  Hi viliescu i'm giving like this but it shows like : The name 'LoadFile' does not exist in the current context , i'm using Feb2006 ctp. Is there any alternate solution for this and also how to apply alignment properties like right, left , justify for richtext box content

  thanx for reply

  Microsoft.Win32.OpenFileDialog ofd = new Microsoft.Win32.OpenFileDialog();
  ofd.Filter = "Text Files (*.txt; *.xaml; *.rtf)|*.txt;*.xaml;*.rtf";
  ofd.Multiselect = false;
  if (ofd.ShowDialog() == true)
  {
  LoadFile(ofd.SafeFileName, myTextBox);
  }

  Several things to note here.

  Looks like you are extracting the text dataformat from the problem you describing.

  From the code provided, it can be seen that the rtf format is retrieved on reading a file with the .rtf extension Otherwise, the text format is read.

  If the problem is not the above, its likely that the rtf being generated is faulty. Simple way to test this is to copy the content from the file and paste it in RichTextbox. If it renders incorrectly you are generating wrong rtf.

  those are static functions provided in the blog :)

  as for alignment you could set the TextAlignment property on the FlowDocument of the richtextbox
