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.
