How to stop any user to delete an item from a sharepoint list?

Question

In SharePoint 2013, how can I stop users from deleting a item from one of many lists on many sites.

We can't change permissions level because it's a enterprise level product and dealing with permissions for such tasks would take ages and will create a lot of mess , I am thinking about using event receiver to stop user from deleting item but how ?

public override void ItemDeleting(SPItemEventProperties properties)
{
    //base.ItemDeleting(properties);
    properties. // how to cancel ??
}

Answer 1

properties.Status = SPEventReceiverStatus.CancelNoError; OR .CancelWithError

Answer 2

The following code snippet will prevent item deletion and also notify the user of what happened

public override void ItemDeleting(SPItemEventProperties properties)
{
    base.ItemDeleting(properties);
    properties.Status = SPEventReceiverStatus.CancelWithError;
    properties.ErrorMessage = "This item cannot be deleted; Contact your administrator";

}

The above snippet generates the following error when a user tries to delete an item in a list where the event receiver is active:

Answer 3

You can use below ItemDeleting method:

public override void ItemDeleting(SPItemEventProperties properties)
{
    properties.ErrorMessage = "Your Message goes here!";
    properties.Cancel = true;
}

UPDATE

As above method is deprecated you can use below method, using Status property.

SPEventPropertiesBase.Status property

public override void ItemDeleting(SPItemEventProperties properties) {
    properties.Status = SPEventReceiverStatus.CancelNoError;
}
