A problem with ContentTemplateSelector

[M]

Hi there,
I have bound the ItemsSource property of RadTileView to an ObservableCollection containing items with INotifyPropertyChanged interface implementation, and also I am using a ContentTemplateSelector that determines the template for the content of TileViewItems based on a property of the corresponding item named "Template".
The first time the RadTileView loads, it calls the template selector and sets the templates correctly, but if I change the "Template" property of any item in items source bound collection, the RadTileView does not call the template selector to determine the appropriate template again. It needs to set the ItemsSource of the RadTileView again to reflect the changes.
Is ther any solution to avoid setting the ItemsSource property every time I change the "Template" property of bound items?
Thanks

Hi M,
The problem in your case is that the ContentTemplateSelector is called only when the containers are generated (this is the default behavior of all selectors) and that's why it's not triggered on property change. If you want to be able to change the ContentTemplate runtime you'll have to bind the ContentTemplate property of the RadTileViewItem to the Template property in your business object (you'll have to use a converter).
I've attached a sample project so could you please examine it and if you have further questions feel free to ask.
