IDataSourceFieldSchema::Identity Property

Gets a value indicating whether the value of the field automatically increments for each new row.

Namespace:  System.Web.UI.Design
Assembly:  System.Design (in System.Design.dll)

property bool Identity {
	bool get ();
}

Property Value

Type: System::Boolean
true if the field's DataType is numeric and the underlying field increments automatically as new rows are added; otherwise, false.

For a DataColumn object, the Identity property corresponds to the AutoIncrement property. In SQL Server, an Identity column is a numerical column that automatically increments with each added record, thereby ensuring that the value uniquely identifies that record.
