Connectability is a standard protocol that is supported within a SharePoint environment. CorasWorks navigation and roll-up components can utilize the connectability interface so CorasWorks web parts can “talk” to one another and one web part can receive information from another web part. This information can be used to alter the data displayed within the current web part.
You can make the web part connection from either web part by using the Connections option on the web part menu.
You can only activate a connection when the page is in Design mode. Once in Design mode, access the web part menu and select Connections. Then specify the type of connection you want and the web part you want to connect to.
This type of connection allows you to provide a list of URLS to another web part. It allows you to set up your site information within one web part and have its setting reflect within this web part. The SPS WVA will not accept information from any other web part.
