I am trying to adapt this code but in my form it doesnt seem to trigger the event

any suggestions

vb Code:

private void listBox1_DragEnter(object sender, System.Windows.Forms.DragEventArgs e)
        {
            // make sure they're actually dropping files (not text or anything else)
            if( e.Data.GetDataPresent(DataFormats.FileDrop, false) == true )
                // allow them to continue
                // (without this, the cursor stays a "NO" symbol
                e.Effect = DragDropEffects.All;
        }
 
        private void listBox1_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)
        {
            // transfer the filenames to a string array
            // (yes, everything to the left of the "=" can be put in the 
            // foreach loop in place of "files", but this is easier to understand.)
            string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);
 
            // loop through the string array, adding each filename to the ListBox
            foreach( string file in files )
            {
                listBox1.Items.Add(file);
            }
        }
