Property Value

Type: System.String

A string that represents a format string applied to the names of any oldValues parameters passed to the Delete or Update methods. The default is "{0}".

The OldValuesParameterFormatString format string is applied to primary keys only, such as those that are identified by the DataKeyNames property of the data-bound control or in delete and update scenarios where the ConflictDetection property is set to the CompareAllValues value and a set of oldValues is passed to the corresponding data method. In this case, the format string is applied to each parameter name in the oldValues collection. For more information, see SqlDataSource.OldValuesParameterFormatString.

The value of the OldValuesParameterFormatString property is stored in view state.
