Implement code that prevents multiple page submissions in ASP. NET

The Code provided here is used to disable all the buttons on the asp.net page after a Button is clicked, thus preventing multiple submissions due to submission delay. Based on the previous onceclickbutton script.

 
 

  
  
// Code preventing multiple page submissions in ASP. NET: javascript
  
  
< Script Language="Javascript"> 
  
  
 <! --
  
  

  
  
Function disableOtherSubmit ()
  
  
{VarObj=Event. SrcElement;
  
  
VarObjs=Document. GetElementsByTagName ('input ');
  
  
For (varI=0; I< Objs. length; I ++)
  
  
{
  
  
If (objs [I]. type. toLowerCase () = 'submit ')
  
  
{
  
  
Objs [I]. Disabled=True;
  
  
}
  
  
}}
  
  

  
  
//--> 
  
  
 </Script>
 
 

 
 

  
  
//Code Used in ASP. NET to prevent multiple page submissions: asp.net
  
  
Public ClassPreventMultiClick: System. Web. UI. Page
  
  
{
  
  
 ProtectedSystem. Web. UI. WebControls. Button Button1;
  
  
 ProtectedSystem. Web. UI. WebControls. Button Button2;
  
  
 ProtectedSystem. Web. UI. WebControls. LinkButton LinkButton1;
  
  
 ProtectedSystem. Web. UI. WebControls. Button Button3;
  
  

  
  
 Private VoidPage_Load (ObjectSender, System. EventArgs e)
  
  
{
  
  
 This. GetPostBackEventReference (This. Button3 );// Ensure that _ doPostBack (eventTarget, eventArgument) is correctly registered 
  
  
 If(! IsPostBack)
  
  
{
  
  
System. Text. StringBuilder sb =NewSystem. Text. StringBuilder ();
  
  
Sb. Append ("If (typeof (Page_ClientValidate) = 'function') {if (Page_ClientValidate () = false) {return false ;}}");// Verify the execution of the Function 
  
  
Sb. Append ("If (window. confirm ('are you sure? ') = False) return false ;");// Customize the client script 
  
  
Sb. Append ("DisableOtherSubmit ();");// Disable all submit buttons 
  
  
Sb. Append (This. GetPostBackEventReference (This. Button3 ));// Submit with _ doPostBack to ensure that the click Event of the button is executed on the server side. 
  
  
Sb. Append (";");
  
  
Button3.Attributes. Add ("Onclick", Sb. ToString ());
  
  
}
  
  
}
  
  
# Region Web Form Designer generated code
  
  
 Override Protected VoidOnInit (EventArgs e)
  
  
{
  
  
 // 
  
  
 // CODEGEN: This call is required by the ASP. NET Web Form Designer. 
  
  
 // 
  
  
InitializeComponent ();
  
  
 Base. OnInit (e );
  
  
}
  
  

  
  
 /// <Summary> 
  
  
 /// Required method for Designer support-do not modify 
  
  
 /// The contents of this method with the code editor. 
  
  
 /// </Summary> 
  
  
 Private VoidInitializeComponent ()
  
  
{
  
  
 This. Button3.Click + =NewSystem. EventHandler (This. Button3_Click );
  
  
 This. Load + =NewSystem. EventHandler (This. Page_Load );
  
  
}
  
  
# Endregion
  
  
 Private VoidButton3_Click (ObjectSender, System. EventArgs e)
  
  
{
  
  
System. Threading. Thread. Sleep (3000 );
  
  
Response. Write ("Hello world! ");
  
  
}
  
  
}
 
 

Here, only disable all the submit buttons. I think other submit controls can also be disable in a similar way.
