Thread Safety

Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

You typically use an IXRDataTemplate object to specify the visual representation of the content of a control, such as an IXRItemsControl. For example, if each item in a data collection includes a path to an image file and a string, you might display the string above an image control that displays the image. This is useful for controls that have multiple objects, such as an IXRItemsControl, and for objects that define how content is presented, such as an IXRContentPresenter. If the visual representation is defined in source XAML, IXRDataTemplate loads it and represents it as an object in the visual tree at run time.

When you create a class instance, use an IXRDataTemplatePtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.

In C++ code, you can retrieve the IXRDataTemplate for an IXRItemsControl by calling IXRItemsControl::GetItemTemplate. Then, you can set that template for another IXRItemsControl by passing it into IXRItemsControl::SetItemTemplate.

You must define this element in XAML using the DataTemplate element.
