I wish to drag a file from a folder on the desktop and drop it into a RichTextBox in my app. It works, but all I really need is the path & filename of the dropped file, which I can get from the dropped event.

However, my RichTextBox always get the big icon of the file (an empty square with the filename to be exact) dropped into the dropped mouse location. How can I prevent this icon from appearing, yet still be able to catch the path/file of the dropped file(s)?

Yes, the behavior is EXACTLY that of Wordpad.
You mentioning this made me think that the problem is in the RichTextBox itself, not the drag and drop code that was already working. A close look through the RTB properties reveals "EnableAutoDragDrop". This was set to true. Apparently this will perform a DD operations independently of your code, and by default displays the aforementioned icon.

Switching EnableAutoDragDrop to be False prevents the automatic attempt at DD and lets you code perform by itself. This is the solution.

Thanks for the assist!

        void Form2_DragDrop(object sender, DragEventArgs e)

  label1.Text = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString();

void Form2_DragEnter(object sender, DragEventArgs e)

if (e.Data.GetDataPresent(DataFormats.FileDrop))

DragDropEffects.Link;

else e.Effect = DragDropEffects.None;

The designer hides all the D+D properties and events for the RTB. Not sure why, it works fine if I set them in code:

public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e) {
richTextBox1.AllowDrop = true;
richTextBox1.DragEnter += richTextBox1_DragEnter;
richTextBox1.DragDrop += richTextBox1_DragDrop;
}
private void richTextBox1_DragEnter(object sender, DragEventArgs e) {
if (e.Data.GetDataPresent(DataFormats.FileDrop)) e.Effect = DragDropEffects.Link;
else e.Effect = DragDropEffects.None;
}
private void richTextBox1_DragDrop(object sender, DragEventArgs e) {
richTextBox1.Text += ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString();
}
}

This does not work, as it does not prevent the icon from appearing in the RichTextBox.

Your code (and that of the previous poster) seems to have the exact same effect as mine--I should stress that I have Drag&Drop *working*--the problem is that I want to *prevent* the "icon" from being dropped into my rich text box, yet I *need* drag & drop operating so that I can programmatically get the filename that was dropped. Emphasis on *not getting the icon*.

Perhaps this isn't a drag&drop issues, but a richtextbox issue?
