Adding Images to Tabs
Each RadTab has a set of properties you can use to add images to the tab. You can simply add a single image to each tab, or you can add separate images that reflect the state of the tab.
The image appears to the left of the tab's text (unless you are using a right-to-left orientation, in which case it appear to the right of the tab's text). By setting the Text property to an empty string, you can create tabs that are labelled solely with images.
The following properties let you add images to tabs:
ImageUrl specifies an image that is added to the tab. This image is always used, unless you set one of the other properties to specify an alternate image to use in a specific state.
SelectedImageUrl specifies an image that is used when the tab is selected.
HoveredImageUrl specifies an image that is used when the mouse is over the tab.
DisabledImageUrl specifies an image that is used when the tab is disabled.
To set the image properties at design time, use the RadTabStrip Item Builder.
The following example uses the ImageUrl and SelectedImageUrl properties to create a RadTabStrip that adds images to the top-level items:
