Setting the Title property should update the header text:

 this.radPageViewPage1.Title = "test";

Changing the text of a Page runtime will update the page navigation view item, but the header element won't. Reselecting the page will update the header element text.

At design time:

1. Made hierarchy through Property Builder.

2. Set a custom image or text for a RadPageViewPage

Use the sample project and follow the illustrated steps in the gif file.

Expected: when you hover a page and it has sub pages, the popup is shown automatically. When you hove another page while the popup is still opened, it shouldn't remain opened.

Actual: when you hover a page and it has sub pages, the popup is shown automatically. When you hove another page while the popup is still opened, it should be closed.
