Gets the current data-entry mode of the FormView control.
Assembly: System.Web (in System.Web.dll)
Use the property to determine whether the FormView control is in edit, insert, or read-only mode. The following table lists the different mode values.
The FormView control is in edit mode, which allows the user to update the values of a record.
The FormView control is in insert mode, which allows the user to add a new record to the data source.
The FormView control is in read-only mode, which is the normal display mode.
This value is normally set automatically by the FormView control when the New, Update, Insert, Delete, or Cancel command button is clicked. When the FormView control changes modes in response to an action, the events in the following table are raised. This allows you to create a custom event handler that performs the appropriate routine when the event occurs.
Occurs when the FormView control changes modes, but before the mode changes. This event is commonly used to cancel the mode change.
Note These events are not raised when you change the mode programmatically by using the ChangeMode method.
The following example demonstrates how to use the property to determine whether the FormView control is in edit, insert, or read-only mode. If the user attempts to navigate to another record while the FormView control is in edit more, the paging operation is canceled.
