SfListView with a SortDescriptor doesn't always apply

[Thomas]

Hello,

I use a SfListView with a SortDescriptor, with a custom Comparer.
It works fine at first look (sorting work when adding a new object for instance), but sometimes when I modify some collection's object's properties which affect sorting, the sorting is forgot and the list shows the real collection order (which is not sorted), without even calling the Comparer function. If a restart the app or add a new object to the collection, the sort work great again.

How can I fix that please ?

Thanks

Hi Thomas,  

  

We have checked the reported query from our end.We would like to let you know that you can achieve your requirement by defining the property LiveDataUpdateMode to AllowDataShaping as like below example. If apply sorting, the updated item will sorted and also it will be applicable for grouping and filtering.   

  

Code Example[C#]:  

public GroupingPage()  

{  

   InitializeComponent();  

   listView.DataSource.LiveDataUpdateMode = LiveDataUpdateMode.AllowDataShaping;  

}  

  

Also, We have prepared a sample to achieve your requirement for your reference and you can download it from below link.
