Assembly: System.Web (in System.Web.dll)
The FormViewModeEventArgs type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | FormViewModeEventArgs | Initializes a new instance of the FormViewModeEventArgs class. |
| Name | Description | |
|---|---|---|
![]() | Cancel | Gets or sets a value indicating whether the event should be canceled. (Inherited from CancelEventArgs.) |
![]() | CancelingEdit | Gets a value indicating whether the ModeChanging event was raised as a result of the user canceling an edit operation. |
![]() | NewMode | Gets or sets the mode to which the FormView control is changing. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The ModeChanging event is raised when a FormView control attempts to switch between edit, insert, and read-only mode, but before the mode actually changes. This allows you to provide an event-handling method that performs a custom routine, such as configuring the FormView control for a specific mode or canceling the mode change, whenever this event occurs.
A FormViewInsertEventArgs object is passed to the event-handling method, which allows you to determine the mode to which the FormView control is changing, to determine whether the ModeChanging event was raised as a result of the user canceling an edit or insert operation, or to indicate that the mode change should be canceled. To determine the new mode, use the NewMode property. You can also use the NewMode property to programmatically specify an alternate mode to which to change by setting it to one of the FormViewMode enumeration values. Use the CancelingEdit property to determine whether this event was raised as the result of the user canceling an edit or insert operation. To cancel the mode change, set the Cancel property to true.
For more information about handling events, see Consuming Events.
For a list of initial property values for an instance of the FormViewModeEventArgs class, see the FormViewModeEventArgs constructor.
The following example demonstrates how to use the FormViewModeEventArgs object passed to the event-handling method for the ModeChanging event to hide the pager row when the FormView control transitions to edit mode.
