When importing HTML content to a RadFlowDocument and exporting it to PDF format, the following error message occurs:
System.ArgumentException: 'The document element is associated with another parent. (Parameter 'item')'
at Telerik.Windows.Documents.Fixed.Model.Collections.DocumentElementCollection`2.VerifyDocumentElementOnInsert(T item)
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 });HtmlFormatProvider: Styles are not correctly preserved when a <b> tag is applied to the same styled element.
Workaround: Apply bold through CSS instead of using <b>.
When imported in the WordsProcessing model, the current HTML doesn't respect the defined column width and all columns have identical width:
<colgroup>
<col span="1" style="width: 33.3302%;">
<col span="1" style="width: 17.5658%;">
<col span="1" style="width: 49.104%;">
</colgroup>Observed result:
Expected result:
Workaround: use the width property as follows:
<colgroup>
<col span="1" width="33.3302%">
<col span="1" width="17.5658%">
<col span="1" width="49.104%">
</colgroup>
