FormViewInsertedEventArgs.KeepInInsertMode Property

Gets or sets a value indicating whether the FormView control should remain in insert mode after an insert operation.

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

public bool KeepInInsertMode { get; set; }

Property Value

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

By default, the FormView control returns to the mode specified by the DefaultMode property. Use the KeepInInsertMode property to specify whether the FormView control should remain in insert mode after an insert operation. To keep the FormView control in insert mode, set this property to true.

NoteNote:

This property should be used only when a situation occurs (such as an exception being raised) that requires the control to behave differently than it normally would. If the FormView control needs to remain in insert mode by default, set the DefaultMode property instead.

The following example demonstrates how to use the KeepInInsertMode property to keep the FormView control in insert mode when an exception occurs during an insert operation.
