Our users upgraded from 7.0 to 7.5 complained about the user lookup dialog – on 7.0 it used to be a dropdown, whereas on 7.5 it’s a popup similar to the LAN client.

Sorry for the chopped image, I had to hide the name and was too lazy to re-run on the eval db.

The problem is the popup takes a couple seconds to come up on IE7, sometimes more on slow machines or slow connections – it’s a bit irritating.  After a brief phase of denial (how dare they refuse the New and Improved way, etc) I set to work.  Had to struggle a bit with the combination of available properties but finally got it working.  Configuring lookup is definitely a big pain on the web client!  This is the winning combo:

• Display Mode = DropDownList
• Display Property = UserInfo.UserName
• Lookup Entity Name = User
• Lookup Binding Mode = Object
• In the Lookup Pre Filters, add a filter on “Enabled” (make sure the property is populated as System.Boolean, and set OperatorCode to “=”) and filter value of “true”

The DropDown style lookups are a bit more picky on the parameters than the regular lookup, because they actually use NHibernate parameters instead of inline HQL.  In general I would say it is a good thing to use parameters, though in this case it makes it a bit harder for us to hack around the limitation of the control.

Data binding works fine, the only big problem I have found is that it sorts by first name instead of last name for some reason (which you can’t really see in the screen shot as I removed the last name but you can imagine).
