Hi
I am trying to sort a Int32 column and it fails if any cell in the column is changed (Same for Group Panel). If I sort the column without cell changes no problem. I tried both creating the columns in xaml and in code with not difference. Also i am binding to an array of object. I also tried both Array and List. Also, the columns that are String sort properly when a cell is changed in the column. Am i missing something?
The code is as follows.
1. Create data class
2. View Model class
3. Main Page code behind
4. Xaml
Thanks
Rich
