How to get SPList to expose a data entry form during “Add New Item”

Question

I think I've successfully created a list based on a custom content type but when I click on the "Add new item" link for the list, I see nothing except:

• a basic ribbon tab labeled "Edit" with icons for SAVE, CANCEL, PAST, CUT/COPY, ATTACH FILE and SPELLING
• two buttons labeled SAVE and CANCEL

The content type contains roughly a dozen items and I was hoping to have the "Add new item" link produce a "data entry form" with labels for the fields followed by textboxes for the value of the field. I would like the behavior of "add new document" prompt for "metadata" after the upload of a file.

I find that if I create the list using a template type of SPListTemplateType.DocumentLibrary (instead of SPListTemplateType.GenericList), then I "sort of" get the sort of effect I am looking for. That is, I get a "document information panel" with labels and textboxes as described which is good - but this only comes after a prompt for what file to upload (which is bad because I don't want to upload files into this list).

Here are key snippets of my code currently being tested from a Windows "scratch pad" application running locally on my SP2010 development machine:

private void CreateListBasedOnCT_Click(object sender, EventArgs e)
{
    using (var site = new SPSite(SiteUrl))
    {
        var web = site.RootWeb;
        var list = CreateList(txtListName.Text);
        list.ContentTypesEnabled = true;
        var agreement = CreateContentType(txtCTname.Text);    // get reference to the custom content type of the SITE
        list.ContentTypes.Add(agreement);                  // add to content type collection of the LIST 
        // remove the item content type; go to the LIST content type collection for removal
        SPContentType itemtype = list.ContentTypes["Item"];
        list.ContentTypes.Delete(itemtype.Id);
        list.Update();
        listBox1.Items.Add("END: The list has been created based on the content type");
    }
}
private SPList CreateList(string newListname)
{
using (var site = new SPSite(SiteUrl))
{
    var web = site.RootWeb;
    DeleteList(newListname);    
    var listID = web.Lists.Add(newListname, string.Empty, SPListTemplateType.GenericList);
    var list = web.Lists[listID];
    list.OnQuickLaunch = true;
    list.ContentTypesEnabled = true;
    list.Update();
    listBox1.Items.Add(newListname + " list created");
    return list;
}
}
private SPContentType CreateContentType(string newContentType)
{
    using (var site = new SPSite(SiteUrl))
    {
        var web = site.RootWeb;
        DeleteContentType(newContentType);
        SPField field = web.Fields.TryGetFieldByStaticName("ApprovingOffical");
        if (field == null)
        {
            var fieldNameInternal = web.Fields.Add("ApprovingOffical", SPFieldType.Text, true);
            var siteColumn = web.Fields.GetFieldByInternalName(fieldNameInternal);
            siteColumn.Group = "CustomED";
            siteColumn.Update();
        }
        var document = web.ContentTypes["Flexiplace Work Agreement"]; // instantiate the parent
        var teleworkCT = new SPContentType(document, web.ContentTypes, newContentType); // instantiate new CT
        teleworkCT.ReadOnly = false;
        teleworkCT.Group = "Custom ED";
        web.ContentTypes.Add(teleworkCT); // need to add CT to the collection before updating it with columns
        teleworkCT.Update();
        AddExistingSiteColumn(web, "ApprovingOffical", teleworkCT);
        AddExistingSiteColumn(web, "Date Modified", teleworkCT);
        AddExistingSiteColumn(web, "Job Title", teleworkCT);
        AddExistingSiteColumn(web, "Location", teleworkCT);
        AddExistingSiteColumn(web, "Government ID Number", teleworkCT);
        AddExistingSiteColumn(web, "Business Phone", teleworkCT);
        AddExistingSiteColumn(web, "E-Mail", teleworkCT);
        teleworkCT.Update();
        listBox1.Items.Add(newContentType + " content type created");
        return teleworkCT;
    }
}
