Gridview determines an object class

1. Create an object class named customer first. The Code is as follows:

  using  system;  using  system. collections. generic;  using  system.  using  system. web;  namespace  CDM. linqtoxml { public class   customer  { Public int  ID { set ;  Get ;}< span style =" color: blue "> Public String  name { set ;  Get ;}< span style =" color: Blue "> Public String  address { set ;  Get ;}< span style =" color: blue "> Public int  Age { set ;  Get ;}}

2. Add the gridview control on the default page. The Code is as follows:
 

 <  Form  ID  = "Form1"  Runat  = "Server"> <  Div  > <  ASP  :  Gridview  ID  = "Mygv"  Runat  = "Server"  Autogeneratecolumns = "False"  Datakeynames  = "ID"  Onrowcommand  = "Mygv_rowcommand"> <  Columns  > <  ASP  :  Commandfield  Causesvalidation  = "False"  Showselectbutton  = "True"  Buttontype  = "Image" Selectimageurl  = "~ /Right.gif "/> <  ASP  :  Boundfield  Datafield  = "ID"  Headertext  = "ID"/> <  ASP  :  Boundfield  Datafield  = "Name"  Headertext  = "Name"/> < ASP  :  Boundfield  Datafield  = "Address"  Headertext  = "Address"/> <  ASP  :  Boundfield  Datafield  = "Age"  Headertext  = "Age"/> </  Columns  > </  ASP :  Gridview  > </  Div  > </  Form  > 

Note that you have to write an event to get the primary key of the current row.

 
Onrowcommand= "Mygv_rowcommand"
 

 
3. The Code will assign values to the object class "customer". The Code is as follows:
 

 Protected void Page_load ( Object Sender, Eventargs E ){ List <Customer > List = New  List < Customer > (); List. Add ( New  Customer {Id = 1, name = "Caodaiming" , Address = "Sichuan" , Age = 23}); list. Add ( New  Customer {Id = 2, name = "Caodaiming" , Address ="Sichuan" , Age = 23}); list. Add ( New  Customer {Id = 4, name = "Caodaiming" , Address = "Sichuan" , Age = 23}); mygv. datasource = List; mygv. databind ();}

4. Add the primary key event code for the current row as follows:

Protected voidMygv_rowcommand (ObjectSender,GridviewcommandeventargsE ){ObjectS = mygv. datakeys [Int. Parse (E. commandargument. tostring ()]. value; response. Write (S. tostring ());}
