Data Binding Overview Microsoft Docs. Windows Presentation Foundation WPF data binding provides a simple and consistent way for applications to present and interact with data. Elements can be bound to data from a variety of data sources in the form of common language runtime CLR objects and XML. Content. Controls such as Button and Items. Controls such as List. Box and List. View have built in functionality to enable flexible styling of single data items or collections of data items. Sort, filter, and group views can be generated on top of the data. The data binding functionality in WPF has several advantages over traditional models, including a broad range of properties that inherently support data binding, flexible UI representation of data, and clean separation of business logic from UI. This topic first discusses concepts fundamental to WPF data binding and then goes into the usage of the Binding class and other features of data binding. What Is Data Binding Data binding is the process that establishes a connection between the application UI and business logic. If the binding has the correct settings and the data provides the proper notifications, then, when the data changes its value, the elements that are bound to the data reflect changes automatically. Data binding can also mean that if an outer representation of the data in an element changes, then the underlying data can be automatically updated to reflect the change. For example, if the user edits the value in a Text. Box element, the underlying data value is automatically updated to reflect that change. A typical use of data binding is to place server or local configuration data into forms or other UI controls. In WPF, this concept is expanded to include the binding of a broad range of properties to a variety of data sources. In WPF, dependency properties of elements can be bound to CLR objects including ADO. NET objects or objects associated with Web Services and Web properties and XML data. For an example of data binding, take a look at the following application UI from the Data Binding Demo The above is the UI of an application that displays a list of auction items. The application demonstrates the following features of data binding The content of the List. Box is bound to a collection of Auction. Item objects. An Auction. Item object has properties such as Description, Start. Price, Start. Date, Category, Special. Features, etc. The data Auction. Item objects displayed in the List. Box is templated so that the description and the current price are shown for each item. This is done using a Data. Template. In addition, the appearance of each item depends on the Special. Features value of the Auction. Item being displayed. If the Special. Features value of the Auction. Item is Color, the item has a blue border. If the value is Highlight, the item has an orange border and a star. The Data Templating section provides information about data templating. The user can group, filter, or sort the data using the Check. Boxes provided. In the image above, the Group by category and Sort by category and date Check. Boxes are selected. You may have noticed that the data is grouped based on the category of the product, and the category name is in alphabetical order. It is difficult to notice from the image but the items are also sorted by the start date within each category. This is done using a collection view. The Binding to Collections section discusses collection views. When the user selects an item, the Content. Control displays the details of the selected item. This is called the Master Detail scenario. The Master Detail Scenario section provides information about this type of binding scenario. The type of the Start. Date property is Date. Time, which returns a date that includes the time to the millisecond. In this application, a custom converter has been used so that a shorter date string is displayed. The Data Conversion section provides information about converters. When the user clicks the Add Product button, the following form comes up The user can edit the fields in the form, preview the product listing using the short preview and the more detailed preview panes, and then click submit to add the new product listing. Any existing grouping, filtering and sorting functionalities will apply to the new entry. In this particular case, the item entered in the above image will be displayed as the second item within the Computer category. Not shown in this image is the validation logic provided in the Start Date. Text. Box. If the user enters an invalid date invalid formatting or a past date, the user will be notified with a Tool. Tip and a red exclamation point next to the Text. Box. The Data Validation section discusses how to create validation logic. Before going into the different features of data binding outlined above, we will first discuss in the next section the fundamental concepts that are critical to understanding WPF data binding. Basic Data Binding Concepts Regardless of what element you are binding and the nature of your data source, each binding always follows the model illustrated by the following figure As illustrated by the above figure, data binding is essentially the bridge between your binding target and your binding source. The figure demonstrates the following fundamental WPF data binding concepts Typically, each binding has these four components a binding target object, a target property, a binding source, and a path to the value in the binding source to use. For example, if you want to bind the content of a Text. Box to the Name property of an Employee object, your target object is the Text. Box, the target property is the Text property, the value to use is Name, and the source object is the Employee object. The target property must be a dependency property. Most UIElement properties are dependency properties and most dependency properties, except read only ones, support data binding by default. Only Dependency. Object types can define dependency properties and all UIElements derive from Dependency. Object. Although not specified in the figure, it should be noted that the binding source object is not restricted to being a custom CLR object. WPF data binding supports data in the form of CLR objects and XML. To provide some examples, your binding source may be a UIElement, any list object, a CLR object that is associated with ADO. NET data or Web Services, or an Xml. Node that contains your XML data. For more information, see Binding Sources Overview. As you read through other software development kit SDK topics, it is important to remember that when you are establishing a binding, you are binding a binding target to a binding source. For example, if you are displaying some underlying XML data in a List. Box using data binding, you are binding your List. Box to the XML data. To establish a binding, you use the Binding object. The rest of this topic discusses many of the concepts associated with and some of the properties and usage of the Binding object. Direction of the Data Flow As mentioned previously and as indicated by the arrow in the figure above, the data flow of a binding can go from the binding target to the binding source for example, the source value changes when a user edits the value of a Text. Box andor from the binding source to the binding target for example, your Text. Box content gets updated with changes in the binding source if the binding source provides the proper notifications.
