My requirement is if click on three buttons all the buttons and text boxes styles are changing. but the both x:key styles are not changing. Please tell me the problem and solution asap. In my main application I am using may borders and grids if I give the styles with out key the style applying to all. I don't want that. I just want to apply styles to given key only.

Can you please give me the code how to write for your above solution. I am unable to add code under Loaded event of App.xaml.cs. Still I am pending for my problem. If I write your code in  Application_Startup in App.xaml.cs file it won't take. Thanks in advance.

To add the resourcedictionary at runtime. Make a variable of resourcedictionary and pass file name as parameter. Then add that resource into the MergedDictionaries. something like this: Write the following code under Loaded event of App.xaml.cs ResourceDictionary dictionary1 = new ResourceDictionary(@Theme1.xaml); ResourceDictionary dictionary2 = new ResourceDictionary(@Theme2.xaml); Application.Resources.ResourceDictionary.MergedDictionaries.Add(dictionary1); Application.Resources.ResourceDictionary.MergedDictionaries.Add(dictionary2);
