Gets or sets the name of a data field (or an xml element's attribute) which provides image gallery item thumbnail locations.
A string value that specifies the name of the required data source field.
The ThumbnailUrlField property is in effect if the ImageGallery extension is bound to a data source.
Use the ThumbnailUrlField property to specify the bound data source's data field (or an xml element's attribute) which stores the thumbnail URLs of image gallery items. The ThumbnailUrlField property maps the ImageGalleryItem.ThumbnailUrl (via the MVCxImageGalleryItem.ThumbnailUrl) properties of image gallery item objects to the specified data field's values.
If the ThumbnailUrlField property of a data bound image gallery is not defined, the control can automatically obtain item thumbnail URLs from a data field whose name is "ThumbnailUrl". You can also use the ImageGallerySettings.ItemDataBound property to manipulate an item's settings as required.
