Pasting MS Word Formatted Fragments

[James Daresta]

Trying to figure out the best way via code to paste from a word document (using interop) a fragment of formatted text to a RichTextEditor as Html that is filtered. I can easily just paste, but then it seems I get a whole bunch of Word specific format. I want to paste filtered text. How would I go about this?

Hi James,

You could filter the content through the ClipboardStringFilter property of the clipboard handlers. For more details on thе available settings, please refer to the Clipboard Support help article.

In case you need to customize the default paste behavior, you could subscribe to the CommandExecuting event and change the PasteCommand. The ClipboardEx class allows you obtain the contents of the Clipboard. Once you get this content, you can modify it and insert it in the document according to your preferences. Here is a simple example:

private void RadRichTextBox_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)
{
    if (e.Command is PasteCommand)
    {
        // Stop the default paste command
        e.Cancel = true;

        // Get the contents of the clipboard
        DocumentFragment documentFragment = ClipboardEx.GetDocument();
        RadDocument document = documentFragment.ToDocument();

        // Apply the desired changes
        RadDocumentEditor editor = new RadDocumentEditor(document);
        editor.InsertInline(new Break(BreakType.LineBreak));
        document.Selection.SelectAll();

        // Insert in RadRichTextBox's document
        this.radRichTextBox.InsertFragment(new DocumentFragment(document.Selection));
    }
}

Hope this helps.
