Hello,

I have a XamDataGrid that sets the background color depending on a status property within a model. The background is set correctly on start up but when I sort the columns using the built in sorter, the background color does not update. This causes some rows to have the wrong color and it does not correct itself until I scroll them out of view.

Here is my code below:

XAML View

<grids:XamDataGrid x:Name="dataGrid" AutoGenerateColumns="False" Grid.Row="1" Grid.RowSpan="11" RowHeight="40" SelectionMode="SingleRow" SelectedItemsChanged="dataGrid_SelectedItemsChanged" SortDescriptionsChanged="ApplySort">
    <grids:XamDataGrid.Columns>
        <grids:TextColumn PropertyPath="Col1" Width="*" DataBound="StylizeRowColor" HeaderText="Col 1" />
        <grids:TextColumn PropertyPath="Col2" Width="3*" DataBound="StylizeRowColor" LineBreakMode="WordWrap" IsFilteringEnabled="True"/>
        <grids:TextColumn PropertyPath="Col3" Width="*" DataBound="StylizeRowColor" IsFilteringEnabled="True"/>
        <grids:NumericColumn PropertyPath="Col4" Width="*" HorizontalAlignment="Center" DataBound="StylizeRowColor" IsFilteringEnabled="True"/>
    </grids:XamDataGrid.Columns>
</grids:XamDataGrid>

private List<DataModel> DataList;
private ColumnSortDescription DataSorter;
public SpreadsheetView()
{
    InitializeComponent();
    DataSorter = new ColumnSortDescription("Col1", Infragistics.Core.Controls.DataSource.ListSortDirection.Ascending);
    DataList = GetDataList();
    dataGrid.ItemsSource = DataList;
    dataGrid.SortDescriptions.Add(DataSorter);
    dataGrid.SortDescriptions.PropertyChanged += ApplySorting;
    dataGrid.ReactsToSortChanges = true;
}

public List<SlotMachine> GetDataList()
{
    return DataService.GetData();
}

private void StylizeRowColor(object sender, DataBindingEventArgs args)
{
    if (args.CellInfo != null)
    {
        var rowItem = args.CellInfo.RowItem;
        if (rowItem != null)
        {
            DataModel item = rowItem as DataModel;

            switch (item.Status)
            {
                case "InService":
                    break;
                case "OutOfService":
                    args.CellInfo.Background = new Infragistics.XamarinForms.SolidColorBrush(Color.Red);
                    break;
                default:
                    break;
            }
        }
    }
}

private void ApplySorting(object sender, PropertyChangedEventArgs e)
{
    if (dataGrid.ActualDataSource != null)
    {
        dataGrid.ActualDataSource.QueueAutoRefresh();
    }
}
