThemableColor(Colors.Transparent),
table.Borders.Bottom.Shadow,
table.Borders.Bottom.Frame,
table.Borders.Bottom.Spacing);
var topBorder = new Border(table.Borders.Top.Thickness,
table.Borders.Top.Style,
table.Borders.Top.Color ?? new ThemableColor(Colors.Transparent),
table.Borders.Top.Shadow,
table.Borders.Top.Frame,
table.Borders.Top.Spacing);
var insideHorizontalBorder = new Border(table.Borders.InsideHorizontal.Thickness,
table.Borders.InsideHorizontal.Style,
table.Borders.InsideHorizontal.Color ?? new ThemableColor(Colors.Transparent),
table.Borders.InsideHorizontal.Shadow,
table.Borders.InsideHorizontal.Frame,
table.Borders.InsideHorizontal.Spacing);
var insideVerticalBorder = new Border(table.Borders.InsideVertical.Thickness,
table.Borders.InsideVertical.Style,
table.Borders.InsideVertical.Color ?? new ThemableColor(Colors.Transparent),
table.Borders.InsideVertical.Shadow,
table.Borders.InsideVertical.Frame,
table.Borders.InsideVertical.Spacing);
var tableBorders = new TableBorders(leftBorder, topBorder, rightBorder, bottomBorder, insideHorizontalBorder, insideVerticalBorder);
return tableBorders;
}
Center alignment is not respected for list numbering.
Expected:
Actual:
When a document with multiple headings ( Heading 1) are imported and then exported, their type from letters is changed to numbers, for example:
Original content: Part A, Part B, Part C
Exported content: Part 1, Part 2, Part 3
The generated document looks OK before printing:
However, hitting the print preview button in MS Words leads to missing text in the fields:
