Update(); ...doesn't update the value :(I still haven't figured this out.The following code example demonstrates how to display data that is retrieved from a SQL Server database in a Drop Down List control and update the record using a Text Box control.For more information, see Script Exploits Overview (Visual Studio). The first code example demonstrates how to use a Sql Data Source control to display data in a Drop Down List control and update data when the Submit button is clicked.The second code example demonstrates how to display data that is retrieved from a Microsoft SQL Server database in a Drop Down List control and update the record using a Text Box control.An Overview of Inserting, Updating, and Deleting examined using the Object Data Source to facilitate inserting, updating, and deleting with the Grid View, Details View, and Form View controls.Alternatively, the Sql Data Source can be used in place of the Object Data Source.
These data modification capabilities can be plugged directly into a data source control without a line of code needing to be written.In previous tutorials we learned how the Object Data Source control allowed for inserting, updating, and deleting of data.The Sql Data Source control supports the same operations, but the approach is different, and this tutorial shows how to configure the Sql Data Source to insert, update, and delete data.Before the Update operation is performed, the On Updating method is called to raise the Updating event.
You can handle this event to examine the values of the parameters and to perform any preprocessing before an Update operation.
Raising an event invokes the event handler through a delegate. The On Updating method also allows derived classes to handle the event without attaching a delegate.
