Hi Cristobal,

First of all, you must create a Custom GridViewCell, because our GridViewCell doesn't have id that can be used to bind with the cell background, so you must make a Custom one including the id inside the layout.

Please remember that you only need this code inside your view model to access data from model and repository or local List<> : this.SourceItems = this.Repository.GetAll().ToObservable();

Next to connect with the background color, there are however there are two method to access the value from the data

First Method is you can manipulate your model by adding this:

 public StyleAttributes ColorStyle        {            get            {                return new StyleAttributes(){
                    BackgroundColor=(this.Color == Red)?Color.FromArgb(0xff,0xff,0x00,0x00):Color.FromArgb(0xff,0xff,0xff,0xff)

                };
            }
        }

Note you can change Color.FromArgb with our premade color using for example: Colors.Red or Colors.Transparent, also remember to add 0x before hex code because it only accept byte

Then inside your binding provider you can add:

itemBinding.AddBinding("YourCellBackgroundID", BindableProperties.StyleAttributesProperty, new BindingDescription("ColorStyle"));

This could be done because when you can call List/Grid type you can also access your model from there

Another method you can use is converter:

Add this inside your binding provider:

itemBinding.AddBinding("YourCellBackgroundID", BindableProperties.StyleAttributesProperty, new BindingDescription("Color"){ Converter = new ColorConverter()});

Make new file named ColorConverter with class ColorConverter and insert this inside:

	public class ColorConverter: IValueConverter
	{
		#region IValueConverter implementation

		public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
		{
			if (value is String)
			{
				int CatColor = (String)value;

                if (CatColor == "Red")
                {
                    StyleAttributes style = new StyleAttributes();

                    style.BackgroundColor = Colors.Red;
                    return style;
                }
                else 
                {
                    StyleAttributes style = new StyleAttributes();

                    style.BackgroundColor = Colors.White;
                    return style;
                }
			}

			return null;
		}

		public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
		{
			throw new System.NotImplementedException();
		}

		#endregion
	}

Connect your binding provider with this converter

So in conclusion, i think the second method is more cleaner and doesn't manipulate the model too much... The only file you actually need to changes is just the Layout and Binding Provider (also model or converter)

You can also see this kind of implementation in our samples: http://git.intersoftpt.com/projects/CROS/repos/samples/browse/MyInventory

Hope that helps :)
