使标题字段在自定义列表定义中强制实施唯一值(SharePoint 2010) [英] Make Title field enforce unique values in custom list definition (SharePoint 2010)
问题描述
我有一个自定义列表定义,我试图将自定义的标题"字段重命名为名称",并使其强制执行唯一值.首先,我在自定义内容类型(Elements.xml)中引用了它:
I have a custom list definition, and I am trying to rename the custom 'Title' field to 'Name' and to make it enforce unique values. First, I referenced it in the custom content type (Elements.xml):
<FieldRef ID="{fa564e0f-0c70-4ab9-b863-0177e6ddd247}" Name="Title"/>
,然后在列表模板(Schema.xml)中:
and then in the list template (Schema.xml):
<Field ID="{fa564e0f-0c70-4ab9-b863-0177e6ddd247}" Name="Title" DisplayName="Name" Type="Text" AllowDuplicateValues="FALSE" Required="TRUE"></Field>
该字段已重命名,但是我可以添加具有相同标题的列表项.如果我进入字段设置页面,则强制唯一值"属性将设置为false.我做错了如何启用它?
The field is renamed, but I can add list items with the same title. If I go in the field settings page, the Enforce unique values property is set to false. How can I enable it, what I am doing wrong?
推荐答案
要完成这项工作,您需要添加:
In order to make this work you need to add:
Required="TRUE" EnforceUniqueValues="TRUE" Indexed="TRUE"
然后删除
AllowDuplicateValues
在列表定义的 Elements.xml 和 Schema.xml 中,对<Field>
进行操作.
To your <Field>
in both the Elements.xml and the Schema.xml of your list definition.
