Webbrowser control drag drop Multiple Files

In WebBrowser control of .NET Winform, there is no drag & drop event. But we had a requirement to catch the dropped files. By using beforenavigate event, we can catch only one dropped file and not able to pick up all the dropped files.

The simple trick is to disable the Web browser control while dropping, so that the form dragdrop event will be fired, from where we can get all the files. But there is no disable property for Webbrowser control. To overcome that, place the webbrowser control inside a Panel & disable the panel, so that the webbrowser control will also be disabled.

Next question will be, When to disable the Panel control ?
Form Activate / Deactivate, since while we start dragging a file obviously the form will be deactivated & we can disable the Panel. On(after) drop, the form will be activated & can enable the Panel control.

The code is :
1. In Form1, placed the webbrowser control in the “Panel1″ panel control.
2. Applied the following code in your form

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load      Me.AllowDrop = True End Sub Private Sub Form1_DragDrop(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles Me.DragDrop      Dim files() As String = e.Data.GetData(DataFormats.FileDrop)      For Each filePath In files           MsgBox(filePath)      Next End Sub Private Sub Form1_DragEnter(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles Me.DragEnter      If e.Data.GetDataPresent(DataFormats.FileDrop) Then           e.Effect = DragDropEffects.Copy      End If End Sub Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated      ' To Enable Web Browser control      Panel1.Enabled = True End Sub Private Sub Form1_Deactivate(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Deactivate      ' To Disable Web Browser control      Panel1.Enabled = False End Sub
