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 can set an IXRRowDefinition for each row in a grid. If you do not specify an IXRRowDefintion, by default the grid will contain a single row with "star" sized height.

To set a group of row definition elements by using C++ code, add the IXRRowDefinition to an IXRRowDefinitionCollection. You can retrieve a pointer to this collection from the IXRGrid object, by calling IXRGrid::GetRowDefinitions.

The IXRRowDefinition class exposes only height properties. To set width properties in a grid object, create an instance of the IXRColumnDefinition class.

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

You can also define a row definition in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the RowDefinition Class on MSDN.
