如何在 Sharepoint 列表中管理基于列的访问控制? [英] How to manage column based access control in Sharepoint lists?

问题描述

我正在制作基于 Sharepoint 的问题跟踪门户.用户应该能够添加条目，但在条目本身中，我希望一列仅对特定的用户组(管理员)可见.有没有办法设置基于列的访问控制?

I'm making issue tracking portal based on Sharepoint. Users should be able to add entries, but in the entry itself I want one column to only be visible to a specific group of users (Administrators). Is there a way to set column based access control?

推荐答案

据我所知，在标准平台中是不可用的.另一方面，您可以做的是手工制作自己的 fieldcontrol

As far as I know that is not available in the standard platform. What you can do on the other hand is to handcraft your own fieldcontrol

所以在自定义 fieldtypes.xml 中

So in custom fieldtypes.xml

<FieldTypes>

  <FieldType>
    <Field Name="TypeName">MyInteger</Field>
    <Field Name="ParentType">Integer</Field>
    ...
    <Field Name="FieldTypeClass">xxx</Field>
  </FieldType>

在 sitecolumns.xml 中

and in sitecolumns.xml

  <Field ID="xxx"
      Name="xxx"
      DisplayName="xxx
      Description="xxx"
      Group="xxx
      Type="MyInteger"    
      DisplaceOnUpgrade="TRUE"
  />

并在您的字段控件中

public class MyInteger: SPFieldNumber
{
    public MyInteger(SPFieldCollection fields, string fieldName)
        : base(fields, fieldName)
    {
    }

    public MyInteger(SPFieldCollection fields, string typeName, string displayName)
        : base(fields, typeName, displayName)
    {
    }


    public override BaseFieldControl FieldRenderingControl
    {
        [SharePointPermission(SecurityAction.LinkDemand, ObjectModel = true)]
        get
        {
            Microsoft.SharePoint.WebControls.BaseFieldControl ctl = 
               new MyIntegerControl();
            ctl.FieldName = InternalName;
            return ctl;

        }
    }

    }

在 MyIntegerControl 中你可以做任何你想做的事情(很多覆盖)，但一个例子是:

and in the MyIntegerControl you can do whatever you want (lots of overrides), but an example is:

protected override void CreateChildControls()
{
    base.CreateChildControls();
    if (this.ControlMode == SPControlMode.New || 
        this.ControlMode == SPControlMode.Display)
    {
      // check that use is admin and display value
    }
}
