ASP.NET 2.0 and data Access ASP.NET 2.0 provides us with improved data access modes, which reduces the amount of code required to perform data binding in ASP.NET 1.x. First, there is no need to program the implementation of an instance, setting attribute, and a method of calling the ADO object in the aforementioned list. What you need to do is simply adding a server-side control on the page and sets the properties. When presenting the page, ASP.NET 2.0 will automatically perform all object instantiations, and call methods to create and display data. Contrast the following ASP.NET 2.0 code with the above code:
demo </ title> </ head> <body> <form id = "form1" runat = "server"> <asp: SqlDataSource ID = "SqlDataSource1" Runat = "server" SelectCommand = "SELECT au_lname FROM authors WHERE (state = @state)" ConnectionString = "Server = HPSERV; Integrated Security = True; Database = pubs"> <SelectParameters> <asp: Parameter Type = "String" DefaultValue = "CA" Name = "state" /> </ SelectParameters> </ asp: SqlDataSource> <asp: BulletedList ID = "BulletedList1" runat = "server" DataSourceID = "SqlDataSource1" DATEXTFIELD = "AU_LNAME"> </ asp: bulletEDList> </ form> </ body> </ html> second improvement comes from server-side controls that are sensitive to events in page survival. ASP.NET 2.0 server-side control can make the correct action at the correct time. Note Any reference to events in the page survival in the ASP.NET 2.0 page. Students with early versions of ASP generally feel confused, especially data bindings. Therefore, many ASP.NET 1.x pages will have this to make programmers to write code, that is, call DATABIND in the wrong event, or call DataBind multiple times in multiple events. These timing operations can now be powered by server-side data controls from ASP.NET 2.0. Note that two server-side controls are used in the previous ASP.NET 2.0 code. The first is a data source control, and this example is a SqlDataSource control.</p></div><div class="text-center mt-3 text-grey">
