How to change the Background for StackPanel with theme?

I want to use change theme function, but I found that the background color of stackpanel will not change with theme setting. The default background color of stackpanel only act when first app start, then we change the theme, it does not change its color.
The code is :

<Window x:Class="MainWin.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        Title="MainWindow" Height="350" Width="525">
 
    <telerik:RadDocking x:Name="radDocking" HasDocumentHost="False" AllowUnsafeMode="True">
 
        <telerik:RadSplitContainer InitialPosition="DockedTop" Height="50" Orientation="Vertical">
            <telerik:RadPaneGroup>
                <telerik:RadPane PaneHeaderVisibility="Collapsed">
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition></RowDefinition>
                            <RowDefinition></RowDefinition>
                        </Grid.RowDefinitions>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition></ColumnDefinition>
                            <ColumnDefinition></ColumnDefinition>
                        </Grid.ColumnDefinitions>
                        <StackPanel Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" x:Name="Part1">
                            <telerik:RadButton Content="Office_Blue" Width="100" Height="30" Click="RadButton_Click"/>
                            <telerik:RadButton Content="Expression_Dark" Width="100" Height="30" Click="RadButton_Click"/>
                        </StackPanel>
                        <StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch"  Grid.Row="1" Grid.Column="0"   x:Name="Part2" >
                            <Label Content="Test1" HorizontalContentAlignment="Center" VerticalContentAlignment="Center"/>
                        </StackPanel>
                        <StackPanel Grid.Row="1" Grid.Column="1">
                            <telerik:Label Content="Label 2"  HorizontalAlignment="Center" x:Name="Part3"/>
                        </StackPanel>
                    </Grid>
                </telerik:RadPane>
            </telerik:RadPaneGroup>
        </telerik:RadSplitContainer>
    </telerik:RadDocking>
</Window>

        }
 
        private void RadButton_Click(object sender, RoutedEventArgs e)

            RadButton btn = sender as RadButton;
            if (btn.Content.ToString() == "Office_Blue")
            {
                SetGlobalTheme(new Office_BlueTheme());
            }
            else
            {
                SetGlobalTheme(new Expression_DarkTheme());
            }
        }
 
 
        public static void SetGlobalTheme(Theme theme)
        {
            StyleManager.ApplicationTheme = theme;
 
            foreach (Window w in Application.Current.Windows)
            {
                SetThemeToVisualObject(w);
            }
        }
   
        public static void SetThemeToVisualObject(DependencyObject myVisual)
        {
 
            foreach (object o in LogicalTreeHelper.GetChildren(myVisual))
            {
                if (o is FrameworkElement)
                {
                    if (o.GetType().AssemblyQualifiedName.StartsWith("Telerik.Windows.Controls"))
                        StyleManager.SetTheme((FrameworkElement)o, StyleManager.ApplicationTheme);
 
                    SetThemeToVisualObject((FrameworkElement)o);
                }
            }
        }
    }
}

In the MainWindow() constructor, if we use

StyleManager.ApplicationTheme = new Expression_DarkTheme();

then we start the app, we will find the StackPanel is dark,
However, if we use

StyleManager.ApplicationTheme = new Office_BlueTheme();

the StackPanel is white.

Click button in UI will not affect the background of Stackpanel.

How to solve this?

SelectedIndex

Hi

I am making a WPF application where i use the Microsoft Kinect as a input device.
So if i want to acces my Gridview, i will need buttons to select the row selection to go up and down.
     1.Since i have a Click system with my Kinect device, i only need a system to select the rows?
     2. When i select a row, i want a pop-up window with the details of the row, like NAME, EMAIL, SUBJECT and TEXT.
                - I have no idea how to do this?

How can i do this, I found things on your forum that includes RECORDS, but since u dont use them anymore, im struggling to find my way.
This is what i got

private void Button_Click(object sender, RoutedEventArgs e)

{

int i = this.radGridView.Records.IndexOf(this.radGridView.SelectedRecord);

int nextCurrentIndex = i + 1;

if (nextCurrentIndex < this.radGridView.Records.Count)

{

Record nextCurrentRecord = this.radGridView.Records[nextCurrentIndex];

nextCurrentRecord.IsSelected = true;

}
