tested on winui and android

Warnings: Element (warning): Microsoft.Maui.Controls.SolidColorBrush is already a child of Telerik.Maui.Controls.RadEffectsView. Remove ... before adding ... (x many) Element (warning): Microsoft.Maui.Controls.SolidColorBrush is already a child of Telerik.Maui.Controls.RadBorder. Remove ... before adding ... ``` ## Reproduction 1. A `ContentPage` inside a `NavigationPage` containing several Telerik `RadEntry` styled via **implicit styles** that set `BorderBrush` across multiple `VisualState`s (Normal/Focused/Invalid/ReadOnly/…). No custom `ControlTemplate` is applied; only `BorderBrush` (and background/text) setters. 2. Interact with the page, and with the entry control on it 3. There are warnings in the output

Hi Smadar,

The warnings are related to the RadEntry control, not to the RadButton. And they are visible on WinUI too, so not only android related. 

Regarding to the exception and all questions asked. I will send a reply to the ticket, so lets continue the communication there. This public item will be for the warnings on runtime.

Regards,
Didi
