Master DataContext and Binding in WPF

Before diving into WPF, there’s one crucial concept you need to understand: DataContext and Binding. Without it, WPF can feel confusing, no matter how much code you write. Many beginners often say: “ My binding is not working. ” The real reason behind this is simple—DataContext is not clear. If you want to work confidently with MVVM, Prism, or any professional WPF application, understanding DataContext and Binding is essential. In this post, we’ll break down these concepts in a simple and practical way, explain how they work together, and why they form the backbone of WPF development. What is DataContext? In simple terms, DataContext is the source of data for your UI controls. It tells WPF: “ From where should I get the data? ” The DataContext is usually the binding source object used for evaluating the binding path. Think of it like a shared office drive: All employees access data from the same drive location. Similarly, when you set a DataContext, all child controls automatically use...

Is it possible not to implement interface method in implementation class?

Yes, it is indeed possible to avoid implementing interface methods in the implementation class. To achieve this, you can declare the methods you don't wish to implement as abstract within the interface. By doing so, you'll need to mark the class as abstract as well. This allows you to provide the implementation of the method in a derived class of the abstract class. Let's take an example scenario using C#: interface ITest  {         void Sum();  } abstract class SumTest : ITest  {        public abstract void Sum();  } In this code, the SumTest don't have the implementation of the Sum() method. This approach can be useful when you require a method implementation but don't want to provide it immediately. By using the abstract modifier, you're indicating that derived classes should implement this method. This flexibility is particularly helpful when you want to delay the implementation until a more appropriate time. ...

What is Abstraction in C#?

The process of defining a class by providing the necessary and essential details of an object to the outside world and hiding the unnecessary things is called abstraction in C#. In C# we can hide the member of a class by using private access modifiers. Let us understand this with a car example. As we know a car is made of many things, such as the name of the car, the color of the car, gear, breaks, steering, silencer, diesel engine, the battery of the car, engine of the car, etc. Now you want to ride a car. So to ride a car you should know function of Gear,Break and Steering you no need to know engine of the car.so here in case of abstraction we can hide engine details so to do that make engine function private inside class and all require thing what we should know make it's function public.
