.NET Framework version 2.0

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

Member Name	Description
Edit	An editing mode that allows the user to update the values of an existing record
Insert	An inserting mode that allows the user to enter the values for a new record.
ReadOnly	A 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 ReadOnly 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 Edit.

<asp:formview id = "EmployeeFormView"
   datasourceid = "EmployeeSource"
   allowpaging
   datakeynames = "EmployeeID"
   defaultmode = "Edit"
   emptydatatext = "No employees found."
   runat = "server">
