如何为控件及其子控件暂停绘画？

在我之前的工作中，我们一直在努力获取丰富的UI应用程序以立即流畅地绘画。我们正在使用标准的.Net控件，自定义控件和devexpress控件。

经过大量的搜索和反射器使用后，我遇到了WM_SETREDRAW
win32消息。当您更新控件时，这实际上会停止控件绘图，并且可以将IIRC应用于父/包含面板。

这是一个非常简单的类，演示如何使用此消息：

class DrawingControl{    [Dllimport("user32.dll")]    public static extern int SendMessage(IntPtr hWnd, Int32 wMsg, bool wParam, Int32 lParam);    private const int WM_SETREDRAW = 11;    public static void SuspendDrawing( Control parent )    {        SendMessage(parent.Handle, WM_SETREDRAW, false, 0);    }    public static void ResumeDrawing( Control parent )    {        SendMessage(parent.Handle, WM_SETREDRAW, true, 0);        parent.Refresh();    }}

有关此内容的讨论更充分-Google for C＃和WM_SETREDRAW，例如

C＃抖动

暂停版式

并且可能与之相关的是VB中的类似示例：

Public Module Extensions    <Dllimport("user32.dll")>    Private Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As Boolean, ByVal lParam As IntPtr) As Integer    End Function    Private Const WM_SETREDRAW As Integer = 11    ' Extension methods for Control    <Extension()>    Public Sub ResumeDrawing(ByVal Target As Control, ByVal Redraw As Boolean)        SendMessage(Target.Handle, WM_SETREDRAW, True, 0)        If Redraw Then Target.Refresh()        End If    End Sub    <Extension()>    Public Sub SuspendDrawing(ByVal Target As Control)        SendMessage(Target.Handle, WM_SETREDRAW, False, 0)    End Sub    <Extension()>    Public Sub ResumeDrawing(ByVal Target As Control)        ResumeDrawing(Target, True)    End SubEnd Module
