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 IXRColumnDefinition for each column in a grid. If you do not specify an IXRColumnDefinition, by default the grid will contain a single column with "star" sized width.

To set a group of column definition elements by using C++ code, add the IXRColumnDefinition to an IXRColumnDefinitionCollection. You can retrieve a pointer to this collection from the IXRGrid object, by calling IXRGrid::GetColumnDefinitions.

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

You can also define a column definition in Microsoft Silverlight 3. 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 ColumnDefinition Class on MSDN.
