Hi Tirumala Manikanta,
Thank you for contacting Telerik Support.
Let me start with first that the
RadMaskedTextBox was migrated to
RadMaskedInput and the ExtendedTextBox was part of its ControlTemplate. It was also used in other controls in their older versions.
In order to help you to migrate your application, you can give use more information.
1. Which control from our UI for WPF suite you are using?
2. Have you set any custom style in your application?
We are looking forward to your answer.
Regards,
Dinko
