Using TxtFormatProvider

Updated on Feb 19, 2026

TxtFormatProvider makes it easy to import and export RadFlowDocument to/from plain text format, preserving the document structure.

All you have to do in order to use TxtFormatProvider is add references to the packages listed below:

• Telerik.Windows.Documents.Core
• Telerik.Windows.Documents.Flow

Import

In order to import a plain text document, you need to use the Import() method of TxtFormatProvider.

Example 1 shows how to use TxtFormatProvider to import a document from a file.

Example 1: Import document from a file

c#

TxtFormatProvider provider = new TxtFormatProvider();
using (Stream input = File.OpenRead("Sample.txt"))
{
    RadFlowDocument document = provider.Import(input, TimeSpan.FromSeconds(10));
}

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

Example 2: Import document from a string

c#

TxtFormatProvider provider = new TxtFormatProvider();
string input = File.ReadAllText("sample.txt");
RadFlowDocument document = provider.Import(input, TimeSpan.FromSeconds(10));

The resulting RadFlowDocument can be manipulated like any code-generated document.

Export

In order to export a document to plain text, you need to use the Export() method of TxtFormatProvider.

Example 3 shows how to use TxtFormatProvider to export RadFlowDocument to a file.

Example 3: Export a document to a file

TxtFormatProvider provider = new TxtFormatProvider();
using (Stream output = File.OpenWrite("sample.txt"))
{
    RadFlowDocument document = CreateRadFlowDocument();

}

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