hi, I need change the theme of the control with custom template.
I changed the theme of my silverlight app and some controls(custom Template) remain with the same theme.
what can I do for change the theme of these controls to be the equals of others?
example:
customCombobox, radwindow, expander >> theme default win7
changed theme
cusmtomCombobox >> win7 -- radwindow, expander >> win8 theme
I'm use blend for edit a copy of current theme.
PD. in the image can see I have three combobox, two of them with different theme
thankss...
have a nice day.

Hello Luis,
Thank you for contacting us.
In our online documentation you will find an article, which demonstrates how to switch themes at runtime, here.
Since the templates are isolated in separate resource dictionaries you could add and clear those you need within ComboBox's SelectionChanged event handler.
Can you please take a look at the resource above and let me know how it corresponds to your needs?

I dont have problem to change the theme in runtime.
the goal is change the controls with custom template, that controls don't change.
I use a copy of current template and modified the template, but saved the theme of that moment.
how change the theme of custom template control?

Hello Luis,
Thank you for getting back to us.
Predefining the template of custom controls is not supported with standard assemblies.
If you use NoXAML binaries combined with implicit styles, you could achieve your goal.
Provide the DefaultStyleKey for the element, some template and switch it in the same way as proposed in our documentation.

Hi Luis,
Please mind that our implicit styles theme mechanism works with our default control templates. You may modify the implicit styles setters for every control but as soon as you have custom control template, you will lose the theming. This is expected as the control templates holds practically everything - the Visual States and the Visual Structure of the control which are theme specific.
There are two approaches you might choose from in your case:
1. Have a separate control template per every theme you have and merge it after our style files resource dictionaries. For the purpose just modify the default RadExpander template that we provide. Do not forget to clean the merged dictionaries and add the custom control templates back every time you switch theme. Let me know if you need further explanation or assistance with this approach. I highly reccomend this approach.
2. You might keep a single control template for every theme you have. However you'll need to apply a predefined theme-based RadExpander brushes everytime you change theme (for example on button click).
For the purpose you might use the following approach:
- create a Brush property with predefined value per each theme you have and listen for property changed:
- traverse the viusal tree to find the HeaderPanel of radExpander. For example:
- now apply the new Brush to the Expander Header/Content:
It will be very helpful if you are sending us runnable samples rather than code snippets so that we can inspect them and get back to you with faster responses.

var grid = this.ColorRadExpander.ChildrenOfType<Grid>().FirstOrDefault(g => g.Name == "HeaderPanel");
if (grid != null)
{
grid.Background = new SolidColorBrush(Windows8Palette.Palette.AccentColor);
}
- now apply the new Brush to the Expander Header/Content:
var binding = new Binding("HeaderAccentBrush");binding.Source = this.ColorRadExpander.Content;grid.SetBinding(Grid.BackgroundProperty, binding);It will be very helpful if you are sending us runnable samples rather than code snippets so that we can inspect them and get back to you with faster responses.

hi, I changed my Implementation of the controls about the static template.
I have an inherited class from radcombobox but when I change the app's theme, the radcombobox doesn't change
I put a style base on radcombobox but nothing....
some idea?
thanks have a nice day
public class ComboExport : RadComboBox{ public ComboExport() { this.style = app.resources["style"] as Style; }}0
Hi Luis,
The reason for this is that you have to merge the custom style every time you switch theme. For the purpose I suggest that you create new resource dictionary and add the custom style in it. You might find a sample project where this is demonstrated.

Hello Luis,
It is hard for us to say what might cause this unwanted behavior on theme switch without knowing more details on your case - are you using implicit styles with NoXAML binaries, do you have any custom styles applied, which controls do you use? It will be better for us if you could send us a sample runnable project where we can reproduce it and get back to you with more adequate feedback.
P.S. To be able to send us your runnable project you need to open new support thread. The reason is quite simple, really - we do not want people to share their projects publicly. Another advantage of using support threads is the shorter response time compared to forum posts.
