Ajax toolkit Control Learning Series (2) -- a test of confirmbuttonextender

After ajaxtoolkit is successfully installed, a simple example is provided to verify whether the installation is successful.

First read the results.

The confirmbuttonextender control is a pop-up window that controls other controls. It must be noted that confirmtext is displayed in the pop-up window. Targetcontrolid is used to specify the control. In this example, click the BTN button to trigger confirmbuttonextender.

  <  Form  ID  = "Form1"  Runat  = "Server"  >  
  < Div  >  
  <  ASP: scriptmanager  ID  = "SM"  Runat  = "Server"  >  
  </  ASP: scriptmanager  >  
  <  ASP: updatepanel ID  = "Updatepanel1"  Runat  = "Server"  >  
  <  Contenttemplate  >  
  <  ASP: button  ID  = "BTN"  Runat  = "Server"  Text = "OK"  Onclick  = "Btn_onclick"     />  
  <  ASP: Label  ID  = "LB2"  Runat  = "Server"  Text  = ""     > </  ASP: Label >  
  <  ASP: Label  ID  = "LB"  Runat  = "Server"  > </  ASP: Label  >  
  <  Ajax: confirmbuttonextender  Confirmtext  = "Hello World" Targetcontrolid  = "BTN"  ID  = "CBE"  Runat  = "Server"  >  
  </  Ajax: confirmbuttonextender  >  
  </  Contenttemplate  >  
  </ ASP: updatepanel  >  
  </  Div  >  
  </  Form  > 

Background Code :

 Code 

   Namespace Alex. ajaxlearning
{
  Public     Partial     Class  _ Default: system. Web. UI. Page
{
  Protected     Void  Page_load (  Object  Sender, eventargs E)
{

}
  Protected    Void  Btn_onclick (  Object  Sender, eventargs E)
{
  This  . Lb2.text  =     This  . CBE. targetcontrolid. tostring ();
  This  . Lb. Text  =     This . CBE. confirmtext. tostring ();
}
}
} 

There is nothing to say. In the pop-up window, the two labels read the name and displayed content of the control's target control.
