Solution
To insert HTML content at specific locations in a RadFlowDocument, follow these steps:
Use the HtmlFormatProvider to import HTML content into a RadFlowDocument.
Use the RadFlowDocumentEditor to insert the imported document (step 1) into a specific location in your target document.
Example:
RadFlowDocument originalDocument = new RadFlowDocument();
DocxFormatProvider docxProvider = new DocxFormatProvider();
originalDocument = docxProvider.Import(File.ReadAllBytes("original.docx"), TimeSpan.FromSeconds(10));
HtmlFormatProvider htmlProvider = new HtmlFormatProvider();
RadFlowDocument htmlDocument = htmlProvider.Import(File.ReadAllText("content.html"), TimeSpan.FromSeconds(10));
// Get paragraphs from the imported document
var importedParagraphs = htmlDocument.EnumerateChildrenOfType<Paragraph>().ToList();
// Move editor to the start of the target paragraph
RadFlowDocumentEditor editor = new RadFlowDocumentEditor(originalDocument);
var tableCells = originalDocument.EnumerateChildrenOfType<TableCell>().ToList();
TableCell cell = tableCells[3] as TableCell;
editor.MoveToParagraphStart(cell.Blocks.First() as Paragraph);
editor.InsertDocument(htmlDocument);
string outputFilePath = "output.docx";
File.Delete(outputFilePath);
using (Stream output = File.OpenWrite(outputFilePath))
{
docxProvider.Export(originalDocument, output, TimeSpan.FromSeconds(10));
}
Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });
Additional Notes
- To target specific locations in the document, use the RadFlowDocumentEditor to navigate to the desired position.
- Ensure the original document and imported HTML content are compatible in terms of styles and formatting.
