Hi
you can use jquery ajax to send email like for example
when you click on button to send email ,you have to call jquery ajax function
$("#btnSendEmai;").click(function(){
// Show message box
$('#dvMessage').show();
// Call SendEmail method
$.ajax({
url:'Default.aspx/SendEmail'
type:'Get'
datatype:'json'
async:false,
cache:false,
success:function(data){
// Hide message box on success
$('#dvMessage').hide();
},
error:function(msg){
}
});
});
