SqlWhereBuilder is a web control which provides a user interface for generating custom SQL WHERE clauses. The SqlWhereBuilder web control provides a friendly interface for a user to enter query conditions, which may be compiled upon postback into a SQL WHERE clause. As an ASP.NET server control wrapping a JavaScript library, user-interaction happens entirely client-side, while on the server, additional functionality such as XML-based configuration and integration with IDbCommand objects is implemented.
