这属性太多了，挨个试也没找到答案，就是想启动程序后，没有那个虚线框，如图示，请高手指点。谢谢先

VB.NET code

' Draws the backgrounds for entire ListView items.Private Sub listView1_DrawItem(ByVal sender As Object, _    ByVal e As DrawListViewItemEventArgs) _    Handles listView1.DrawItem    If Not (e.State And ListViewItemStates.Selected) = 0 Then        ' Draw the background for a selected item.        e.Graphics.FillRectangle(Brushes.Maroon, e.Bounds)        e.DrawFocusRectangle()'这一行就是你说的虚线，删掉或注释掉就没有虚线了。    Else        ' Draw the background for an unselected item.        Dim brush As New LinearGradientBrush(e.Bounds, Color.Orange, _            Color.Maroon, LinearGradientMode.Horizontal)        Try            e.Graphics.FillRectangle(brush, e.Bounds)        Finally            brush.Dispose()        End Try    End If    ' Draw the item text for views other than the Details view.    If Not Me.listView1.View = View.Details Then        e.DrawText()    End IfEnd Sub
