<SCRIPT runat="server">
private void Page_Load(object sender, EventArgs e) {
SqlDataSource aSqlDataSource = new SqlDataSource();
// Security Note: The SqlDataSource uses a QueryStringParameter,
// Security Note: which does not perform validation of input from the client.
QueryStringParameter qs1 =
new QueryStringParameter("QueryStringParam1","requestfield1");
aSqlDataSource.SelectParameters.Add(qs1);
QueryStringParameter qs3 =
new QueryStringParameter("QueryStringParam3","requestfield3");
aSqlDataSource.SelectParameters.Add(qs3);
// Insert
aSqlDataSource.SelectParameters.Insert(1, new QueryStringParameter("QueryStringParam2", "requestField2") );
// Iterate through the ParameterCollection and print out the
// names of the Parameters contained by it.
foreach (Parameter aParameter in aSqlDataSource.SelectParameters) {
Response.Write(aParameter.Name + "<BR>");
}
