Hi!

Snapshots from Snagit, Adobe and other softwares does not work.
Picture does not show up.

As well available as a Jing (.swf) file:

Hi Anders,

Thank you for getting to us with this!

The unexpected behavior which you have experienced is a known issue. The issue is already added to our to-do list. We can assure you that we are doing our best to develop all enhancements to the control as soon as possible. You able to track its implementation progress using the Feedback & Ideas portal – pasting snapshots issues.

The issue is specific to the program which you are copying the image from. Please take a look at this forum post for a reference.

However, we have also found a workaround for the problem and it should display correctly snapshots. For using it, I would recommend you to subscribe to the CommandExecuting event of RadRichTextBox and handling it in the following way:
...
       this.editor.CommandExecuting += PasteImageCommand;
...
        private void PasteImageCommand(object sender, CommandExecutingEventArgs e)
        {
            PasteCommand command = e.Command as PasteCommand;
            if (command != null && Clipboard.ContainsImage())
            {
                BitmapSource imageSource = Clipboard.GetImage();
                using (MemoryStream stream = new MemoryStream())
                {
                    JpegBitmapEncoder encoder = new JpegBitmapEncoder();
                    encoder.Frames.Add(BitmapFrame.Create(imageSource));
                    encoder.Save(stream);
                    stream.Seek(0, SeekOrigin.Begin);
                    ((RadRichTextBox)sender).InsertImage(stream, "jpeg");
                    e.Cancel = true;
                }
            }
        }

I hope this helps. 

All the best,
