CatalogItemImageZoomControl Class

A catalog Item image zoom control. Introduced in v2.5.

Remarks

The CatalogItemImageZoomControl is a sub control of the CatalogItemImageControl. It allows Items with unlimited Item detail photos to display them to the shopper and viewed with a thumbnail slider-type navigation between photos. The control also provides functionality for an optional zoom feature for each Item detail photo.

The CatalogItemImageZoomControl will automatically be used by the CatalogItemImageControl when its EnableZoom property is set to true, and at least one Item detail photo file can be found for the Item.

The images used for the Item detail photos are managed in Item Maintenance using the "Item Image" pop-up and are stored in the Site folder designated by the "Item Detail Folder Name" setting in the Path tab of the Site Configuration settings.

Image Processing

The functionality of the CatalogItemImageZoomControl renders four different variations of each Item detail photo. These are:

Item Image Variation	Description
Item Detail Photo	The rendered version of the of the image when the page loads.
Item Detail Thumbnail	The rendered small version of the Item Detail Photo found in the thumbnail slider.
Item Detail Zoom	The rendered large version of the Item Detail Photo contained and cropped within the mouseover zoom window.
Item Detail Pop Up	The rendered large version of the Item Detail Photo contained within the zoom pop-up.

The control handles the creation of optimized versions of the uploaded Item detail photo for use with each of the variations.

Tip:

When creating your images for use as Item Detail photos, save them at the maximum displayed resolution and pixel dimensions.

The CatalogItemImageZoomControl downsizes versions in the system image cache at natural dimensions based on the image width and height settings for each variation.

Property Usage

Properties Inherited from the Base CyberStoreBaseControl

Override Properties
Contextual Properties

Override Properties

When the IgnoreControl property is set to true, all processing of a control is skipped, and the control's Visible property is set to false ensuring that it is not rendered in the resulting CyberStore page.

Contextual Properties

Contextual properties define specific details about the current instance of the control based on context. Context can be set by any number of factors including the log in state of the Shopper, the Site being visited, or the properties that have been established for a control.

The AttributesBag property is used internal to control processing and is the collection of attributes, or properties, and their values based on how the control is configured. The attributes in this property are set by processing the SitePages.config file as well as any specific declared property values in any registered sub controls. It allows for the passing down of all properties to a control and any registered sub controls.

The ComConfig, UserData and Site_ID properties are read-only values made available to all CyberStore controls to aid in processing and establishing context about the Site and Shopper.
