EntityDataSource.StoreOriginalValuesInViewState EntityDataSource.StoreOriginalValuesInViewState EntityDataSource.StoreOriginalValuesInViewState EntityDataSource.StoreOriginalValuesInViewState Property

Definition

Gets or sets a value that indicates whether the data from the data source should be stored in view state to make sure that the data has not been changed by another process before it is updated or deleted.

public:
 property bool StoreOriginalValuesInViewState { bool get(); void set(bool value); };
public bool StoreOriginalValuesInViewState { get; set; }
member this.StoreOriginalValuesInViewState : bool with get, set
Public Property StoreOriginalValuesInViewState As Boolean

Property Value

true if the values will be stored in view state; otherwise, false. The default value is true.

Remarks

To track changes when update and delete operations are enabled, the EntityDataSource control must store information about original values of loaded objects in the ControlState. Storing this required information in the view state will increase the page size. You can disable storing original values in the view state by setting the StoreOriginalValuesInViewState property to false. If you do this, the Entity Framework cannot track concurrency in updated objects. For more information, see Updating Data (EntityDataSource).
