Is there a way for me to be notified when my ASP.NET form validation is successful so I can subscribe to that event?
Here's the situation: When a user clicks a button on a payment form, I want to display a message saying "processing," but only if the form has been successfully validated.
I am currently utilizing native ASP.NET form validation for this process.
If you want to customize validation scenarios, one way to achieve this is by overriding the Page_ClientValidate method like this:
var originalFunction = Page_ClientValidate;
Page_ClientValidate = function(..) {
var result = originalFunction(..);
if (result == true) {
//execute code for success
}
}
This approach allows for handling validations across various scenarios including button clicks and WebForms_DoPostBackWithOptions client method.
Hope this helps!
It seems that the default validators do not offer any events for this specific purpose. One workaround could be to utilize the CustomValidator instead, where you can define an OnClientValidate function to handle both the custom validation logic and any necessary UI updates.
Make sure to utilize the JavaScript function provided below at any desired point and input the validation group name of your form.
function CheckFormValidity(ValidationGroupName)
{
var validated=Page_ClientValidate(ValidationGroupName);
if(validated)
{
//enter your logic here
return true;
}
else
{
return false;
}
}
We hope this information proves beneficial for you...
It may not be a walk in the park to do it your way, but here's a suggestion:
<asp:Button onclientclick="if (Page_IsValid) return true; else {alert('Not Valid'); return false;}"/>
This approach will trigger an error if the validation is wrong, otherwise it will proceed.
