Displaying a progress bar for each row in a report or displaying a traffic light type status indicator for each row in SQL Server Reporting Services (SSRS) is not possible directly because SSRS just provide you a set of very basic report items like Line, Image etc.
But since Microsoft always design products with extensibility in mind, so we have a solution here which is Custom Report Item or CRI.
Custom Report Items are there to provide you a framework in .NET which you can use to implement your own graphical controls to display your data in your own way. These controls can be used to do virtually anything under .NET framework.
Following are some excellent resources to start with:
