WPF Richtextbox opens RTF file as plain text
I am trying to open a file to view the content as plain text inside RichTextbox
on click Button
. Nothing seems to work.
private void loadFile_Click(object sender, RoutedEventArgs e)
{
OpenFileDialog openFile1 = new OpenFileDialog();
openFile1.FileName = "Document";
openFile1.DefaultExt = "*.*";
openFile1.Filter = "All Files|*.*|Rich Text Format|*.rtf|Word Document|*.docx|Word 97-2003 Document|*.doc";
if (openFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK && openFile1.FileName.Length > 0)
{
//richTextbox1.Document.ContentStart = File.ReadAllText(openFile1.FileName);
}
}
I am using WPF and the LoadFile method is not working. I would like to be able to select a file from OpenFileDialog
and load it as plain text inside RichTextbox
. Without looking at added code from file formats.
The behavior I like is like opening a .rtf, selecting all the text, and pasting that result into RichTextbox
. How can I do this with a button click?

Use TextRange
andFileStream
if (openFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK )
{
TextRange range;
System.IO.FileStream fStream;
if (System.IO.File.Exists(openFile1.FileName))
{
range = new TextRange(RichTextBox1.Document.ContentStart, RichTextBox1.Document.ContentEnd);
fStream = new System.IO.FileStream(openFile1.FileName, System.IO.FileMode.OpenOrCreate);
range.Load(fStream, System.Windows.DataFormats.Rtf );
fStream.Close();
}
}

Like @AbZy, you need to clear the formatting first:
private void loadFile_Click(object sender, RoutedEventArgs routedEventArgs)
{
OpenFileDialog openFile1 = new OpenFileDialog();
openFile1.FileName = "Document";
openFile1.DefaultExt = "*.*";
openFile1.Filter = "All Files|*.*|Rich Text Format|*.rtf|Word Document|*.docx|Word 97-2003 Document|*.doc";
if (openFile1.ShowDialog() == true)
{
var range = new TextRange(rtf.Document.ContentStart, rtf.Document.ContentEnd);
using (var fStream = new FileStream(openFile1.FileName, FileMode.OpenOrCreate))
{
// load as RTF, text is formatted
range.Load(fStream, DataFormats.Rtf);
fStream.Close();
}
// clear the formatting, turning into plain text
range.ClearAllProperties();
}
}
