style trigger

[Robert]

Hi,

I am still rather new to WPF in general but trying to come up to speed.  I am using RadTileList in an app.  I am using it for "recent items" in an application.  Those items point to different modules.  These modules are color coded.  So when the tile renders, I want to select a particular background color of the tile, e.g. Employees = green, Crm = blue, etc.

I am using ItemsSource to a view model property

Here is the main radTileList

 <telerik:RadTileList
            CanUserSelect="False"
            x:Name="HomeTileList"
            ItemsSource="{Binding Path=RecentItems}"
            GroupTemplate="{StaticResource GroupTemplate}"
            Margin="5,5,0,0"
            TileReorderMode="None"
            ScrollViewer.HorizontalScrollBarVisibility="Auto">
....

I put in this style
  <Style TargetType="telerik:Tile" >
                <Setter Property="TileType" Value="Single" />
                <Setter Property="Group" Value="{StaticResource tgRecent}" />
                <!--<Setter Property="Background" Value="{Binding ModuleCode, Converter={StaticResource StringToTileBackgroundConverter}}"/>-->
                <Setter Property="Background" Value="{StaticResource ModuleSolicitation}" />
                <Setter Property="Background" Value="Black" />
                <Style.Triggers>
                    <DataTrigger Binding="{Binding EntityId}" Value="1">
                        <Setter Property="Background" Value="Red" />
                    </DataTrigger>
                </Style.Triggers>
            </Style>


I have tried a value converter and a dataTrigger.  In the current form, the app picks up the "black" background, but it does not seem to be checking against the EntityId field to render a Red tile.

Note: I eventually want to tied the background color based on the ModuleCode which is an enum.  But I am doing EntityId for testing so that that I can have 1=1 so to speak while I figure this out.

this is "RecentItems" as the collection from the dataContext of the view.

 public ObservableCollection<RecentItemViewModel> RecentItems { get; private set; }

and here is the class

 public class RecentItemViewModel : ViewModelBase
    {
        private int _entityId;
        private string _entityName;
        private Enums.Module _moduleCode;

        public int EntityId
        {
            get { return _entityId; }
            set
            {
                if ((_entityId != value))
                {
                    _entityId = value;
                    RaisePropertyChanged("EntityId");
                }
            }
        }

        public string EntityName
        {
            get { return _entityName; }
            set
            {
                if ((_entityName != value))
                {
                    _entityName = value;
                    RaisePropertyChanged("EntityName");
                }
            }
        }

        public Enums.Module ModuleCode
        {
            get { return _moduleCode; }
            set
            {
                if ((_moduleCode != value))
                {
                    _moduleCode = value;
                    RaisePropertyChanged("ModuleCode");
                }
            }
        }
    }


any ideas?

Hello Robert,

Actually, it turns out to be a bug in tile list. I have already resolved it and the fix will be available in the internal build coming on next Monday.
I have updated your telerik points.

Hello Robert,

As it turns out, we will need a bit more time for investigating the case. I will write you back as soon as I could provide more information on the topic. In the mean time you can try something as follows:

private void HomeTileList_AutoGeneratingTile(object sender, AutoGeneratingTileEventArgs e)
        {
            e.Tile.DataContext = e.Tile.Content;
        }

Thank you for your patience.

Thanks.  That "fixes" my problem.  Although, I was originally trying to set background through a converter.  I still tried that one, but it did not seem to work.  Stacking up my style triggers did with the event above did.

I would like to use a converter (less View clutter) becausethe converter can do it in one line.

Thanks you for the feedback and a temporary solution.

Hi Robert,

I have updated the behavior and the change will be available in our next internal build coming on Monday. In the meantime I am attaching a sample project with locally built binaries just to verify this is the result you would expect. Let me know in case something is not correct on you side.

I downloaded project, reviewed it, and ran it.  It behaves as expected without the need to use autoGeneratingTile.

Thanks!

Hello Robert,

I am glad to here that. Those binaries will be available with the internal build on Monday. Let me know in case you found other issues.
I am also updating your telerik points for your feedback. Thanks for that.
