The way the pane tabs are rendered is controlled by the TabView
property of the RadSlidingPane. The TabView property
uses the Telerik.Web.UI.RadSplitterSlidePaneTabView enumeration
which has the following values:
- TextAndImage (default) - both the Icon and Title are displayed
in the tab
- TextOnly - only the Title is displayed
- ImageOnly - only the Icon is displayed
You can set the url of the icon using the IconUrl property. To set the title of the pane use the Title property.
