<H1>QueryString parameter binding demo</H1>
<P>Using the WebParameter attribute, the <STRONG>FirstName</STRONG> and <STRONG>CustomerID</STRONG>
fields in the underlying page class are 'bound' to <STRONG>txtFirstName</STRONG>
and <STRONG>txtCustomerID</STRONG> in the querystring. Additionally the
property <STRONG>LastName</STRONG> is bound to <STRONG>txtLast_Name</STRONG> in
the querystring.</P>
<P>In Page_Load the fields/properties are loaded from the querystring,
and the two fields values and the property value are
assigned to the controls.

<P>I should stress that this <EM>isn't</EM> advocating an alternative mechanism for
loading data into controls after postback - this rather contrived demo is
purely to demonstrate that the concept works. A far more common use would
be to handle a (non postback) query request like (for example):</P>
<P>http://somesite/showAccounts.aspx?accountBalanceMin=120&StartDate=2003/01/01&EndDate=2004/01/01</P>
