Drag and Drop using C#

Posted on September 3rd, 2009 in C#, Tutorials | 6 Comments »

I was working on an App and needed Drag & Drop support for it. I thought it’ll be complicated but its very easy. Here’s how its done:

For this tutorial I’ll be using a listBox. You can use any control but make sure you set the “AllowDrop” to “true“.

Checking what has been dragged

Select the listBox and add the DragEnter event.

Add this code:

private void listBox1_DragEnter(object sender, System.Windows.Forms.DragEventArgs e)

 {

 // This will make sure that a file has been dropped and not text,folders or something else

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

 {

 // This will allow the files to be dragged into the control

 e.Effect = DragDropEffects.All;

 }

 }

The above code first makes sure that files are dragged and not anything else. And then allows the files to be dragged into the control.
