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.
Do you need help with upgrading your AJAX, WPF or WinForms project? Check the Telerik API Analyzer
and share your thoughts.
