There was a recent
question on StackOverflow asking how to drag content from a rich text box and drop it into windows explorer to create a file. I did some digging and found that this was surprisingly easy to do. The thing to understand is that Explorer drag and drop expects the file to exist. So the solution I came up with was when the mouse leaves the RTB, if the left button is down, we save a temporary file and then setup the drag and drop.
private void richTextBox1_MouseLeave_1(object sender, EventArgs e)
{
// If the left mouse button is down when leaving the rtb
if (MouseButtons == MouseButtons.Left)
{
// Write everything to a temp file.
System.IO.File.WriteAllText(@"c:\Temp\helloWorld.rtf", richTextBox1.SelectedRtf);
string[] filenames = { @"c:\Temp\helloWorld.rtf" };
DataObject obj = new DataObject();
// Set the drag drop data with the FileDrop format
obj.SetData(DataFormats.FileDrop, filenames);
// Start the drag drop effect
DoDragDrop(obj, DragDropEffects.All);
}
}

That's it. Now you can highlight some text in the RTB and drag it out to a folder and it will create a file called helloworld.rtf.
