The DevExpress ASP.NET Image Gallery (ASPxImageGallery) control supports template technology, allowing you to customize a control's appearance and layout.
The look of the ASPxImageGallery control's default elements can be modified by using a specific template that defines how an element will be rendered by a client browser. This control allows you to create templates for the following elements.
You can apply templates for all identical elements within the control (using control level templates) or for a particular element (using item level templates). Each template can consist of a group of HTML controls. Each HTML control used in a template can be bound to the property value of the rendered item.
In this demo, the ItemTextTemplate and FullscreenViewerItemTextTemplate properties are used to display rich text formatting.
