intercepting and altering pasted content

[Michael]

Hi all,

I've got a requirement to modify the styling of rich text that's pasted into my radrichtextbox. The following code works, but it hangs the UI when it's run on the main thread, and ClipboardEx.GetDocumentFromClipboard is unhappy when it's not run on the main thread ( something like this https://stackoverflow.com/questions/15913275/backgroundworker-and-clipboard )

Has anybody found a way around this?

 

        private void EditorTextBoxCommandExecuting(object sender, CommandExecutingEventArgs e)
        {
            if (e.Command is PasteCommand)
            {
                DocumentFragment fragment = ClipboardEx
                        .GetDocumentFromClipboard(
                            "RadDocumentGUID"); //copy pasting from a RadRichTextBox, keep the paragraphs as they are
                RemoveStylingFromFragment(fragment);
                Editor.InsertFragment(fragment);

       }

}

Hello Michael,

Could you please elaborate more on the scenario that you have on your end? Indeed, the code should be run on the main thread, but it shouldn't hang it and I am currently not sure what might cause a similar behavior. Is it always reproducible with different a data or it is related to specific content?

Regards,
