Theme changing events?

[Swaroop]

Hello,

Ive built a Winforms RadForms application with VB.Net. The application contains several forms that contains several rad controls. The form contains several buttons when clicked changes the theme. But it takes around 3-4 seconds for the theme to change. Now what I want to achieve is the application must show a message box with the message- "Theme Changed" when the theme has changed. I was wondering if there are any events that can be fired during a theme change and found one event named "ThemeNameChanged".  I set it up like this:

Private Sub (source as Object, args As ThemeNameCahngedEventArgs) Handles Me.ThemeNameChanged

Msgbox("Theme Changed")

EnsSub

Then I switch the theme with the click of a button:

 

Private sub Button1_Click(...) Handles Button1.Click

ThemeResolutionService.ApplicationThemeName = "TelerikMetroBlue"

End Sub

But when click Button1 the theme changes but the message is not displayed once the theme has changed. So How Do I dsiplay a message when the theme has changed?

Hello, Swaroop, 

Setting the ThemeResolutionService.ApplicationThemeName property will style the entire application with the newly applied theme. However, in order to detect the theme changing in this case the ThemeResolutionService offers the ApplicationThemeChanged event:

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
