Wpf C Observablecollection Not Updating Gui Stack Overflow Wpf provides the observablecollection class, which is a built in implementation of a data collection that implements the inotifycollectionchanged interface. the next part is that an observablecollection will only notify on changes to the collection itself (add remove). My delete and add methods work fine, the update is calling the httpput and changing the data but i cant get the wpf form to update the same way i have been updating with add and delete. my class is implementing inotifypropertychanged and i have the onpropertychanged method.

C Datagrid Not Updating With Observablecollection Stack Overflow I use a observablecollection in my wpf application but unfortunately the items are not updating until i restart my wpf application. how can i solve that? here is my observablecollection : private observablecollection devices { get; set; } public observablecollection devices { get { return devices; } set { devices = value;.

I have a datagrid on two levels, i manage to update my ui for the first datagrid, but i have a problem for the second one. although i can update the properties in the grid, when i want to remove add a new row (with an observablecollection), the ui is not updating while the collection is modified. The reason the propertychanged event exists is to tell wpf when a property has changed so it can update. you're setting a field without raising the event, so wpf is clueless. I have an observablecollection bound to a view. adding to the collection from another viewmodel doesn't change the view after addition. closing the app and reopening does, though. here's the view:
