Delegates are fundamental to the .NET Framework (events and callbacks wouldn't work without them) and can be extremely powerful to the .NET Developer once they come to grasps with exactly what they are and how to use them. In this blog I will consider aspects of a real world situation in which delegates are useful, after which I will explain, in illustrative terms exactly what delegates are all about. You will see how delegates are an intrinsic part of the events structure in the .NET framework...

The ThreadPool.QueueUserWorkItem method lets me pass information to the delegate that will be executed on the worker thread. That's great, but I don't want to use a thread from the pool for this purpose as my scenario really requires a dedicated thread. Unfortunately, the ThreadStart delegate I use to start a new thread is parameterless. How do I pass data to a new thread?...

In the above case, suppose two thread subscribed to the same OperationComplete handler and one unsubscribed the event. In such scenario the OperationComplete event will become null and for the next thread due to the event is null it will not execute. This happens mainly in multithreaded applications but you can't guarantee for single threaded application too....

You are using the PropertyGrid control to allow the user to edit the properties of an object at run-time from the UI. This works great and is in fact very reliable since this is the same control used by Visual Studio to display the properties of controls. Now that you are letting the user update the object directly, you’d like to get a PropertyValueChanged event whenever the user changes a property, so you can respond to the user’s action. You’ll be able to do that by adding a PropertValueChange...

Event-driven programming is a computer programming paradigm in which the flow of the program is determined by user actions (mouse clicks, key presses), other hardware events, or messages from other programs[1]. The alternative is batch programming, where the programmer writes a fixed control sequence determining the actions of the program. In the Microsoft Windows environment, event-driven programs contain an event loop that is registered with the operating system. The operating system passes me...

This example shows how to add an event handler to an element by using code. If you want to add an event handler to a XAML element, and the markup page that contains the element has already been loaded, you must add the handler using code. Alternatively, if you are building up the element tree for an application entirely using code and not declaring any elements using XAML, you can call specific methods to add event handlers to the constructed element tree....

Dot Net Remoting is a simple programming model/framework which allows objects from different machines/processes/app-domains to communicate each other. It allows the flexibility of using different types of communication protocols (tcp, http etc..) and message formatters (binary, SOAP etc..). Communication among different app-domains is facilitated by Remoting objects. Remoting objects can be hosted using Managed Executables/IIS/.Net Component Services. It is also possible for .Net applications ru...

In this article we will deal with Delegates in C#. I tried my best to keep this article very simple so that people could understand the basics of delegates.

In simple words when you invoke something on Delegates it Delegates( means hand over) to some one. Delegates acts like a bridge between a person that is invoked and a person responding.

Perhaps you can recall from high-school days that sound travels with Particles. Sound emitted at Point A(Source) reaches Point B (Receiver) wit...

All of us have been exposed to event driven programming of some sort or the other. C# adds on value to the often mentioned world of event driven programming by adding support through events and delegates. This article is a part of a series that aims at understanding fully the way in which delegates and events operate. Part1 helps you understand the role of multicast delegates in the context of UI interaction. The emphasis of this article would be to identify what exactly happens when you add an ...

Events notify client objects of an action; for example, the controls in a GUI are event-driven. Windows applications are event-driven. An event is often a change of state: a change in the mouse position, a change in the mouse button position, a change of the keyboard state as a key is pressed, etc. Event references are defined using the delegate type....

This article aims to show you what goes on behind the "magic" that the compiler does when you declare a simple event member in a class. It is meant as a beginner article to answer a frequently-asked question, so please don't vote it down just because it is very basic. A pre-requisite to understanding how events work under the surface is to understand how multicast delegates work. A multicast delegate is a combined delegate that is made up of multiple single delegates joined together into a singl...

In many cases, developers have a demand to call methods testing some conditions before, like, if or switch statements. In most cases, developers call different methods on different conditions. And sometimes, developers need to call different methods either in loops or consequently. All cases mentioned above are covered by this article. Here, you can find several C# code examples that demonstrate how to solve such tasks in an efficient manner. Hope this article will be helpful....
