I am working on the prototype for a scheduling application on an intranet system. The application is for scheduling and tracking promotional workers at various locations on various dates (hence location, date, workers dimensions).

Currently, only for prototyping, I am generating a data table of location/date, and from this I iteratively build an HTML table (asp:Table control). On visiting each cell, I query for people working that location-date and populate the cell accordingly. This is very inefficiant, and will at worst be improved by querying cached data for the whole location/date grid.

I'm looking around for established patterns and techniques for dealing with scenarios like this in HTML in general, maybe a visualisation library for jQuery or something, and for ASP.NET in particular, maybe a library for implementation on a GridView etc.

Am I going in the right direction with this, and if so, what recomendations are there regarding the previous paragraph?
