c# - Update one List<T> from another List<T> when data changes -

I have compiled a list box with observablecollection and selected items in my ViewModel.

XAML:

  & lt; List Box Itemsource = "{Binding Category}" selectedEystem = "{Binding Selected Category, Mode = Two}" / & gt;  

See # Model:

  Private listing & lt; Category & gt; _CategoryList = new list & lt; Category & gt; (); Private Category _SelectedCategory = New Category (); Public listing & lt; Category & gt; CategoryLst {get {return _CategoryList; } Set {setpropert (ref_categoryList, value); }} Public category selected category ({return _SelectedCategory;} set {setpropert (re-selected category, value);}}  

When I get a new list of data, It needs to be updated so that it is displayed evenly on the UI. Currently I am just specifying new data in the list and it updates the entire list on YouTube because on-noiteepporpettppt Changed Changes:

C # View Models

  CategoryLst = Updated Category Category;  

The cause of a flicker on the UI is because the selected item is bound to the UI. How can I update only those elements that are updated in the list without flicker due to the completion in the list?

combo box

to observation , while your view model shows you that in fact a list & lt; T & gt; . Regardless of this, you can make the archive playable by read-only and update categories on a single item-per-item basis. To work for this, you will definitely need to co-relate some updated old items of a CDE:

  // When updates are made, calls are made. .. Private Zero OnCategoryListUpdated () {Foreign currency (updated category category updated category) {Oncabes upgrade (updated category); }} Private Zero OnCategoryUpdated (Category Renewed Category) {var oldCategoryInList = CategoryList.SingleOrDefault (c => c.id == updatedCategory.Id); If (old countries list! = Null) {oldCategoryInList.PropertyA = updatedCategory.PropertyA; If categories like etc. can also be added or removed, then I suggest that you actually have a  ObservableCollecton & lt; T & gt; Use  so that your  combo box  will automatically update as needed, and you also need to make sure that your  SelectedCategory  remains in the updated archive (or Reset to  Blank ).
