StopRedraw

停止绘制ListView，通常在大量添加行的时候先执行StopRedraw，添加结束后再执行ResueRedraw恢复绘制，以提高效率。

示例

Dim lvw As WinForm.ListView = e.Form.Controls("ListView1")
lvw.View = ViewMode.SmallIcon
lvw.StopRedraw
For i As Integer = 1 To 1000
    Dim vr As WinForm.ListViewRow = lvw.Rows.Add()
    vr.Name = i
    vr.Text = "项目"  & i
Next
lvw.ResumeRedraw
