Users may want to jump to a specific order if they
know the Order ID. This will cause a second BindingSource control to be created.
There are three main technologies that enable AJAX functionality: remote method
calls, client-side data binding, and visual effects. Writing an add-in using our
model is very easy: we employ a custom attribute that defines the add-in assembly
entry in its assembly and provides descriptive information about the add-in to the
host.
There are static methods in the entities to insert,
update, and delete data, too.
The first entity that returns true will be returned
and then used to reposition the BindingSource to its index. The following code
checks to see if new AddIns have been installed.
In this month's column, I examine ASP. Once the
attribute is applied, all the add-in has to do is implement the methods defined in
its abstract base class.
All the controls are bound to the same data source
via a BindingSource control.
The Straight Way to ASP.
The retrieval methods use
ADO.
