How do I display a window or page inside an Item tab?

[Hussein]

How can I, for example, when clicking on a specific button, make its event open or display me a window or page in a new tab item dynamically, and all I have to do is select the page or window to display and it moves me to it and opens it inside a new tab item just like the Google Chrome browser

Hello Hussein,

To achieve this requirement, the AddingNewTab event of the RadTabbedWindow control could be utilized. This event will occur when the add button is clicked. Then, you could create a UserControl that will contain the data to be displayed (for example, when a new tab is opened in the browser, it will display a search bar and buttons that lead open links). This UserControl could be set to the Content property of the e.Item property of the event arguments. The elements inside the UserControl that will function as the ones in the browser could be buttons that when clicked, will add a new RadTabItem to the RadTabbedWindow control.

With this being said, I have prepared a sample project that contains an implementation of the above suggestion. In order for the project to run, the Xaml version of our assemblies for the .NET 7 would have to be added. Could you give it a try?
