LinqDataSource.EnableObjectTracking Property

Gets or sets the value that indicates whether changes to the data context object are tracked.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)
public bool EnableObjectTracking { get; set; }
<asp:LinqDataSource EnableObjectTracking="True|False" />

Property Value

Type: System.Boolean
true if the data context object is tracked for changes; otherwise, false. The default is true.

The EnableObjectTracking property is only used when selecting data from a LINQ To SQL data context object.

When you are interacting with read-only data, setting the EnableObjectTracking property to false improves performance because the data is not cached to determine if it has changed. However, it also disables deferred query execution. This property must be set to true if you want to use deferred query execution.
