I am trying to change color of RadDatePicker when it comes to focused state. I usually get in the focus state by pressing the Tab key or after selecting a date value from the picker - then the background color of "DateTimePickerButton" becomes blue (see attachment).
I already have tried to change it using a UserThemeResources or by editing a ControlTemplate I had found here in forum. Unfortunately, all attempts without any luck. I can change BorderBrush, ForegroundBrush but Background stays unchanged.
My app uses multiple form controls, including a system ComboBox, where I run into same issue. Happily I was able to resolve the issue by setting "ComboBoxSelectedBackgroundThemeBrush". I can't find any related brush name in http://docs.telerik.com/windows-universal/controls/raddatepicker-and-radtimepicker/styling/raddatetimepickers-teleriknamedbrushes.
Would you please be so kind and tell me name of the "blue background focused brush" or recommend a workaround?
Thanks in advance
