Asp objectdatasource onupdating
The Object Data Source control wraps a good deal of internal tasks, and its overall performance is slightly worse than classic binding.
So you might be happy to pay extra for quicker programming; but would you pay more to get less?
You can't do that with a Repeater control: it doesn't keep a copy of the objects to which it was bound.
The following 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.
Strongly Typed Data Source controls: You will find that just by typing Productivity Enabler When you select the Select Method Attribute, you will see via intellisense a list of all available methods from your domain. Simple Web Form Example: Here's an example of a simple webform in it's minimilist form, that would display a grid of all Employees with Auto-Generated columns.
Methods of such classes can be designated as methods for data-bound controls to execute common operations, such as select, delete, update, and insert.
Like other data source controls, Object Data Source supports declarative parameters to allow developers to pass page-level variables to the object s methods.
Such exception is probably aroused when ODS's do not match ODS Update Method's parameter.
When I finally resort to set the Update Method's parameter manually, everything works!
