Issue in changing theme/skin of Silverlight RAD controls at runtime

[Shiv]

Hi,

I am facing issue in applying theme at runtime.
I am able to set the appl;ication theme by the specified code:

public MainPage()
{
     StyleManager.ApplicationTheme = new Office_SilverTheme();
     InitializeComponent();
}

My requirement is to change the application theme at runtime on change of my Theme/Skin Dropdown:

private void cmbThemes_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangedEventArgs e)
        {
            if (cmbThemes != null)
            {
               StyleManager.ApplicationTheme = new VistaTheme();
             }
        }

So, please provide a solution as displaying in the given example:

Thanks & Regards,
Shiv.

Hi Vanya Pavlova,

Please refer the original question in the thread as I said, that on application load in the MainPage usercontrol constructor by specifying the below code before calling "InitializeComponent()" I am able to change the Theme of the Application (working fine):

public MainPage()
{
 StyleManager.ApplicationTheme = new Office_SilverTheme();
 InitializeComponent();
}

Problem:   As per my requirement I need to reset the theme of the Application on change of my Combo-box as per the selected Theme which is not happening by the below code:

private void cmbThemes_SelectionChanged(object sender, Telerik.Windows.Controls.SelectionChangedEventArgs e)
{
        if (cmbThemes != null)
        {
         StyleManager.ApplicationTheme = new VistaTheme(); //This line of code is just for an example to change the theme.
        }
}


Please provide the solution for implementing such schenario.


Thanks,
Shiv

Hi Shiv,

There are a couple of possibilities to accoplish changing themes at run time. The first one is similar to the one demonstrated in our demos - both for the examples with Localization and modifying the Theme. Its main idea is that the element changing the language/theme is outside the main view - in the examples it is outside the main grid. The ContentPresenter inside is responsible for loading the page with a different theme. The RootVisual in the App.xaml.cs is set to be the SilverlightControl1.
The other possibility is to implement a navigation logic using the Silverlight Navigation Framework. Thus you may "map" to the correct page with its specific theme. 
Further information about setting the Theme may be found in our online documentation.
