Properties

	Name	Description
	AccessKey	Gets or sets the access key that allows you to quickly navigate to the Web server control. (Inherited from WebControl.)
	Adapter	Gets the browser-specific adapter for the control. (Inherited from Control.)
	AllowDragDrop	Set to true to allow the user to drag a thumbnail to another position in the thumbnail control. Because the state of the image is not changed at all, the image will have to be reordered on the server side. Use the ThumbnailDrop event on the server side and the ThumbnailDropServer event on the client side.
	AllowedPaths	Gets a paths collection from where the control can retrieve data for annotations, images, etc. It can include absolute or relatives paths, and URLs. (Inherited from WebViewerControl.)
	AllowMultiSelect	Set to true to allow the user to select multiple thumbnails with a CTRL-Click. If set to false, only a single thumb can be selected at any time. Use SelectedIndexes to get the individual selections.
	AppRelativeTemplateSourceDirectory	Gets or sets the application-relative virtual directory of the Page or UserControl object that contains this control. (Inherited from Control.)
	Attributes	Gets the collection of arbitrary attributes (for rendering only) that do not correspond to properties on the control. (Inherited from WebControl.)
	AutoDragDrop	Set to true when AllowDragDrop is also true, the thumbnail control will automatically handle thumbnail rearranging with linked viewers. It is not necessary to automatically save a reordered image server-side everytime a drag drop event is raised; the thumbnail control will request the correct image and annotation layer from the server, regardless of the thumbnail order. The client side method getThumbnailOrder() will return the current order of the thumbnails in the control. When returning from the server after saving the reordered image, the client side method Invalidate() should be called.
	BackColor	Gets or sets the background color of the Web server control. (Inherited from WebControl.)
	BindingContainer	Gets the control that contains this control's data binding. (Inherited from Control.)
	BorderColor	Gets or sets the border color of the Web control. (Inherited from WebControl.)
