Trouble setting Theme at runtime

[Dan Weese]

I am trying to change the theme of some of the RadControls at runtime. In the documentation, I found 2 ways to set the theme, neither of which work. I can set the theme at design time no problem.

StyleManager

 

.SetTheme(radSchedulerMain, new Office_BlackTheme());

 

radSchedulerMain.SetValue(

StyleManager.ThemeProperty,new SummerTheme());

 

 

With both methods, I get "There is no source code available for the current location", then "Index was outside the bounds of the array". How do I get past this problem?? Exception details below.

System.IndexOutOfRangeException was unhandled
  Message="Index was outside the bounds of the array."
  Source="PresentationFramework"

Hi Dan Weese,

I have absolutely no idea why it fails. I have created example project for you that displays RadScheduler with 3 buttons below that switch scheduler's theme. If you manage to make it crush with your exception please send it back so we can debug it here. I hope the attached project will help you.

Best wishes,

OK, I got that working on the Scheduler control and the Expander control on my form, but I'm guessing I can't set the theme of the RadRibbonBar from a RadRibbonComboBox contained on the RadRibbonBar?

 

private void OfficeBlue_Selected(object sender, RoutedEventArgs e)

 

{

radSchedulerMain.SetValue(

StyleManager.ThemeProperty, new Office_BlueTheme());

 

radRibbonBar_Main.SetValue(

StyleManager.ThemeProperty, new Office_BlueTheme());

 

radExpanderMain.SetValue(

StyleManager.ThemeProperty, new Office_BlueTheme());

 

}

Throws the same error I reported earlier, but ONLY when setting the theme on the ribbon. If I comment it out, it works fine. It behaves this way using a combo, or buttons like you had in the example.

Hi Dan Weese,

Yes - you are correct - we have tihs issue in ribbon bar currently. we are working on fixing it. You can however use the application theme with ribbon bar, but you can't change it in runtime.

Kind regards,

hi,

Is there any change about that issue? I can change RadRibborBar Theme at runtime but buttons on gallery go to invisible.And if I change in xaml statically ( telerik:stylemanager.theme:xxxx) makes same problem, if remove that (telerik:stylemanager.theme:xxx) from line everything  is ok.

Thanks

Hi,

I solved my problem.Behind code dynamic theme changes can be seen on radribbon galery when theme changed in ribbonbar(which include ribbon galery) , but buttons can not be seen.

SOLUTION : Independently, change the theme of ribbon galery dynamically also.(if you use static, you must set theme to ribbon galery also, not only ribbon bar).

Thanks

[Hidayet ÇELEN]

Hi,

This is nıot absolutely solved.If I define telerik:stylemanager.theme="Office_Black" in ribbonbar (in xaml), I must define telerik:stylemanager.theme="Office_Black" in Ribbon Galery.If one is Office_Black , other one is Office_Blue(or any other theme differ than Office_Black) Ribbon Galery's buttons are going to invisible.So, theme of Ribbon Galery must be defined and be same with theme of Ribbon Bar , if Ribbon Bar theme is defined.Otherwise , buttons are invisible.

When I want to change theme of Ribbon Bar in code behind (runtime), the buttons of Ribbon Galery are going to invisible.Also, I change the themes of Ribbon Bar and Ribbon Galery at same time and set two's to same theme, but still buttons are invisible.

What's wrong? What's the absolute solution?

sorry,

screenshots are here.Abnormal is after dynamic change.Normal is inital state of window.

Thanks

Hi Hidayet ÇELEN,

We posted an answer to the support ticket you opened by I will paste it here as well, if anyone else should encounter the same issue.

This issue is logged in our PITS where you can track it. In the meantime you can workaround it using the approach illustrated in the attached example.
