Why some field from content type never show?

Question

I create a document list called Publication groups, whose default content type is Publication. In the content type publication, there are some fields such as item no, kit number and so on.

But I can never see the project field in the browser. I never set it to hidden. What may possible lead to this? Thank you very much.

PS: I am going to Column Order page, trying to set visibility of some column.

Eidt:

I used CSOM code to check the hidden property of this field in Visual Studio. The hidden property is false. So it is not set to be hidden. But it doesn't show in the page. What could be wrong??? Thanks.

Answer 1

Check the values of SPField.ShowInNewForm, ShowInDisplayForm and ShowInEditForm. You can do that with PowerShell.

Open SharePoint Management Shell and run the following script

$web = Get-SPWeb http://YourSiteUrl
$list = $web.Lists["YourListName"]
$field = $list.Fields["YourFieldName"]
$field.ShowInNewForm

If ShowInNewForm is False you can set it to True

$field.ShowInNewForm = $true
$field.Update()

Do the same for ShowInDisplayForm and ShowInEditForm.

Answer 2

You'll need to make the column visible from the content type setting. For that you'll need to goto list setting, click on the content type and there you can set the order of the columns and also which fields are visible on dispaly, edit and new forms. Do let me know if you need a complete tutorial.
