I would like to subscribe to whatever event is fired when my ASP.NET form is validated successfully.
Here is the scenario: On the click of a button on a payment form, I want to show a message 'processing,' however I only want to show this button when the for is validated succesfully.
I am using native ASP.NET form validation.
In a round-about way, you can if you override the Page_ClientValidate method as in:
var fn = Page_ClientValidate;
Page_ClientValidate = function(..) {
var result = fn(..);
if (result == true) {
//run code for success
}
}
I don't know why this was demoted but this approach is great because it works from all validation scenarios for customization (from buttons, WebForms_DoPostBackWithOptions client method, etc.).
HTH.
I don't think that the built in validators expose any such events. You could always use the CustomValidator and provide a OnClientValidate method that will combine the validation you're looking for as well as the UI changes you desire.
Call the following Javascript function whenever you want and pass the validation group name of your form to it..
function ValidateForm(ValidationGroupName)
{
var validated=Page_ClientValidate(ValidationGroupName);
if(validated)
{
//do the logic here
return true;
}
else
{
return false;
}
}
Hope this will help you....
I don't think it's going to be easy to do it your way but what you can do is the following:
<asp:Button onclientclick="if (Page_IsValid) return true; else {alert('Not Valid'); return false;}"/>
This will basically throw an error is validation is incorrect, otherwise it will continue.
