Latest version 2024.2.426:
Old version 2022.3.906:
Use the following code:
static void Main(string[] args)
{
Console.WriteLine("Test from 2022.3.906 to 2024.2.426.");
string html = @"<html>
<head>
<style type=""text/css"">
h1 {
background-color: red;
}
#highlight1{
background-color: blue;
}
.highlight2{
background-color: yellow;
}
</style>
</head>
<body>
<h1>H1 - This Works </h1>
<h2 id=""highlight1"">H2 with id selector. This works too.</h2>
<h3 class=""highlight2"">H3 with class selector. This didn't work</h3>
</body>
</html>";
Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider html_provider = new Telerik.Windows.Documents.Flow.FormatProviders.Html.HtmlFormatProvider();
RadFlowDocument document = html_provider.Import(html);
string html_output = "output.html";
using (Stream output = File.Create(html_output))
{
html_provider.Export(document, output);
}
Process.Start(new ProcessStartInfo() { FileName = html_output, UseShellExecute = true });
}
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
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
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>
The generated document looks OK before printing:
However, hitting the print preview button in MS Words leads to missing text in the fields:
This is the code snippet that reproduces the error:
RadFlowDocument flowDocument = new RadFlowDocument();
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(flowDocument);
Bookmark bookmark = new Bookmark(flowDocument, "Name");
editor.InsertInline(bookmark.BookmarkRangeStart);
Table table = editor.InsertTable(1, 2);
TableCell cell1 = table.Rows[0].Cells[0];
Paragraph cell_paragraph1 = cell1.Blocks.AddParagraph();
editor.MoveToParagraphStart(cell_paragraph1);
editor.InsertText("cell content 01");
TableCell cell2 = table.Rows[0].Cells[1];
Paragraph cell_paragraph2 = cell2.Blocks.AddParagraph();
editor.MoveToParagraphStart(cell_paragraph2);
editor.InsertText("cell content 02");
editor.MoveToTableEnd(table);
editor.InsertInline(bookmark.BookmarkRangeEnd);
RadFlowDocument newFlowDocument = new RadFlowDocument();
RadFlowDocumentEditor editor02 = new RadFlowDocumentEditor(newFlowDocument);
editor.InsertDocument(flowDocument);
Workaround: Insert one bookmark before the table and another one after the table:
RadFlowDocument flowDocument = new RadFlowDocument();
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(flowDocument);
//Bookmark bookmark = new Bookmark(flowDocument, "Name");
//editor.InsertInline(bookmark.BookmarkRangeStart);
editor.InsertBookmark("before");
Table table = editor.InsertTable(1, 2);
TableCell cell1 = table.Rows[0].Cells[0];
Paragraph cell_paragraph1 = cell1.Blocks.AddParagraph();
editor.MoveToParagraphStart(cell_paragraph1);
editor.InsertText("cell content 01");
TableCell cell2 = table.Rows[0].Cells[1];
Paragraph cell_paragraph2 = cell2.Blocks.AddParagraph();
editor.MoveToParagraphStart(cell_paragraph2);
editor.InsertText("cell content 02");
editor.MoveToTableEnd(table);
editor.InsertBookmark("after");
//editor.InsertInline(bookmark.BookmarkRangeEnd);
RadFlowDocument newFlowDocument = new RadFlowDocument();
RadFlowDocumentEditor editor02 = new RadFlowDocumentEditor(newFlowDocument);
editor.InsertDocument(flowDocument);
Use the code for inserting the code:
static void Main(string[] args)
{
Telerik.Windows.Documents.Flow.Model.RadFlowDocument templateDocument = GetDocument("Template.rtf");
Telerik.Windows.Documents.Flow.Model.RadFlowDocument contentDocument = GetDocument("Content.rtf");
InsertDocumentOptions options = new InsertDocumentOptions();
options.ConflictingStylesResolutionMode = ConflictingStylesResolutionMode.RenameSourceStyle;
options.InsertLastParagraphMarker = true;
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(templateDocument);
editor.InsertDocument(contentDocument, options);
string mergedDocumentFilePath ="MergeDocumentsWithWordsProcessing.rtf";
File.Delete(mergedDocumentFilePath);
WriteDocToFile(templateDocument, mergedDocumentFilePath);
}
private static Telerik.Windows.Documents.Flow.Model.RadFlowDocument GetDocument(string rtfFilePath)
{
Telerik.Windows.Documents.Flow.Model.RadFlowDocument document = null;
var rtfImporter = new Telerik.Windows.Documents.Flow.FormatProviders.Rtf.RtfFormatProvider();
using (Stream stream = File.OpenRead(rtfFilePath))
{
document = rtfImporter.Import(stream);
}
return document;
}
private static void WriteDocToFile(Telerik.Windows.Documents.Flow.Model.RadFlowDocument doc, string filename)
{
var rtfExporter = new Telerik.Windows.Documents.Flow.FormatProviders.Rtf.RtfFormatProvider();
string rtfText = rtfExporter.Export(doc);
File.WriteAllText(filename, rtfText);
Process.Start(filename);
}
Observed result: The After spacing is reset
Expected result: keep the style settings from the original documents.
