Data Templating Overview Microsoft Docs. The WPF data templating model provides you with great flexibility to define the presentation of your data. WPF controls have built in functionality to support the customization of data presentation. This topic first demonstrates how to define a Data. Template and then introduces other data templating features, such as the selection of templates based on custom logic and the support for the display of hierarchical data. Prerequisites This topic focuses on data templating features and is not an introduction of data binding concepts.

Data. Template is about the presentation of data and is one of the many features provided by the WPF styling and templating model. For an introduction of the WPF styling and templating model, such as how to use a Style to set properties on controls, see the Styling and Templating topic. In addition, it is important to understand Resources, which are essentially what enable objects such as Style and Data. Template to be reusable.

Windows Presentation Foundation WPF ships with many of the common UI components that are used in almost every Windows application, such as Button, Label, TextBox. For more information on resources, see XAML Resources. Data Templating Basics To demonstrate why Data. Template is important, lets walk through a data binding example. In this example, we have a List. Box that is bound to a list of Task objects. Each Task object has a Task. Name string, a Description string, a Priority int, and a property of type Task.

Template Without a Data. Template, our List. Box currently looks like this Whats happening is that without any specific instructions, the List. Box by default calls To. String when trying to display the objects in the collection. Metro UI consists of a set of purposebuilt controls, custom Styles and resources for existing DotNetBar controls and common Microsoft controls, and an automatic. WPF. Therefore, if the Task object overrides the To. String method, then the List. Box displays the string representation of each source object in the underlying collection. For example, if the Task class overrides the To. String method this way, where name is the field for the Task. Name property public override string To. String. return name. To. String. Public Overrides Function To. String As String. Return name. To. String. Then the List. Box looks like the following However, that is limiting and inflexible. Also, if you are binding to XML data, you wouldnt be able to override To. String. Defining a Simple Data. Template The solution is to define a Data. Issuu is a digital publishing platform that makes it simple to publish magazines, catalogs, newspapers, books, and more online. Easily share your publications and get. Thanks to Pavlov Glazkov for explaining that the key and command bindings need to go at the ListBox level, rather than the item template level. A Grid contains a collection of UIElement objects, which are in the Children property. Columns and rows that are defined within a Grid can take advantage of Star. Template. One way to do that is to set the Item. Template property of the List. Box to a Data. Template. Top Psychology Programs In New York. What you specify in your Data. Template becomes the visual structure of your data object. WPF How to bind to data when the DataContext is not inherited. Setting the Template in a Style. In the previous example, we assigned a ControlTemplate to a ListBox by setting the Template property directly on the ListBox. The following Data. Template is fairly simple. We are giving instructions that each item appears as three Text. Block elements within a Stack. Panel. Each Text. Block element is bound to a property of the Task class. List. Box Width4. Margin1. 0.

The underlying data for the examples in this topic is a collection of CLR objects. If you are binding to XML data, the fundamental concepts are the same, but there is a slight syntactic difference. For example, instead of having PathTask. Name, you would set XPath to Task. Name if Task. Name is an attribute of your XML node. Now our List. Box looks like the following Creating the Data. Template as a Resource In the above example, we defined the Data. Template inline. It is more common to define it in the resources section so it can be a reusable object, as in the following example lt Window. Resources. lt Data. Template x Keymy. Task. Template. Stack. Panel. lt Text. Block TextBinding PathTask. Name. lt Text. Block TextBinding PathDescription. Text. Block TextBinding PathPriority. Stack. Panel. lt Data. Template. lt Window. Resources. Now you can use my. Task. Template as a resource, as in the following example lt List. Box Width4. 00 Margin1. Items. SourceBinding SourceStatic. Resource my. Todo. List. Item. TemplateStatic. Resource my. Task. Template. Because my. Task. Template is a resource, you can now use it on other controls that have a property that takes a Data. Template type. As shown above, for Items. Control objects, such as the List. Box, it is the Item. Template property. For Content. Control objects, it is the Content. Template property. The Data. Type Property The Data. Template class has a Data. Type property that is very similar to the Target. Type property of the Style class. Therefore, instead of specifying an x Key for the Data. Template in the above example, you can do the following lt Data. Template Data. Typex Type local Task. Stack. Panel. lt Text. Block TextBinding PathTask. Name. lt Text. Block TextBinding PathDescription. Text. Block TextBinding PathPriority. Stack. Panel. lt Data. Template. This Data. Template gets applied automatically to all Task objects. Note that in this case the x Key is set implicitly. Therefore, if you assign this Data. Template an x Key value, you are overriding the implicit x Key and the Data. Template would not be applied automatically. If you are binding a Content. Control to a collection of Task objects, the Content. Control does not use the above Data. Template automatically. This is because the binding on a Content. Control needs more information to distinguish whether you want to bind to an entire collection or the individual objects. If your Content. Control is tracking the selection of an Items. Control type, you can set the Path property of the Content. Control binding to to indicate that you are interested in the current item. For an example, see Bind to a Collection and Display Information Based on Selection. Otherwise, you need to specify the Data. Template explicitly by setting the Content. Template property. The Data. Type property is particularly useful when you have a Composite. Collection of different types of data objects. For an example, see Implement a Composite. Collection. Adding More to the Data. Template Currently the data appears with the necessary information, but theres definitely room for improvement. Lets improve on the presentation by adding a Border, a Grid, and some Text.
