Using ADO.NET objects with Flash Remoting
Flash Remoting provides a service adapter for binding ADO.NET data tables and data views to
the Flash Remoting custom server control. To bind data sets to the custom server control, you use
the control's
DataSource
exposed as a RecordSet object.
The following C# example could be used in a code-behind file or in the ASPX page that contains
the Flash Remoting server control:
<%@ Page Language="c#" Debug="true" %>
<%@ Register TagPrefix="Macromedia" Namespace="FlashGateway"
Assembly="flashgateway" %>
<Macromedia:Flash id="Flash" Runat="Server" />
<%
// create a SQL connection object and open a connection
String source1 = "server=(local)\\NetSDK;" + "id=QSUser;pwd=QSPassword;" +
"database=Northwind";
sqlConnection = new SqlConnection(source1);
sqlConnection.Open();
// create the SQL statement
String selectCountry = "SELECT DISTINCT Country FROM Customers ORDER BY
Country ASC";
// query the database
SqlDataAdapter countryAdapter = new SqlDataAdapter(selectCountry,
sqlConnection);
// create a dataset object
DataSet countryData = new DataSet();
// fill the dataset with the query results
countryAdapter.Fill(countryData, "Customers");
// assign the dataset into the flash.datasource property
Flash.DataSource = countryData.Tables["Customers"];
// bind the datatable to the custom server control
Flash.DataBind();
// close the SQL connection
sqlConnection.Close();
