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

public virtual FormViewMode DefaultMode { get; set; }

Property Value

Type: System.Web.UI.WebControls.FormViewMode

One of the FormViewMode values. The default is FormViewMode.ReadOnly.

Exception Condition
ArgumentOutOfRangeException

The specified value is not one of the FormViewMode enumeration values.

Use the DefaultMode property to specify whether the FormView control returns to edit, insert, or read-only mode after an update, insert, or cancel operation is performed. By default, the FormView control returns to read-only mode; however, you can keep the FormView control in edit or insert mode by setting this property to the appropriate value. The following table lists the different mode values.

Mode

Description

FormViewMode.Edit

The FormView control is in edit mode, which allows the user to update the values of a record.

FormViewMode.Insert

The FormView control is in insert mode, which allows the user to add a new record to the data source.

FormViewMode.ReadOnly

The FormView control is in read-only mode, which is the normal display mode.

This property is commonly used when the FormView control has a single purpose, such as only to insert or edit records.

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