Content Type field on NewForm.aspx

Question

I have a custom list and I am using content types to add items to the list. I am using OOTB forms for new and edit items. One field that I see on the EditForm.aspx is the one that I hope I get on the NewForm.aspx also and it is the Content Type field. It is shown in the following screenshot. Do you know how to add that field on the NewForm.aspx page also?

EditForm.aspx

Thanks.

Answer 1

There is a unique query string parameter on the newform url that tells Sharepoint what form to render. You can put a content type field on a custom html or aspx page, then use web services to submit the item otherwise, you can't get that on the newform.

If you go to the list and use the ribbon to create each content type, you can snatch the URLs and then use those in your presentation logic for the users.

Answer 2

Unless you create your own URL to NewForm.aspx without parameters,
the ContentTypeId is by default present as a QueryString parameter.

So you can add some JavaScript to that single NewForm.aspx (edit in advanced mode) just before the table of the form, that matches by ContentTypeId and prints a header.

If you don't have SharePoint Designer add a ContentEditorWebPart to page.

    <script>
        JSRequest.EnsureSetup();
        var ctID=JSRequest.QueryString['ContentTypeId'];
        var titles={
            '0x0100223....010019ABEA5C55C59D4383F98D5A938894D8' : 'Expense',
            '0x0100223....02006C9B8D0CCE23024EA3A01C9A93FAFBB3' : 'Invoice',
        };
        var title = titles[ctID] || ctID;
        document.write( String.format('<h1 title="{1}">New 365CSI: {0}</h1>', title,ctID ));
    </script>

    <table class="ms-core-tableNoSpace" id="onetIDListForm">

Always get the correct ContentTypeId

After pageload the ContentType info is always present in:

WPQ2FormCtx.ItemContentTypeId
and
WPQ2FormCtx.ItemContentTypeName

But you better make sure you reference the correct WebPart (WPQ2 most of the time)
