<RichTextBox x:Name="text_rich" > <FlowDocument > <Paragraph/> </FlowDocument> </RichTextBox> When copying a picture (file) from the disk does not work. It works only when copying a picture from a text document.
So it is inserted from the file and how from the buffer?
This is how the file is inserted from the file, and this image file is needed from the buffer.
BitmapImage bitmap = new BitmapImage(new Uri(@"z:\DOWNLOADS\avatar145693_6.gif")); Clipboard.SetImage(bitmap); text_rich.Paste();
