Configuration Manager actions can be displayed according to specified conditions. The conditions are defined by the following:

Regular expressions
Method calls
Security permissions

Regular Expressions

Regular expressions allow you to apply string-based search patterns. The following elements specify a regular expression for an action:

Element	Description
`MatchPattern`	Specifies the pattern to search for.
`MatchValueToTest`	Specifies the value to compare against. The value following `##Sub` is a property on the selected object. The property must not be lazy and must exist on the select object.

The following action displays a dialog box whenever the specified pattern (MS_ASYNC_RAS) matches the selected object's AddressType property:

<ActionDescription ActionVerb="Properties" Class="ShowDialog">  <ShowOn>  <string>DefaultContextualTab</string> <!-- Show on Ribbon -->           <string>ContextMenu</string> <!-- Show on Context Menu -->   </ShowOn>  <MatchPattern>MS_ASYNC_RAS</MatchPattern>  
 <MatchValueToTest>##SUB:AddressType##</MatchValueToTest>  
 <DialogId>AsyncRasSenderAddress</DialogId></ActionDescription>

Method Calls

An action can be shown depending on the result of a method call. The ActionDescription child element ActionStateAssembly defines the assembly, type, and method to be called. If the method returns true, the action is shown; if the method returns false, the action is hidden.

The following XML calls a method named EnableDecrementPriorityMenu in the assembly AdminUI.Addresses.dll:

<ActionDescription>  
 <ShowOn>  
    <string>DefaultContextualTab</string> <!-- Show on Ribbon -->         <string>ContextMenu</string><!-- Show on Context Menu --> </ShowOn> <ActionStateAssembly>  
  <Assembly>AdminUI.Addresses.dll</Assembly>   <Type>Microsoft.ConfigurationManagement.AdminConsole.Addresses.AddressUtilityClass</Type>  
  <Method>EnableDecrementPriorityMenu</Method> </ActionStateAssembly>  
</ActionDescription>

The method is implemented in a .NET Framework assembly with the following signature:

public static bool EnableDecrementPriority(object sender, ScopeNode scopeNode, ActionDescription action, ResultObjectBase resultObject)

For more information about calling methods in a .NET Framework assembly, see Configuration Manager AssemblyType Action.

Security Permissions

You can restrict the availability of an action by applying security restrictions to the selected object or object class.

Object Instance Permissions

You can restrict the availability of an action by applying required permissions to the selected object. In the following XML example, the following elements specify the instance permissions for the selected object:

Element	Description
`InstancePermissions`	The parent element to the list of instance permissions.
`SecurityFlagsDetailDescription`	The security flags that must be set for the action to work.

In the following XML example, the Delete action for a selected object is available only if the user has modify permissions:

<ActionDescription ActionVerb="Delete" Class="Default" SelectionMode="Both" InstanceDependsOn="SMS_Site">  
<ShowOn> <string>DefaultContextualTab</string> <!-- Show on Ribbon -->    <string>ContextMenu</string> <!-- Show on Context Menu --></ShowOn><InstancePermissions><SecurityFlagsDetailDescription BitName="Modify" BitValue="2" DependsOn="1" /></InstancePermissions>  
</ActionDescription>

Object Class Permissions

You can use the ClassPermissions element to set the object class permissions required for an action. ActionSecurityDescription describes the object class and the required permissions for that object class. The following XML example describes the permissions required for SMS collections:

<ClassPermissions> <ActionSecurityDescription ClassObject="SMS_Collection" RequiredPermissions="1280" />  
</ClassPermissions>

Permission Values

The permission values for the RequiredPermissions attribute are the same as for the SecurityFlagsDetailDescription class and are as follows:

Permission	Values	Depends on
Read	1	None
Modify	2	1
Delete	4	1
Distribute	8	1
CreateChild	16	1
