DetailsViewUpdatedEventArgs.KeepInEditMode Property

Gets or sets a value indicating whether the DetailsView control should remain in edit mode after an update operation.

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

public bool KeepInEditMode { get; set; }

Property Value

Type: System.Boolean
true to remain in edit mode after an update operation; otherwise, false. The default is false.

By default, the DetailsView control returns to the mode specified by the DefaultMode property after an update operation. Use the KeepInEditMode property to specify whether the DetailsView control should remain in edit mode. To keep the DetailsView control in edit mode, set this property to true.

NoteNote:

This property should be used if you want to override the default mode at a specific occasion. If the DetailsView control needs to remain in edit mode by default, set the DefaultMode property instead.

The following code example demonstrates how to use the KeepInEditMode property to keep a DetailsView control in edit mode after an update operation.
