OnDrop does not use Modified Text

[akash3456]

Is there any chance of an example please???

Sure.

In the OnLoad:

DataObject.AddPastingHandler(AvalonEditBox, OnPaste);

And then later:

private void OnPaste(object sender, DataObjectPastingEventArgs e)
{
    var isText = e.SourceDataObject.GetDataPresent(DataFormats.UnicodeText, true);
    if (!isText) return;
    var text = (string)e.SourceDataObject.GetData(DataFormats.UnicodeText);

    if (Uri.IsWellFormedUri(text))
    {
        var dataObject = new DataObject();
        dataObject.SetData(DataFormats.UnicodeText, string.Format("<{0}>", text);
        e.DataObject = dataObject;
    }
}

To reproduce, drag and drop an image from a web browser. By default, AE will paste the link in. I want to modify the paste text to be surrounded by less than, greater than symbols (<link>). This is for use in my Markdown Editor (http://mike-ward.net/markdownedit).

If I create a new dataobject (as per the example) and return it, the original dataobject's text is used, not the modified text.

I can achieve my desired functionality by canceling the paste command and issuing a new paste with the modified text. It works but feels a bit wrong.

Hope that clarifies the issue.
