Hi Admins.

I am developing an application which have the functionality to change the theme at rune time.

When i use the Telerik Themes. Message on the RadMessaageBox not shown properly (see attached image)

the code for displaying the MesageBox is

Is this theme problem that is not compatible with html tags.

Hello, Kashif,    

According to the provided screenshot, it seems that you are using the Fluent theme to your application. I have tested the provided code and it displays the message box as expected:

Have you changed the font of the message box? Because the different fonts may result in different result when rendering the text. 

By default we use GDI+ to measure the text, however, GDI+ is a known suspect for reporting wrong sizes of the text and this is also the case here. You can easily force the element to use GDI instead of GDI+ by setting the UseCompatibleTextRendering property to false and this should improve the rendering of normal text. However, for HTML-like text rendering, the possible solution that I can suggest is to use a suitable font.

I am looking forwrad to your reply.
