列表视图中的闪烁问题 [英] Flickering problem in listview

问题描述

我做了很多谷歌搜索，但我没有得到正确的解决方案，以阻止在listview中闪烁，因为我在richtextbox中停止闪烁，但我没有停止在列表视图中闪烁。



以下代码我以前在Richtexbox中停止闪烁...它对我有用..

 [System.Runtime。 InteropServices.DllImport（  user32.dll）] 
  private   extern   static   IntPtr  SendMessage（ IntPtr  hWnd， int  msg， IntPtr  wp， IntPtr  lp）; 
 
  //  每2秒后重新加载代码...  
 
 SendMessage（RichText_MessageData.Handle，0xb，（ IntPtr ） 0 ， IntPtr的 .Zero）; 
  //  在richtextbox中进行一些更改...  
 
 SendMessage（RichText_MessageData.Handle，0xb，（ IntPtr ） 1 ， IntPtr的 .Zero）; 
 RichText_MessageData.Invalidate（）; 

我使用下面的代码来停止闪烁在listview中.....它没有用..

 SendMessage（lv_employeelist.Handle，0xb，（ IntPtr ） 0 ， IntPtr  .Zero）; 
  //  每2秒在listview中添加一行..  
 SendMessage（ lv_employeelist.Handle，0xb，（ IntPtr ） 1 ， IntPtr  .Zero）; 
 lv_employeelist.Invalidate（）; 

我在这做错了什么...

解决方案

您好，您可能需要考虑运行代码以在单独的线程中将UI更新为主执行线程。



之前我遇到过与Winforms类似的问题，并且发现您描述的闪烁行为通常是在您尝试在执行其他操作时更新UI时引起的。

I have do lots googling but I did not get right solution to stop flickering in listview as I am stop flickering in richtextbox but I did not stop flickering in listview.

following code I used to stop flickering in Richtexbox...it is works for me..

[System.Runtime.InteropServices.DllImport("user32.dll")]
        private extern static IntPtr SendMessage(IntPtr hWnd, int msg, IntPtr wp, IntPtr lp);

//below code reloaded after every 2 seconds...

SendMessage(RichText_MessageData.Handle, 0xb, (IntPtr)0, IntPtr.Zero);
//doing some changes in richtextbox...

SendMessage(RichText_MessageData.Handle, 0xb, (IntPtr)1, IntPtr.Zero);
            RichText_MessageData.Invalidate();

and I am using below code to stop flickering in listview.....It is not worked..

SendMessage(lv_employeelist.Handle, 0xb, (IntPtr)0, IntPtr.Zero);
//adding rows in listview in every 2 seconds..
SendMessage(lv_employeelist.Handle, 0xb, (IntPtr)1, IntPtr.Zero);
            lv_employeelist.Invalidate();

What I am done here wrong...

解决方案

Hi, you might want to consider running code to update your UI in a separate thread to the main thread of execution.

I have experienced similar problems with Winforms before and have found that the flickering behaviour you described is usually caused when you're trying to update your UI whilst performing another operation.
