如何在c＃中设置PropertyGrid项的长度？ [英] How to set length for PropertyGrid items in c#?

问题描述

例如我有1个项目：如何设置Item1 = 80最大长度的最大长度

 [类别（< span class =code-keyword> All ）] 
 [Description（Name）] 
 [ReadOnly（false）] 
 [DisplayName（sPropName）] 
 [XmlAttribute] 
  public 覆盖字符串标签
 {
 get 
 {
  return  base.Label; 
} 
  set  
 {
 
 value = value.TrimEnd（）; ignorieren 
 
 
  if （value.length>  80 ） 
 {
 //这里我要用户 不  to 允许 写入超过 80   char  
 当 用户写一些 in 名称feild max Length  80 我想要用户  允许
 
} 
 
 
} 
} 

解决方案

For Strings

对于整数



http： //msdn.microsoft.com/en-us/library/system.configuration.integervalidatorattribute.aspx [ ^ ]

  //  将第3列的大小设置为250  
 此 .gridDataBoundGrid1 .AllowResizeToFit =  false ; 
 此 .gridDataBoundGrid1.Model.ColWidths [ 3 ] =  250  

For example I have 1 item: How can I set max length for Item1 = 80 max length

[Category(All)]
       [Description(Name)]
       [ReadOnly(false)]
       [DisplayName(sPropName)]
       [XmlAttribute]
       public override string Label
       {
           get
           {
               return base.Label;
           }
           set
           {

               value = value.TrimEnd();   ignorieren


               if (value.length > 80)
               {
                //here I want user not to allow to write more than 80 char
                  when user write something in  Name feild max Length 80 i want a user to allow

               }


           }
       }

For Integers

//set size of column 3 to 250
this.gridDataBoundGrid1.AllowResizeToFit = false;
this.gridDataBoundGrid1.Model.ColWidths[3] = 250;
