Hi guys,
I have save file in rtf from Richtextbox (okay it saves). But when i open this file manually it's asking me to save changes but i am not changed or edit anything.
why this happens ?
Is SaveFile() doesn't save file properly.

Are you using the SaveFile method like this?
richTextBox1.SaveFile("C:\MyDocument.rtf", RichTextBoxStreamType.RichText)
