I'm hoping in two months. Will start a new chapter this weekend that discusses all the methods for opening a new report in .NET.

Please also include how to handle the map dynamically from asp.net.

Opening map through CR desktop will have handle for displaying the map.
There is a navigator window to select, size, browse, zoom in-out the map.

How can we do that using ASP.NET?
