Virto Cross Site & Cascaded Lookup is a powerful tool intended to use for SharePoint information, and for joint display of associated data from several distinct sources including lists and sites. The component quickly cross-references existing data from a list or site and then applies a combination of filters to reduce the number of options presented in the drop down menu of your lookup field and eliminating the possibility for error as a result of incompatible values.
How to use Cross Site Lookup
As an example, we will do a case where you need to aggregate information from a list of clients which are grouped by countries and cities. We have created three lookup fields with the dependence country -> city-> client. This means that when a user adds a new item to the list, he selects a country and a list of cities of the country will be displayed accordingly. And when the list of cities is defined, the same happens with clients list. Enter title of the lookup and start typing a country name. The list of countries will be displayed. Click on the required country and use the arrow button to add this country to the lookup. As you add countries to the lookup, the list of cities will change accordingly. And as you select cities, the list of clients will change as well.
Though there are a number of products that offer the same functionality on the market, Virto Cross Site & Cascaded Lookup has a set of clear advantages. First, it integrates features of two distinct components, Cross Site Lookup and Cascade Lookup. Second, it provides users with additional features like advanced filtering and displaying additional columns for loo kup list items.
Virto Cross Site & Cascaded Lookup is the only product that effectively combines two components: provides users with extended tools for advanced displaying of SharePoint data, and with a cost that is less than the majority of SharePoint web parts with similar functionality.
