Populate a tile style from resource dictionary

[band]

At the moment in my resource dictionary I have a telerik Tile control. When it's instantiated a second time I receive the follow error `Specified Visual is already a child of another Visual or the root of a CompositionTarget`

public void ListIcon()
{
    var tile = Application.Current.Resources["ListTile"] as Tile;
    Tiles.Add(tile);
}

app.xaml

<telerik:Tile x:Key="Calendar" TileType="Double" Background="#FF79256B" Group="Other">
    <telerik:RadCalendar x:Name="calendar"
                  FontFamily="Segoe UI"
                  FontSize="10"
                  controls:StyleManager.Theme="Windows8"
                  VerticalAlignment="Top" HorizontalAlignment="Center"
                  SelectionMode="Extended"
                  IsTodayHighlighted="True" ViewsHeaderVisibility="Collapsed"
                  SelectedDate="{Binding SelectedDate, Mode=TwoWay}"
                  Culture="en-US"
                  DayTemplateSelector="{StaticResource EventDayTemplateSelector}"/>
</controls:Tile>

 

Everytime a new user is logged in, ListIcon() is called. If I log out and log into a second user the error occurs. May I ask how do I resolve this.

Hello Band,

By default, every visual element declared as a resource in ResourceDictionary is sharing the same instance for all requests. If you want to change this behavior and create a new instance for each request you can set x:Shared attribute of the current visual element to False. But keep in mind that this attribute is valid only for WPF.

I hope that this helps.
