Remarks
When a data source control that supports inserting is bound to a DetailsView control, the DetailsView control can take advantage of the data source control's capabilities and provide automatic inserting functionality.
Note
For a data source control to insert data, its SqlDataSource.InsertCommand property must be set with an insert query statement.
When the AutoGenerateInsertButton property is set to true, a CommandField row field with a New button is automatically displayed in the DetailsView control. Clicking the New button puts that DetailsView control in insert mode. When in insert mode, each bound field in the control that is not read-only displays the appropriate input control, such as a TextBox control, for the field's data type. This allows the user to enter the field's value for the new record.
When clicked, the New button is also replaced with an Insert button and a Cancel button. Clicking the Insert button inserts the new record in the data source and returns the control to the mode specified by the DefaultMode property. Clicking the Cancel button abandons the insert operation and returns the control to the default mode.
Note
To put a row in insert mode programmatically, use the ChangeMode method.
You can control the appearance of a record that is in insert mode by using the InsertRowStyle property. Common settings usually include a custom background color, foreground color, and font properties.
The DetailsView control provides several events that you can use to perform a custom action when a new record is inserted. The following table lists the available events.
| Event | Description |
|---|---|
| ItemInserted | Occurs when the Insert button is clicked, but after the DetailsView control inserts the record. This event is often used to check the results of the insert operation. |
| ItemInserting | Occurs when the Insert button is clicked, but before the DetailsView control inserts the record. This event is often used to cancel the insert operation. |
| ModeChanged | Occurs after the DetailsView control changes modes. |
| ModeChanging | Occurs before the DetailsView control changes modes. This event is often used to cancel the mode change. |
The value of AutoGenerateInsertButton is stored in view state.
