Refer to the attached reproducible.

1. Run app and apply a filter: "Contains 0"

2. Notice #40 is in the correct location, between #30 and #50

3. Press the button on the bottom of the page to go BlankPage and then navigate back.

4. Observe #40 is now at the end of the rows even though the filter is clearly applied.

Look in MainPageViewModel.cs lines 42 to 49. When the navigation back occurs, this code is executed.  I can reproduce the problem with both Replace and Add+Remove operations.

public override void OnNavigatedTo(INavigationParameters parameters)
{
    base.OnNavigatedTo(parameters);

    if (!parameters.ContainsKey("from"))
    {
        var items = new ObservableCollection<MyModel>();
        for (var i = 1; i <= 100; i++)
            items.Add(new MyModel { Number = i.ToString() });
        Items = items;
    }
    else
    {
        var item = Items[39];

        // Bug Test #1 - using ObservableCollection Reset
        Items[39] = item;

        // Bug Test #2 - using ObservableCollection Remove & Add
        //Items.RemoveAt(39);
        //Items.Insert(39, item);
    }
}

The DataGrid  documentation is missing a Styling article. It should cover how to use the following:

- DataGridBorderStyle (and how it's used for the RowBackground styles and SelectedStyle
- DataGridTextCellStyle (especially how as the CellContentStyle it lets you set the SelectedTextColor)
- DataGridLoadOnDemandStyle
- DataGridColumnHeaderStyle
- DataGridGroupHeaderStyle
- DataGridHeaderStyle

I think the Styling section might need it's own node with a few articles as the information would be too large for one article

When defining TextColumns with a CellStyleSelector, it works correctly the first time the DataGrid is bound to the ItemsSource.

If you then update the bound collection (which has PropChanged wired up), the CellStyleSelector's SelectStyle method is properly executed, but the DatasGrid doesn't use the returned DataGridBorderStyle.

iOS - Works as expected
UWP - Background color doesn't update
Android - Background color doesn't update
