如何代表id获取名称.. [英] How to Get the name on behalf of id..

问题描述

你好，



我在文本框中有一个ID，我想代表id，名字应该显示在另一个文本框下面。我创建了一个方法但不知道在哪里调用它..请帮助我......

每当我选择id时，下面的文本框应该自动填充该特定Id的名称..





这是我的Id文本框

 <   asp：TextBox     ID   =  txtlinemanager   宽度  =  120    CssClass   =  nonwatermarked    runat   = 服务器 >  <   / asp：TextBox  >  
 <   asp：ImageButton     ID   =  imgbtnbusinessheadid    runat   =  server   工具提示  = 点击此处进行搜索......  
   
                                                         ImageUrl   = 〜/ Icons / search-button .gif    OnClientClick   =' 返回OpenPopup（经理）;  

这是名称文本框

 <   div     class   =  txtLTitleMenuEdit >  
受托人姓名<   / div  >  
 <   div     class   =  lblfullname >  
 <   asp：TextBox     ID   =  txtTrusteeName    ReadOnly   =  true   宽度  =  300    CssClass   = 非加水印的  
   
                                    < span class =code-attribute>       runat   =  server   >  <   div     class   =  divnewline >  
 <   / div  >  

我创建的方法是

 受保护  void  TrusteeName（）
 {
 使用 （SqlConnection con =  new  SqlConnection（connectionstring））
 {
  using （SqlCommand cmd =  new  SqlCommand（ 从表中选择trusteename，其中Id =' + txtlinemanager.text +  '，con））
 {
 使用（SqlDataAdapter adapt =  new  SqlDataAdapter（cmd））
 {
 DataSet ds =  new  DataSet（）; 
 adapt.Fill（ds）; 
 txttrusteename.text = ds.Tables [ 0 ]。行[ 0 ] [  trusteename]。ToString（）; 
} 
 
} 
} 
} 
 

解决方案

< blockquote>在你的第一个文本框中将autopostback设为True，

并在textchange_event上编写你的代码

       {
           using (SqlCommand cmd = new SqlCommand("select trusteename from  table where Id='" + txtlinemanager.text + "'", con))
           {
               using (SqlDataAdapter adapt = new SqlDataAdapter(cmd))
               {
                   DataSet ds=new DataSet();
                   adapt.Fill(ds);
                   txttrusteename.text = ds.Tables[0].Rows[0]["trusteename"].ToString();
               }

           }
       }
   }

in your first textbox make autopostback as True,
and write your code on textchange_event
