Windows8Touch StyleSelector for ListBox not working

[Muhammad Ummar]

Hello,

I am facing issue with RadListBox control styling issue when using Windows8Touch theme. Following is the description

1- I want to use different styles for each RadListBoxItem so I am using StyleSelector , It is working fine for all other themes, but as soon as I switch my application to Windows8Touch,  StylesSelector stopped working. On some drilling down I came to know that in Windows8Touch "StyleSelector.SelectStyle" is not being called.

2- Following is the code for StyleSelector

public class LstStyleSelector:StyleSelector
    {
        public Style Red { get; set; }
        public Style Blue { get; set; }
        public override Style SelectStyle(object item, DependencyObject container)
        {
            if (item != null)
            {
                if (((KeyValuePair<int, string>)item).Key % 2 == 0)
                    return Red;
                else
                    return Blue;
            }
            else
                return Red;
        }
    }

3- Following is the XAML

<Grid>
        <Grid.Resources>
            <Style x:Key="reditem" TargetType="{x:Type telerik:RadListBoxItem}">
                <Setter Property="Background" Value="Red"/>
            </Style>
           
            <Style x:Key="bluitem" TargetType="{x:Type telerik:RadListBoxItem}">
                <Setter Property="Background" Value="Blue"/>
            </Style>
            <local:LstStyleSelector x:Key="itemContainerStyle" Blue="{StaticResource bluitem}" Red="{StaticResource reditem}"/>
           
        </Grid.Resources>
        <telerik:RadListBox x:Name="lstbx" VerticalAlignment="Center" DisplayMemberPath="Value" ItemContainerStyleSelector="{StaticResource itemContainerStyle}"/>
    </Grid>

4- Here I am setting theme in App.xaml.cs

private void Application_Startup(object sender, StartupEventArgs e)
{
    //StyleManager.ApplicationTheme = new Windows8TouchTheme(); //StyleSelector not working.
    StyleManager.ApplicationTheme = new Office_BlackTheme(); //StyleSelector working fine!
}

Please help me out on this issue. I am using Q1 2013.

Regards.
