Event binding of controls in repeater, internal template Column

 

The general method is to use the itemcommand event of repeat (DataGrid, datalist, and gridview are the same), as shown in

// . Aspx
< ASP: repeater ID =   " Repeater1 " Runat =   " Server " Onitemcommand =   " Repeaterpolicitemcommand " >  
< Itemtemplate >  
< ASP: button ID =   " BTN " Commandname =   " Sayhello " Runat =   " Server " Text =   " Sayhello " />  
</ Itemtemplate >  
</ ASP: Repeater >  

// . Aspx. CS
Protected Void Repeaterincluitemcommand ( Object Source, repeatercommandeventargs E)
{
Switch (E. commandname ){
Case " Sayhello " :
Response. Write (E. Item. itemindex );
Response. Write (E. commandargument ); // Custom parameter information
Break ;
}
}

3.
Directly set the button click event, of course, to processProgramYou need some skills to obtain other information, such:

// . Aspx
< ASP: repeater ID =   " Repeater2 " Runat =   " Server " Onitemcommand =   " Repeaterpolicitemcommand " >  
< Itemtemplate >  
< ASP: button ID =   " BTN " Runat =   " Server " Commandargument =   ' <% # Eval ("somefieldname") %> ' Text =   " Sayhello " Onclick =   " Btninrepeat2_click " />  
< Input ID =   " Btn2 " Runat =   " Server " Runat =   " Server " Value =   " Sayhello " Onclick =   " Btn2inrepeat2_click " />  
</ Itemtemplate >  
</ ASP: Repeater >  

// . Aspx. CS
Protected Void Btninrepeat2_click ( Object Sender, eventargs E)
{
// Button that triggers the event
Button BTN = Sender As Button;
// Row of Button
Repeateritem = BTN. namingcontainer As Repeateritem;
}

Protected Void Btn2inrepeat2_click ( Object Sender, eventargs E)
{
// Button that triggers the event
Htmlbutton BTN = Sender As Htmlbutton;
// Row of Button
Repeateritem = BTN. namingcontainer As Repeateritem;
}

For buttons, we recommend that you use the webcontrol button instead of runat.=Serer input,
You can see that the button has commandname and commandarguments.

Hope helpful!

1. HTML Web controls is not recommended
2. If you place a button in itemtemplate in repeater, you can use the itemcommand event to process the event. You do not need to register the event yourself.
