ObjectDataSourceView::Updating Event

 

Occurs before an Update operation.

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

public:
event ObjectDataSourceMethodEventHandler^ Updating {
	void add(ObjectDataSourceMethodEventHandler^ value);
	void remove(ObjectDataSourceMethodEventHandler^ value);
}

Handle the Updating event to perform additional initialization operations that are specific to your application, to validate the values of parameters, or to change the parameter values before the ObjectDataSource control performs the Update operation. The parameters are available as an IDictionary collection, accessed by the InputParameters property, which is exposed by the ObjectDataSourceMethodEventArgs object.

For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates how to use a DropDownList control, TextBox controls, and several ObjectDataSource controls to update data. The DropDownList displays the name of a NorthwindEmployee, while the TextBox controls are used to enter and update address information. Because the UpdateParameters collection contains a ControlParameter object that is bound to the selected value of the DropDownList, the button that triggers the Update operation is enabled only after an employee is selected.
