Description
Controls how the provider locates records when applying updates.
Use UpdateMode to specify the criteria for locating a record in the dataset when applying updates. UpdateMode specifies whether modified records are located based on all columns (fields), on only the key fields, or on the key fields plus the original values of fields that have been modified.
Note: To control how the provider locates records by specifying individual fields, use the field components' ProviderFlags property.
