So, the method in the code behind page would look like something like this: However, decrypting the data using a templatefield tag posed another problem, extracting new values from the ‘Text Box1’ control.
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source. For more information about handling events, see NIB: Consuming Events.There you have access to the object via the Event Args. New Object or something like that You can cast this property into the corresponding type and make your changes. This allows you to provide an event handler that performs a custom routine, such as synchronizing the Details View control with another control, whenever this event occurs.Normally the details view control automatically detects whether to pass a null in the parameter.
Instead when setting the Update Parameters in the codebehind, the control will update the database with the parameter names entered.
This allows you to provide an event handler that performs a custom routine, such as canceling the update operation, whenever this event occurs.
A Details View Update Event Args object is passed to the event handler, which allows you to determine the index of the record being updated and to indicate that the update operation should be canceled.
For more information, see Validation Server Controls. The Details View control can automatically add a Command Field row field with an Edit, Delete, or New button by setting the Details View. Unlike the Delete button (which deletes the selected record immediately), when the Edit or New button is clicked, the Details View control goes into edit or insert mode, respectively.
Validation server controls are also provided to assess user input. Auto Generate Insert Button properties to true, respectively.
For example ‘@Parameter’, will be sent in the update to the record instead of null.
