Using DocxFormatProvider
DocxFormatProvider makes it easy to import and export RadRichTextBox to/from DOCX format, preserving the entire document structure and formatting.
All you have to do in order to use DocxFormatProvider is to add a reference to Telerik.Windows.Documents.FormatProviders.OpenXml.dll.
Import
In order to import a .docx file, you need to use the Import() method of DocxFormatProvider. The code in Example 1 shows how to use DocxFormatProvider to import a DOCX document from a file.
Example 1: Import document from a file
Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider provider = new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
using (FileStream inputStream = new FileStream("Sample.docx",FileMode.Open))
{
this.radRichTextBox.Document = provider.Import(inputStream);
}And here is how you can import a document from byte array containing the docx document:
Example 2: Import document from a byte array
Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider provider = new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
RadDocument document = provider.Import(input);Export
In order to export a document to DOCX, you need to use the Export() method of DocxFormatProvider. Example 2 shows how to use DocxFormatProvider to export RadDocument to a file.
Example 3: Export document to a file
Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider provider = new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
using (FileStream output = new FileStream("Sample.docx",FileMode.OpenOrCreate))
{
RadDocument document = this.radRichTextBox.Document;
provider.Export(document, output);
}You can also export the document to a byte array and preserve it in a database.
Example 4: Export a document to a byte array
Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider provider = new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
RadDocument document = CreateRadDocument();
byte[] output = provider.Export(document);The resulting documents can be opened in any application that supports DOCX documents.
owever, the format providers cannot be used in XAML and you have to implement a logic that will call their Import() and Export() methods. This is something that you might not want to be concerned with when using RadRichTextBox in a data bound scenarios. For such cases, the DataProvider classes are used. They wrap the FormatProviders' functionality and allow its usage in XAML.
