Removing last item from ListView crashes app

Question

Hi all,

I am trying to remove items from a listview by manipulating the datasource and using listview.itemDataSource.remove(item.key)

This works for all items, until I hit the last one, which is when the app crashes with this:

Exception is about to be caught by JavaScript library code at line 10705, column 9 in ms-appx://microsoft.winjs.1.0/js/ui.js

0x800a138f - JavaScript runtime error: Unable to get property 'uniqueID' of undefined or null reference

Am I doing something wrong/ forgetting something here?

Thanks,

Answer 1

Are you using listview.forcelayout each time you remove an item from your listview.

I assume it is trying to delete an item from UI which is not existing in your listview and that seems to be the cause of this error.
