Retrieve only the fields shown in userdisp.aspx from User Information List

Question

I have built a Web Part in Visual Studio 2008 to show the current user's information (this is for WSS 3.0).

I have no problem iterating through all the fields in the SPListItem, but I want to filter out the fields that are NOT shown on the User Information page (_layouts/userdisp.aspx). I can't seem to identify the property to compare to. When I filter by Hidden = false, I still get SIP Address, Content Type, etc.

An explanation: When a user views their information from the user information list in one site collection, they see Account, Name, E-Mail, Job Title, About Me, etc. In a different site collection, we have added Department, Code and Branch. I want to create a Web Part that shows the visible fields, so I can deploy it across all site collections without customizing. One option is to make these fields required, and then filter by Required = true, but these are not necessarily required fields and I would have to edit every site collection for it to work.

Any suggestions on what property or properties to use? I used the WSS-3.0 tag for this question, as I think the answer would be different in SharePoint Foundation.

Answer 1

It seems that sharepoint gets this fields from one of the list view for user information list (Detail View I guess, I can't verify it exactly, because I always redirected to my host site). But you can check it:

var list = web.Lists["User Information List"];
var view = list.Views["Detail View"];
for (int i = 0; i < view.ViewFields.Count; i++)
{
     var fieldInternalName = view.ViewFields[i];
     ....
}
