Changing card border

Hi Syncfusion Team, 

Last night I was working with the KanbanBoard and ran into an issue. So, I'm wanting to change the border color of the card depending on what the indicator pallete property is (which I cannot find with how I tried), but I did set it up so that I could loop through each column and then loop through each card in that column. I then wanted to set the card style to a RevealBorderBrush of a color according to the indicator pallette. 

So, for instance. When my program starts to run, kanbanControl.ItemsSource = DataAccess.GetData() is called under the MainPage constructor (for MainPage.xaml), and when I run the debugger and check, the items are in the items source. The code from the snippet below after GetData() runs, but the "Cards" property returns empty, and ItemsSource returns empty. 

1. public MainPage()
2.         {
3.             this.InitializeComponent();
4.             kanbanControl.ItemsSource = DataAccess.GetData(); // Get data from database
5.  
6.             // Add reveal focus to Kanban Card Items
7.             // Set card items background color according to priority color
8.             var brush = new RevealBorderBrush();
9.             KanbanCardStyle kanbanCardStyle = new KanbanCardStyle();
10.  
11.             // Test to turn border of card to what inidicator color pallette color is
12.             foreach (var col in kanbanControl.Columns)
13.             {
14.                 foreach (var model in col.ItemsSource as ObservableCollection<KanbanModel>)
15.                 {
16.                     // Model is empty?
17.                }
18.                 foreach (var card in col.Cards) // Nothing is in col.Cards apparently
19.                 {
20.                     //brush.Color = Colors.Red;
21.                     //brush.FallbackColor = Colors.Purple;
22.                    
23.                     //brush.Opacity = 0.8;
24.                     //card.BorderBrush = brush;
25.                     card.Background = new SolidColorBrush(Colors.Blue); // TEST: DOES NOT WORK
26.                    
27.                 }
28.             }
29.  
30.             brush.Color = Color.FromArgb(255, 0, 39, 76);
31.             brush.FallbackColor = Colors.Gray;
32.             brush.Opacity = 0.8;
33.             kanbanCardStyle.CornerRadius = new CornerRadius(10.0);
34.             kanbanCardStyle.BorderBrush = brush;
35.             kanbanCardStyle.BorderThickness = new Thickness(3.0);
36.             kanbanControl.CardStyle = kanbanCardStyle;
37.         }

BUT, if I set the background color on kanbanCardStyle and set that to the CardStyle on kanbanControl, it changes the background color...? So it seems like the items just returns 0? 

Thanks for your time!

That works perfectly!!

Thank you very much :)
