The enum element sets the specified registry subkey to a specified value or a list of registry subkeys to values chosen from a drop-down list when a policy setting is enabled through the Group Policy Object Editor.

Syntax

<enum    id="<placeholderID>"
         clientExtension="<placeholderGUID>"
         key="<placeholderRegKey>"
         valuename="<placeholderName>"
         required="true|false" >
     <item> … </item>
</enum >

Attributes

Attributes	Required	Description
id Attribute	Yes	A mapping to the enum element.
clientExtension Attribute	No	The client-side extension will process, on the client computer, the particular settings represented by the enum element.
key Attribute	No	The registry key location under which the registry value will be created.
valueName Attribute	Yes	The registry value that will be configured for this specific policy element.
required Attribute	No	Requirement to enter a value in the parameter box.

Child elements

Element	Required	Description

Note

For simplicity of documentation, nested elements located one level down, known as child elements, will only be described for a given element.

Remarks

The enum element is generally associated with a drop-down list parameter in the Group Policy Object Editor.

The enum element will require a matching dropdownList element in the corresponding .adml file with id that matches as declared in the enum element.

Examples

This XML fragment is an example of an enum element thatis associated with a choice of three values with different display names in a drop-down list.

        <enum id="Sample_Dropdownlist_Box" 
                 valueName="Example2DropDownList" required="true">
          <item displayName="$(string.Sample_DropDownList_First)">
            <value>
              <decimal value="1" />
            </value>
          </item>
          <item displayName="$(string.Sample_DropDownList_Second)">
            <value>
              <decimal value="2" />
            </value>
          </item>
          <item displayName="$(string.Sample_DropDownList_Third)">
            <value>
              <decimal value="3" />
            </value>
          </item>
        </enum>

This XML fragment is an example of an enum element that is associated with a choice of two sets of values (defined in ADM files as an ACTIONLIST) with different display names in a drop-down list.

     <elements>
        <enum id="enum_example" valueName="exampleValueName" required="true">
          <item displayName="$(string.displayChoice1)">
            <value>
              <decimal value="1" />
            </value>
            <valueList>
              <item key="Software\Policies\Examples\1" valueName="1">
                <value>
                  <decimal value="3" />
                </value>
              </item>
              <item key="Software\Policies\Examples\2" valueName="2">
                <value>
                  <decimal value="3" />
                </value>
              </item>
            </valueList>
          </item>
          <item displayName="$(string.displayChoice2)">
            <value>
              <decimal value="2" />
            </value>
            <valueList>
              <item key="Software\Policies\Examples\1" valueName="1">
                <value>
                  <decimal value="1" />
                </value>
              </item>
              <item key="Software\Policies\Examples\2" valueName="2">
                <value>
                  <decimal value="3" />
                </value>
              </item>
