Parameters
- keys
An IDictionary of object or row keys to be updated by the update operation.
- values
An IDictionary of name/value pairs that represent data elements and their new values.
- oldValues
An IDictionary of name/value pairs that represent data elements and their original values.
- callback
A DataSourceViewOperationCallback delegate that is used to notify a data-bound control when the asynchronous operation is complete.
The Update method is the asynchronous data modification interface for all data source view objects. The Update method calls the ExecuteUpdate method using any keys, values, and oldValues parameter values supplied. The callback parameter is a delegate that a data-bound control passes to the data source view, which is used to notify the data-bound control when the ExecuteUpdate operation has completed. The method uses the parameters of the DataSourceViewOperationCallback delegate to return the number of affected records and any Exception exception that is thrown by the ExecuteUpdate call.
