Is it possible to disable the server side push button behavior using Javascript

Is it possible to disable the server side push button behavior using Javascript? Note. I do not want to disable the button, the user presses the button, but does not send / receive any value from the server.

scenario:

 <asp:Button ID="Button1" runat="server" Text="Submit"  onclick="Button1_Click"  OnClientClick="Check()" />

JavaScript:

function Check() 
{
  var res = confirm(" Are u sure whatYou have selected ")
  if (res) 
  {
    alert("yes");
  }
  else {
    //Here I need to disable the submit behavoiur                        
  }
 }
}
}

You need to make sure UseSubmitBehavior is set to false in the markup, then you need to make sure that you return false before the javascript postback is called.

Edit:

You must return the value of your function, and then in the retrun function true if you want to receive the postback, and return false if you do not.

<asp:Button ID="Button1" runat="server" Text="Submit"  onclick="Button1_Click"  
  OnClientClick="return Check();" UseSubmitBehavior="false" />

JavaScript:

function Check()
{
     return confirm(" Are u sure whatYou have selected ");
}

,

OnClientClick = "if (! Confirm ('are you sure?')) Return false;"

instead

1-OnClientClick = "return confirm (" are you sure? "))"

or

2-OnClientClick = "confirm (" are you sure? "))"

solved a problem

<asp:Button UseSubmitBehavior="false" OnClientClick="if (!confirm('are you sure?')) return false;" >
