How to deploy Enterprise Lookup?
Unpack "EnterpriseLookup.zip" file , then run 2 bat scripts - installLicenseManager.bat and install.bat from unpacked folder. First script will install IT-Dev license tools, second will install Enterprise Lookup and activate Enterprise Lookup features. That’s all. Yes, it is that simple.

Does Enterprise Lookup required activation of any features?
All Enterprise Lookup features are activated during its installation.

What are requirements for Enterprise Lookup?
Because Enterprise Lookup uses AJAX, before installing it you need to ensure that you are using Dot Net Framework 3.5. To run AJAX some modifications in web.config file are required too, but Enterprise Lookup will do it for you while deploying.

Does Enterprise Lookup support multiple WFE farms?
Yes, it does. When you deploy solution with Enterprise Lookup, SharePoint deployment framework distributes the component on all servers in farm and allows you to use it in network load balanced (NLB) environment.

Does Enterprise Lookup support Office client applications?
On basic level only, since Enterprise Lookup does not support view filtering in Office client applications. In Document Information Panel it will behave like standard lookup control with unfiltered items, but you will be able to edit data. This is because lookup fields handling in Office client is hardcoded and there is no possibility to override it.

Does Enterprise Lookup work in Datasheet View (Excel DataGrid)?
No, it doesn't. The reason is similar to Office client, but Datasheet View has even more restrictive behavior than Office client apps.

Does Enterprise Lookup work in SharePoint Designer customized forms?
No, Enterprise Lookup does not support customized forms for Sharepoint lists.

Does Enterprise Lookup work with customized form templates on target list?
No, Enterprise Lookup does not support custom form templates.

Is Enterprise Lookup Code Access Security (CAS) compliant?
No, it is not, since Enterprise Lookup is installed in Global Assembly Cache (GAC)  like all builtin SharePoint field types. Placing a field type control in bin directory causes applications external to portal webapp, (ie. SharePoint Designer, SharePoint Manager) fail when they come across a list that uses this field type.

Can I select multiple values in Enterprise Lookup?
Yes, exactly in the same way as in build-in lookup field, or in build-in user field in case of using resolving functionality.

Does Enterprise Lookup works with other components?
Yes, provided that other components do use System.Web.Extensions from Dot Net Framework 3.5. If they required System.Web.Extensions from other version of Dot Net Framework, Enterprise Lookup will not work.

How can I convert build-in lookup columns to Enterprise Lookup?
To do this you need to use Filtered Lookup setting page located in Site Actions.

Is it possible to create cross site collection links with Enterprise Lookup?
No, this is not supported scenario.
