RemoveActivationExtension Method

In This Topic

Removes the extension id (guid) from being registered with the table. This method must be called on the Main CIM Thread. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public static void RemoveActivationExtension( 
   Table table,
   Guid extensionId
)

Public Shared Sub RemoveActivationExtension( _
   ByVal table As Table, _
   ByVal extensionId As Guid _
)

Parameters

table: The table from which the extension id will be removed
extensionId: The extension id (guid) to be unregistered

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.
System.ArgumentNullException	Value cannot be null: table
System.ArgumentException	extension id cannot be empty

Remarks

Removing an extension id (guid) from a table removes it from participating in whichever special behaviors were linked to the given id.
Any backward compatibility removed by the extension id will be restored (depending on what other Geodatabase functionality is currently enabled and may additionally be limiting backwards compatibility).
Activation extension ids are supported on registered classes in Enterprise, File, Mobile and on ArcObjects Feature Service geodatabases.
Calling RemoveActivationExtension when the table is being edited will fail.

Example

Table Extension Ids

public void ExtensionIds1(Table table)
{
  //Add an extension id to a table
  //Check documentation for restrictions on backward compatibility - backward
  //compatibility is limited to ArcGIS Pro 3.1 if an extension id is added.
  //Note: This is an extension method. It is for use in addins only and not CoreHost.
  string extension_id_string = "52d8f3be-b73d-4140-beaf-23d4f9b697ea";
  Guid extension_id = Guid.Parse(extension_id_string);

  //Note: Must be within the lambda of QueuedTask.Run(() => { ...

  //register the extension id with the relevant table
  table.AddActivationExtension(extension_id);

  //Remove an extension id from a table
  //Restores backward compatibility assuming no other compatibility limitations are
  //in place.
  //Note: This is an extension method. It is for use in addins only and not CoreHost.
  table.RemoveActivationExtension(extension_id);

  //Check if a given extension id  is registered with a particular table.
  //Note: This is an extension method. It is for use in addins only and not CoreHost.
  if (table.GetHasActivationExtension(extension_id))
  {
    //TODO - implement custom logic relevant to presence of extension_id
  }

  //Enumerate all extension ids on a given table.
  //Note: This is an extension method. It is for use in addins only and not CoreHost.
  foreach (Guid ext_id in table.GetActivationExtensions())
  {
    //TODO - logic based on extension ids
  }
}
