Silverlight treeviewitem not updating

22-Jul-2017 00:07

I have a WPF Tree View that is bound to a hierarchy of a single type: Initially the Tree View binds as expected and correctly displays a multi-level hierarchy.

Also, when the membership of one of the Children collections is programmatically modified, the changes are correctly reflected in the Tree View.

Some of the feature implemented shadows my other reference but searching is exceptional good in this article.

Gets or sets a value indicating whether to clip the content of this element (or content coming from the child elements of this element) to fit into the size of the containing element.

This is a dependency property.(Inherited from UIElement.)Gets or sets the identifying name of the element.

The name provides a reference so that code-behind, such as event handler code, can refer to a markup element after it is constructed during processing by a XAML processor.(Inherited from Framework Element.)Positions child elements and determines a size for a UIElement.

A Command Binding enables command handling for this element, and declares the linkage between a command, its events, and the handlers attached by this element.(Inherited from UIElement.)Gets or sets a property that enables customization of appearance, effects, or other style characteristics that will apply to this element when it captures keyboard focus.(Inherited from Framework Element.)Gets or sets a value that declares whether this element can possibly be returned as a hit test result from some portion of its rendered content.The checkboxes will be in the correct state the first time any node is expanded, but afterwards they stop updating.I suspect this means the objects are not created/evaluated until they are actually due to be shown for the first time.The structure of data is Silverlight - Store Group has Observable Collection of Store Stores Through debugging I have noticed that there are no handlers attached to this.Property Changed, and am wondering if this is the problem?
