BeginSetScope Method

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

Sets the scope of the specified category.

Namespace:  Microsoft.Rtc.Collaboration.GroupChat.Management
Assembly:  Microsoft.Rtc.Collaboration.GroupChat (in Microsoft.Rtc.Collaboration.GroupChat.dll)

public IAsyncResult BeginSetScope(
	ChatRoomCategory category,
	ICollection<GroupChatPrincipalSummary> newScope,
	AsyncCallback userCallback,
	Object state


Type: Microsoft.Rtc.Collaboration.GroupChat.ChatRoomCategory
The category on which you wish to set scope.
Type: System.Collections.Generic.ICollection<GroupChatPrincipalSummary>
The new scope.
Type: System.AsyncCallback
The method to be invoked when this asynchronous operation completes.
Type: System.Object
An object to be passed back to the callback.

Return Value

Type: System.IAsyncResult
An IAsyncResult that references this operation.


Thrown when invalid arguments are passed.


Thrown when the GroupChatEndpoint is not established.


Thrown when the chat server connection is not in a valid state to send the command.


Thrown when the GroupChatEndpoint encounters an error communicating with the group chat server.

Unlike BeginAddUsersOrGroupsToRole(ChatRoomRole, Uri, ICollection<GroupChatPrincipalSummary>, AsyncCallback, Object), this command deletes the existing scope, and replaces it with the specified newScope.

This request will be processed asynchronously. See EndSetScope(IAsyncResult) to complete this asynchronous operation.

The scope of a category is a collection of users and user groups who may:

  • Search for and find the chat rooms in this category and those below it.

  • Be added to the member or manager list of the category, its subcategories, and chat rooms.

When specified, the scope of a category must always be a subset of the scope of the parent category. Hence, scope can be narrowed, but never increased. See BeginGetScope(Uri, AsyncCallback, Object)
