ApplyAction Enumeration
Specifies the options for processing a row when the row cannot be applied during synchronization.
Namespace: Microsoft.Synchronization.Data
Assembly: Microsoft.Synchronization.Data (in microsoft.synchronization.data.dll)

Public Enumeration ApplyAction
public enum ApplyAction

public enum ApplyAction
Members
| Member name | Description |
|---|---|
| Continue | Continue processing, and add the row to the list of conflicts that are defined in SyncConflict. This is the default behavior. |
| RetryApplyingRow | Try to apply the row one more time. |
| RetryWithForceWrite | Force the row to be applied. |
Remarks
If a row cannot be applied during synchronization, the ApplyChangeFailed event is raised. The ApplyChangeFailedEventArgs object provides information about the error or conflict that caused the failure. In a handler for the event, you can specify whether the synchronization provider should try to apply the row again. Force writing changes on the client is handled by the client synchronization provider. Force writing changes on the server requires logic in the code that applies changes to the server. For more information, see How to: Handle Data Conflicts and Errors.
Example
The following code example specifies a value of RetryWithForceWrite for client-update/server-delete conflicts. To view this code in the context of a complete example, see How to: Handle Data Conflicts and Errors.
if (e.Conflict.ConflictType == ConflictType.ClientUpdateServerDelete)
{
//For client-update/server-delete conflicts, we force the client
//change to be applied at the server. The stored procedure specified for
//customerSyncAdapter.UpdateCommand accepts the @sync_force_write parameter
//and includes logic to handle this case.
Console.WriteLine(String.Empty);
Console.WriteLine("***********************************");
Console.WriteLine("A client update / server delete conflict was detected.");
e.Action = ApplyAction.RetryWithForceWrite;
Console.WriteLine("The client change was retried at the server with RetryWithForceWrite.");
Console.WriteLine("***********************************");
Console.WriteLine(String.Empty);
}
If e.Conflict.ConflictType = ConflictType.ClientUpdateServerDelete Then
'For client-update/server-delete conflicts, we force the client
'change to be applied at the server. The stored procedure specified for
'customerSyncAdapter.UpdateCommand accepts the @sync_force_write parameter
'and includes logic to handle this case.
Console.WriteLine(String.Empty)
Console.WriteLine("***********************************")
Console.WriteLine("A client update / server delete conflict was detected.")
e.Action = ApplyAction.RetryWithForceWrite
Console.WriteLine("The client change was retried at the server with RetryWithForceWrite.")
Console.WriteLine("***********************************")
Console.WriteLine(String.Empty)
End If
