ASP.NET MVC 3: Configuring unobtrusive validation

ASP.NET MVC 3 ofeers client side validation through the unobtrusive javascript and jQuery validation plugins. Most of the time the default behavior is fine, but what if you want to tweak the validation configuration?
Only validate the form fields when the form is submitted:
$(function() {
 var validationSettings = $.data($('#formToValidateId').get(0), 'validator').settings;
 validationSettings.onkeyup = false;
 validationSettings.onfocusout = false;
});

As you can see, it’s possible to change some settings through the  validator settings object. By setting  the onkeyup and onfocusout properties to false, the validation on blur and key up will be disabled.
Disable the validation on input fields with class ignore.
$(function() {
 var validationSettings = $.data($('#formToValidateId').get(0), 'validator').settings;
 validationSettings.ignore = '.ignore';
});


Setting the ignore property of validator settings object to .ignore will tell the jQuery validation plugin to ignore all input elements with class ignore during validation. 


Of course there are a lot more options you can configure. For a complete list of jQuery validation options have a look here.

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
