Many SharePoint lists and document libraries can be added to a web part page with a simple drag and drop operation. Web parts are easily customizable to suit your purposes and can display a summarization of information depending on the parameters you supply to the web part.
There are some technical and security limitations that restrict 3rd party non-Microsoft software in our shared hosting environment. Custom web parts are generally not compatible with shared hosting. We also apply updates and patches which may disrupt extensively programmatically altered sites.
SharePointHosting.com offers many 3rd party web parts – please request a quote for exactly what software you require. Technical support for custom software: We support the hosting component (server, data base, connectivity) while the 3rd party developer supports the custom code – additional paid software support may be available on a case by case basis. Customers should be aware that custom web parts can impact the security and stability of their sites, and may even prevent their sites’ successful migration to future versions of SharePoint.
In this SharePoint screencast we demo a custom web part we currently provide.
