Using RtfFormatProvider

RtfFormatProvider makes it easy to import and export RadDocument to/from RTF format, preserving the entire document structure and formatting.

All you have to do in order to use RtfFormatProvider is to add references to:

  • Telerik.Windows.Documents.FormatProviders.Rtf.dll

Import

In order to import an RTF document, you need to use the Import() method of RtfFormatProvider.

The code from Example 1 shows how to use RtfFormatProvider to import an RTF document from a file.

Example 1: Import document from a file

RtfFormatProvider provider = new RtfFormatProvider();
using (Stream input = File.OpenRead("Sample.rtf"))
{
    RadDocument document = provider.Import(input);
}

And here is how you can import a document from string containing the RTF document:

Example 2: Import document from a string

RtfFormatProvider provider = new RtfFormatProvider();
RadDocument document = provider.Import(input);

The resulting RadDocument can be used like any code-generated document.

Export

In order to export a document to RTF, you need to use the Export() method of RtfFormatProvider.

Example 3 shows how to use RtfFormatProvider to export RadDocument to a file.

Example 3: Export a document to a file

RtfFormatProvider provider = new RtfFormatProvider();
using (Stream output = File.Create("sample.rtf"))
{
    RadDocument document = CreateRadDocument();
    provider.Export(document, output);
}

You can also export the document to a string and preserve it in a database.

Example 4: Export a document to a string

RtfFormatProvider provider = new RtfFormatProvider();
RadDocument document = CreateRadDocument();
string output = provider.Export(document);

The resulting documents can be opened in any application that supports RTF documents.
