Build powerful views of SharePoint content from across multiple site collections
The Lightning Conductor Web Part is a very easy to configure SharePoint List and Library rollup Web Part that can rollup SharePoint Content from across multiple site collections and web applications.
Unlike the Content Query Web Part (CQWP), the Lightning Conductor Web Part can aggregate SharePoint content from anywhere within your SharePoint farm. Instead of writing XSL to display multiple columns of information from SharePoint Lists, you can also configure a view with the Lightning Conductor Web Part without writing any code at all.
Using the simple wizard, select the Site Collections, Sites or Lists that you want included in the scope.
Rolling up SharePoint Content is easy with the Lightning Conductor Web Part. Using the Configuration Wizard, you can build your query within minutes to rollup SharePoint Content. You can choose where the content will be aggregated from, and filter by List Type, and Content Type. You can direct relevant content to your users by using the SharePoint Audience Targeting feature.
Check the columns you want to display
Once you have configured your Query, you can build your view without writing any XSLT. Simply choose the columns that you wish to display, setup filters, apply formatting, setup pagination and you are ready to display your rolled up content.
Building your view allows you to display multiple columns easily. For example, instead of just displaying the title column from your SharePoint Task Lists, you can display Title, Due Date, Status and Priority.
Built in views such as Calendars and Discussion threads
In context viewing/editing
When clicking a list item, you will never be taken away from the page containing the Lightning Conductor Web Part no matter where in the SharePoint farm your content resides. This allows users to use the data as though it belonged to the site that they are currently viewing.
