Feature service UpdateAttachments method

Updates attachments from a layer.

EditResult[] DeleteAttachments(int LayerOrTableID, AttachmentData[] AttachmentDataArray, string VersionName, boolean RollbackOnFailure, boolean RollbackOnFailureSpecified)




ID of the layer or table in which to update attachments.


An array of AttachmentData objects to update.


Geodatabase version to apply the edits. This parameter applies only to feature services that expose geodatabases. If not specified, edits are applied to the published map's version.


RollbackOnFailure determines whether edits will be applied in a transactional manner. If set to true, and any of the edits fail, the entire edit operation will fail. If set to false, if some portion of the edits fail, they will not be applied. However, the edit operation will succeed and all others edits will be applied.

Not all data supports setting this parameter. Query the SupportsRollbackonFailureParameter property of the DataObjectTable to determine whether or not a layer supports setting this parameter. If SupportsRollbackonFailureParameter = false for a layer, then when editing this layer, RollbackOnFailure will always be true, regardless of how the parameter is set. However, if SupportsRollbackonFailureParameter = true, this means the RollbackOnFailure parameter can be set to true or false on edit operations.


Indicates if RollbackOnFailure is specified.

Return Value

This method returns an array of EditResult objects whose order is consistent with the order of the features or objects in the input AttachmentDataArray parameter. Each object has the ObjectID and GlobalID assigned to the feature or object upon adding it to the service. If adding of a feature or object fails (EditResult.Succeeded is false), the returned object will have the error code (EditResult.Code) and description (EditResult.Description).


Some AttachmentData properties, such as AttachmentID are not editable. If these properties are set, they will be ignored when applied to the service.
