Wpf mvvm listview not updating can carbon dating used diamonds
But WPF has a very special class Collection View Source which supports Filtering very effectively and in very easy way.First I have created a list of users in the constructor.I tried some possible solutions to this problem, but none of them worked. But when you update any property, WPF does not know about this because object does not changing.So maybe there is something generally wrong with my approach. Use Datatemplate or try call On Property Changed with empty string.Here is a possible code example: This might seem tedious at first, but it has helped me minimize and manage updates and bugs in Items Source quite nicely. Finally, I have found controlling the scroll View rather tedious when working with the List View Items Source, and have had better luck with simply using List View. Insert(...) method as when the Items Source is updated and a scrollview has been selected it has often thrown an Out Of Range exception. users Collection_Filter method will run for every binded item.
If you would like to stay with the INotified property changed interface you should set up the code as in the following documentation: https://msdn.microsoft.com/en-us/library/ms184414(v=vs.110).On Property Changed("My Items"); My Items[My Items. Has Information = true; // Note that "Selected Item" is persisted correctly, and always // points to the selected item that we want to update.Observable Collection only notifies the collection changes not the changes in each of the item.Everything works except for the fact that, if i'm updating the item description the List Box entry isn't updating.I read some articles about this, so i think it has something to do with Collection Changed isn't called. You does not use any datatemplate for listbox item, so WPF calls the To String() method for show item without DT.
