I am using ASP.NET 1.1 Version.
I have two asp:dropdownlists named BooksTotalList and BooksSelectedList.
Now at the click of asp:button, I want to read the BooksSelectedList dropdownlist and do the processing.
When I try to read it gives me the following error
System.NullReferenceException: Object reference not set to instance of an object.
Please let me know how to solve this.
