XamDataTree conditional ContentPresenter not updating when bound data changes
posted

Hello. I have a XamDataTree with a node layout that defines 3 types of content presenters, one with an Image and TextBlock, one with a text editor, and one with a date editor. 

For nodes that conditionally have the "TextBlockPresenter", when the "DisplayLabel" that the Text property is bound to changes, I am calling the underlying model object's PropertyChangedEvent but the text of the TextBlock is not updating in the tree to reflect the change. 

Is there something else I need to do to be able to change the model object and have the change reflected in the tree node?

    Hello Chris,

    I have been investigating into your requirement in this case, and I have put together a sample project based on the code that you have provided. In doing so, I cannot seem to reproduce the behavior where the “TextBlock” template is not updating? Perhaps the implementation of the INotifyPropertyChanged interface is incorrect in the case of your sample?

    I am attaching the sample project I used to test this and demonstrate it working correctly.

    Please let me know if you have any other questions or concerns on this matter.
