Understanding Commands in WPF: A Cleaner Alternative to Button Click Events

Many WPF developers start by using Button Click events for handling user actions. At first, this seems simple and straightforward. But very soon, the code-behind file becomes huge , and maintaining it turns into a challenge. One big problem arises: when the logic changes, the button does not enable or disable automatically , and testing button click logic becomes very difficult. So the big question is: Is there a better way to handle button actions in WPF? The answer is Commands . In this post, we’ll learn how to use Commands in WPF with a simple, practical example. We’ll cover: What a Command is How it works Why using Commands is better than Click events How buttons can automatically enable or disable based on conditions What is a Command in WPF?

What is namespace in c# ?


Namespaces in C# are used to organize classes.To access the class of a namespace, we need to use namespacename.classname. namespace is designed for providing a way to keep one set of names separate from another. The class names declared in one namespace does not conflict with the same class names declared in another. To define a namespace we need to use "namespace". eg.
  namespace NamespaceName
 { 
     class className
     {
     }
 }

 namespace WpfWorldNamespace
 { 
     class WpfWorld
     {
     }

 }
if we want to use WpfWorld class in another class then we have to add WpfWorldNamespace to that class by using Keyword.

 using WpfWorldNamespace;
 namespace ExNamespace
 { 
     class Ex
     {
       var objWpfWorld = new WpfWorld();
     }

 }
