Modifying an ObservableCollection declared as a resource at runtime?
Got it! A resources value can be set through Application.Current. Resourceskey So in my example, should anyone run into this problem I do something like MyObservableCollection coll1 = Application.
FindResource("resourceName") as MyObservableCollection foreach(Item I in coll1) { if(somecondition){i. SomeProperty == someValue;} } //coll2 does NOT reflect the above change! MyObservableCollection coll2 = Application.
FindResource("resourceName") as MyObservableCollection; Application.Current. Resources"resourceName" = coll1; //coll3 DOES reflect the above change MyObservableCollection coll3 = Application. FindResource("resourceName") as MyObservableCollection.

FindResource("resourceName") as MyObservableCollection.
I have a bunch of ObservableCollections which are populated from a database. There's agood chance that during the application lifetime these collections will grow and I need them to be updated every 30 seconds or so. I declare the collections as resources in merged dictionaries in App.xaml.
I can fetch these collections fine by using the Application.FindResource() method but any changes I make to the resulting collection are not reflected when I call FindResource again. Maybe I'm naive to think this would be the case. Am I right or wrong?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
