如何加快Windows窗体中加载控件的过程。 [英] How to speed up the process of loading controls in windows form.

问题描述

大家好，



任何人都可以告诉我如何加快将控件加载到窗体中的过程，我有一个窗体，我在其中添加了一个flowlayoutpanel&进入它的几个按钮。这根据用户所需的按钮而不断变化。基本上它有25排& 4列或有时12行& 4列。用户可以选择这些选项中的任何一个，一旦用户选择或点击特定选项，所有先前存在的形成被清除&选择1形成。在此期间，观察到巨大的延迟。如何提高这种操作的速度....？我已将doublebuffered设置为true但仍然没有用。



我也试过这段代码，

 受保护 覆盖 CreateParams CreateParams 
 {
  get  
 {
  var  parms = 碱 .CreateParams; 
 parms.Style& = ~0x08000000; 
  return  parms; 
} 
} 

一切都是徒劳的。所以任何帮助将不胜感激。



提前谢谢。

解决方案

我可以建议两个选项：

1.使用 SuspendLayout 和 ResumeLayout 方法

< pre lang =cs> flowPanel.SuspendLayout（）;
flowPanel.Controls.Clear（）;
// 在此处向flowPanel添加控件
flowPanel.ResumeLayout（）;

2.删除当前的flowPanel并创建一个具有相同属性的新窗口

  //   this =当前表单 
 此 .SuspendLayout（）; 
  this  .Controls.Remove（flowPanel）; 
 
  var  fp =  new  FlowLayoutPanel（）; 
 fp.Location =  new 点（ 100 ， 10 ）; 
 fp.Size =  new 大小（ 200 ， 200 ）; 
  //  设置其他fp属性 
 
  //  在此处向fp添加控件 
 
  this  .Controls.Add（FP）; 
  this  .ResumeLayout（）; 

Hi all,

Can anybody tell me how to speed up the process of loading controls into windows form, i have a windows form in which i have added a flowlayoutpanel & few buttons into it. This keeps varying based on the buttons required by the user. Basically it has 25 rows & 4 columns or sometimes 12 row & 4 columns. The user can choose any of these options, once the user selects or clicks on the particular option, all the previously present formation is cleared & chosen 1 is formed. During this time a huge delay is observed. How to increase the speed of such operation....? I have set doublebuffered to true but still no use.

Also i tried with this piece of code,

protected override CreateParams CreateParams
     {
         get
         {
             var parms = base.CreateParams;
             parms.Style &= ~0x08000000; 
             return parms;
         }
     }

All in vain. So any help will be appreciated.

Thanks in advance.

解决方案

i can suggest two options:
1. use SuspendLayout and ResumeLayout methods

flowPanel.SuspendLayout();
flowPanel.Controls.Clear();
// add controls to flowPanel here
flowPanel.ResumeLayout();

2. remove current flowPanel and create a new one with the same properties

// this = current form
this.SuspendLayout();
this.Controls.Remove(flowPanel);

var fp = new FlowLayoutPanel();
fp.Location = new Point(100,10);
fp.Size = new Size(200,200); 
// set other fp properties

// add controls to fp here

this.Controls.Add(fp);
this.ResumeLayout();
