Changes

Because certain property collections are Lazy-loaded as described above, it may be the case that bindings to these properties appear null in certain circumstances, especially if the collection is loaded after the page is rendered, such as through a command or behavior. To troubleshoot this issue, you can ensure that the property collection is accessed during rendertime rather than runtime (simply put, while the page is being constructed rather than during normal use) by applying the same binding to, for example, a Label. This measure should still work if the Label is hidden from view using a visibility binding.

=== Editing Properties ===

* The [[XAML_Tips#SetPropertyValueCommand|Set Property Value Command]] sets a named property to a specific or calculated (such as through an [[EvalExpression]]) value.

== Commands ==

* ChildMetaDefUid: The Guid of the child meta definition to be used for creating the captured media document. If unspecified, the client will simply pick the first child meta definition that is of media type and is allowed under the current context/parent object.

== Object Filtering ==

{{Attention|While any of the above approaches can be used, it is never recommended to mix approaches, as this causes multiple rounds of filtering per keystroke that will noticeably impact performance, especially when many objects and filters are involved!}}

== Miscellaneous ==
