IDataSourceFieldSchema.Identity Property

Definition

Namespace:

System.Web.UI.Design

Assembly:

System.Design.dll

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

public:
 property bool Identity { bool get(); };

public bool Identity { get; }

member this.Identity : bool

Public ReadOnly Property Identity As Boolean

Property Value

Boolean

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

Remarks

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.
