This example demonstrates a RadTabStrip that contains buttons in its tabs. We have used the Children collection of the tab item to place a RadButtonElement inside it. We have also set some margin of the ImageAndTextLayoutPanel to make room for the button element as placed directly in the tab item it doesn't become part of the tab item layout.
There's an event handler attached to the button element which gets the parent element and sets its Visible property to Collapsed thus making the button element behave like a close button.
