RichTextBox DoDragDrop question

[drachon]

I have added the call to the DoDragDrop within the RTB's MouseDown event to
initiate the drag. But this causes the doubleclick to selected a word within
the RTB to not work. Any ideas?

sample code:

private void sourceTextBox_MouseDown(object sender,
System.Windows.Forms.MouseEventArgs e)
{
string plainText;

// get the mouse cordintates within the text box...
Point mouse = new Point(e.X, e.Y);

// only start drag if mouse click is inside previously selected text
if(MousePointerInSelection(mouse, this.sourceTextBox.SelectionStart,
this.sourceTextBox.SelectionLength))
{
plainText = this.sourceTextBox.SelectedText.ToString();
DragDropEffects dde = this.sourceTextBox.DoDragDrop(plainText,
DragDropEffects.Copy);
}
}

Thanks
drachon.
