To provide the best user experience and minimize code repetition, you will use dynamic data templates.You can easily integrate pre-built dynamic data templates into your existing site by installing a Nu Get package.These controls allow page developers to declaratively access and modify data without writing any code to perform the data access. ) Filtering Database Data with Parameters, an earlier installment in this article series, showed how to filter the data returned by ASP. In a nutshell, the data source controls can include parameterized queries whose parameter values are defined via parameter controls.This article is one in a series of articles on ASP.

NET offers a variety of parameter controls, including ones that use hard-coded values, ones that retrieve values from the querystring, and ones that retrieve values from session, and others.While the Control Parameter works well with most types of Web controls, it does not work as expected with the Check Box List control.The Control Parameter is designed to retrieve a single property value from the specified Web control, but the Check Box List control does not have a property that returns all of the values of its selected items in a form that the Check Box List control can use.This tutorial builds on the project created in the first part of the series.
