What is WPF?

WPF is a framework for building Windows applications that allow users lớn develop rich user interfaces having 3D animations and rich colors with less code complexity. It is a vector-based rendering engine that uses hardware acceleration of modern graphics cards, which makes the Ul faster & highly scalable. WPF stands for Windows Presentation Foundation.

WPF can be considered as an evolution over WinForms. It produces easy khổng lồ operate graphical display system for Windows. It offers easy separation between UI và business xúc tích. WPF applications can be deployed in your system as a standalone desktop program or hosted as an embedded object in a website. In this C# WPF tutorial for beginners, you will learn WPF basics like:

Why WPF?

There are many reasons for using WPF platsize some prominent ones are-
An ideal platform to lớn use if you require khổng lồ giảm giá with various media types WPF allows you to create a skinned user interface. It also helps you when you need khổng lồ load portion of the UI or want to lớn bind XML data Resolution independence, so application developed using WMF can be run on mobile devices or a 20-inch monitor WPF builds on DirectX instead of WinAPI. It offers the client computer"s graphics system. Therefore, offering greater graphic rendering power Supports a flow document Mã Sản Phẩm which enables "desktop publishing" quality of the layout Appearance & behavior are loosely coupled. This allows designers and developers lớn work on two separate models In WMF framework you can graphically thiết kế tools on simple XML documents instead of parsing code Allows you to lớn use hardware acceleration for drawing the GUI, for better performance

History of WPF

Windows 1.0 was the first GUI environment from Microsoft. It is working as a layer on top of DOS, relying on the GDI và USER systems for graphic và user interface. DirectX was introduced in the year 1995, as a high-performance graphics system. It was aimed at games & other graphics related environments. Over the years there are many versions released with Directx9 that provides a library to lớn use with mange.Net code. WPF version Release Year .Net Version Visual Studio Version Features
3.0 2006 3.0 N/A Initial Release. However, WPF development can be done with VS 2005.
3.5 2007 3.5 VS 2008 Modification & improvements in: Application mã sản phẩm, binding, controls, documents, annotations, and 3-D Ul elements.
3.5 SP1 2008 3.5 SP1 N/A Native splash screen tư vấn. New website browser control, DirectX pixel shader support.
4.0 2010 4.0 VS 2010 New controls: Calendar. DataGrid, DatePicker. Multi-Touch and Manipulation

Features of WPF

Features of WPF Features of WPF Documents và Printing Security, Accessibility & Localization Offers Interoperability with Windows Forms controls Direct3D is used in graphical applications where performance is important Uses the Clip thẻ hardware for rendering Vector-based graphics allows you to lớn scale your application without loss of quality WPF supports floating-point logical px system & 32-bit ARGB color Redefine Styles and Control Templates Building international fonts from composite fonts WPF text rendering helps you to takes advantage of ClearType technology Allows you to use the caching technique of pre-rendered text in the video clip memory Resource-based Approach for every control Presentation timers are initialized & managed by WPF The relationship between Clip and animation is also supported In WPF a style is a phối of properties which should be applied lớn nội dung used for visual rendering Templates in WPF helps you to lớn change the Ul of your document Commands are more abstract và loosely- coupled version of events WPF tư vấn for commands reduces the amount of code we need khổng lồ write Next in this WPF C# tutorial, we will learn about WPF core types and Infrastructure.

WPF Core Types & Infrastructures

Classes in WPF are divided inlớn four different types: UIElement FrameworkElement ContentElement FrameworkContentElementThese classes, known as base element classes. It provides the foundation for a mã sản phẩm of composing user interfaces. WPF user interfaces are composed of elements which are assembled in a tree hierarchy. It is called the element tree. The element tree is an intuitive way to layout user interface. It is a structure which allows you khổng lồ get the feature of powerful UI services.

XAML

Extensible Application Markup Language which is called "XAML", or "zammel" is a declarative sầu way to lớn define user interfaces. Here is the XAML definition of a simple button: Say Hello giamcanherbalthin.comAdvantage of using XAML language: XAML separating front-kết thúc appearance from back-over xúc tích XAML is the easiest method lớn represent user interfaces XAML is work effectively with tools

Controls

WPF framework supports many useful controls like: Editing controls lượt thích TextBox, CheckBox, RadioButton List controls such as ListBox, ListView, TreeView User information such as Label, WPF ProgressBar, ToolTip Action such as Menu, Button, and ToolBar Appearances such as Border, WPF Image, & Viewbox Comtháng dialog boxes such as OpenFileDialog and PrintDialog. Containers such as TabContro, ScrollBar, and GroupBox Layouts like DocPanel, StackPanel, and Grid Navigation such as Frame và Hyperlinks The appearance of controls can be customized with styles và templates without programming. You can also create a custom control by deriving a new class from an appropriate base class.

Appearance

WPF provides a feature for customizing the appearance of your application. It allows you to phối objects and value for things lượt thích fonts, backgrounds, etc. The styles feature allows you to standardize on a specific look for the entire product. It allows you to replace the default appearance while retaining its mặc định behavior. Data template allows you lớn control the mặc định visualization of the bound data. With the help of themes, you can easily visualize styles from the operating system.

Layout và Panels

Layout helps you in proper positioning và sizing control. It is part of the process of composing the presentation for the user. The WPF framework eases the layout process and offers better adaptability of the UI appearance. The layout infrastructure is offered by various classes are 1) StackPanel 2)DockPanel 3) WrapPanel 4) Grid and 5) Canvas

Graphics

WPF provides an improved graphics system lượt thích WPF uses device-independent units, enabling resolution and device independence. Therefore, each pixel, which is device-independent, automatically scales with the dots-per-inch setting system WPF uses double instead of float và supports a wider array of colors The WPF graphics engine is designed in such a way that it can take advantage of graphics hardware when available

Documents & Printing

WPF framework offers three types of documents: Fixed documents: This type of document supports WYSIWYG presentation.Flow documents: Allows you lớn adjust & reflow nội dung based on run-time variables lượt thích window kích cỡ và device resolution.XPS documents: It is a paginated representation of electronic paper in an XML- based format. XPS is an open source và cross-platform document format.WPF enables better control over the print system. It includes remote printing và queues. Moreover, XPS documents can be printed directly without converting it inkhổng lồ a print format.

WPF Architecture

WPF is a part of the .NET framework. It contains both managed và unmanaged code. The important components of WPF architecture are explained in the below-given figure: WPF Architecture WPF Architecture The most important components of WPF architecture in C# are ? PresentationFramework: Helps you lớn create top-level elements lượt thích Controls, styles, layout, windows, etc. PresentationCore: It holds base types such as UIElement, Visual from all Controls and shapes are Derived in PresentationFramework.dll. Milcore: Milcore is a part of the unmanaged code which offers tight integration with DirectX. DirectX: It is the low-cấp độ API which allows rendering graphics of WPF. DirectX talks interact with drivers and render the nội dung. User32: It is the is a core API which is widely used by many programs. It manages memory & process separation. User32 helps you to lớn decides which element will be placed where on the screen. Kernel: Input originates as a signal on a kernel mode device driver và gets routed to the correct process và by connecting with Windows kernel và User32.
