 CS代码：

  
    

   
     
   
     1 
   
      
   
     foreach
   
      (DataRow r 
   
     in
   
      ds.Tables[
   
     0
   
     ].Rows)

   
     2 
   
      {

   
     3 
   
      ComboBox1.Items.Add(
   
     new
   
      Coolite.Ext.Web.ListItem(r[
   
     1
   
     ].ToString(), r[
   
     0
   
     ].ToString()));

   
     4 
   
      }
  
    

用这种方式时，页面使用jsonreader或ArrayReader均可；

 

或者以下方式绑定：

cs代码:

   
     

    
      
    
      1 
    
       　　　　　 Store1.DataSource 
    
      =
    
       ds.Tables[
    
      0
    
      ];

    
      2 
    
       Store1.DataBind();

    
      3 
    
       ComboBox1.ValueField 
    
      =
    
       
    
      "
    
      employee_no
    
      "
    
      ;

    
      4 
    
       ComboBox1.DisplayField 
    
      =
    
       
    
      "
    
      employee_display_name
    
      "
    
      ;

    
      5 
    
       
    
      //
    
      ComboBox1.StoreID = Store1.ClientID;
    
      

    
      6 
    
       
    
       ComboBox1.DataBind();
   
     

 用这种方式时，页面使用jsonreader；StoreID 如果页面指定，则此处可不加ComboBox1.StoreID = Store1.ClientID;
