Question

New to WPF so I’m sure it’s an easy one this; for every control of a certain type/s, I want to set a property to the same value. The property is telerik:Theming.Theme and I would like to apply the same value to all telerik: controls. If there’s no way to do this then how do I use a resource to define this value and refer to the resource in the controls?

Thanks.

You may override the default value of any dependency property for a specific control type (precisely a specific type of dependency object) by DependencyProperty.OverrideMetadata in your application initialization code (e.g. the static constructor of your MainWindow):

Telerik.Windows.Controls.Theming.ThemeProperty.OverrideMetadata(
    typeof(SomeControlClass),
    new PropertyMetadata(SomeDefaultValue));

where SomeControlClass is the (base) class that you want to give a new default value for the Theme property, and SomeDefaultValue is the new default value.

Note also that Theming.ThemeProperty seems to be obsolete and will be replaced by StyleManager.ThemeProperty.
