FormViewMode Enumeration

Represents the different data-entry modes of a FormView control.

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

type FormViewMode

Member nameDescription
EditAn editing mode that allows the user to update the values of an existing record.
InsertAn inserting mode that allows the user to enter the values for a new record.
ReadOnlyA display mode that prevents the user from modifying the values of a record.

The FormViewMode enumeration is used to represent the data-entry modes of a FormView control. To determine the current mode of the control, use the CurrentMode property. After an insert or update operation, the FormView control returns to the mode specified by the DefaultMode property. By default, the control returns to read-only mode. You can specify an alternate mode to return to by setting the DefaultMode property. To change modes programmatically, use the ChangeMode method. When the FormView control changes modes, the events in the following table are raised.

Event

Description

ModeChanging

Occurs when a FormView control attempts to change between edit, insert, and read-only mode, but before the mode actually changes. This event is often used to cancel a mode change.

ModeChanged

Occurs after a FormView control has changed from edit, insert, or read-only mode to another mode. This event is often used to perform a task when the FormView control changes modes.

The following example demonstrates how to keep the FormView control in edit mode after an update operation by setting the DefaultMode property to FormViewMode.Edit.

Security noteSecurity Note

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
