    End Sub

    Private Sub ToolboxControl_PlaceItemAtDefaultLocation(ByVal sender As Object, ByVal e As PlaceToolboxItemAtDefaultLocationEventArgs)
        If e.Item IsNot Nothing AndAlso String.IsNullOrEmpty(e.Item.DisplayName) Then
            Windows.Forms.MessageBox.Show(String.Format("Item: {0} added", e.Item.DisplayName))

Remarks

You can associate the Form designer with the ToolboxControl object by setting FormDesignerControl property. This allows users to place components onto the designer's surface, by dragging them from the toolbox.
