Actually what is problem is I am having two or three null records in my table. If I give a sql query in my program its resulting null record first. So remaining records are not resulting and I am getting error message like:
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlTypes.SqlNullValueException: Data is Null. This method or property cannot be called on Null values.
How can I resolve this issue??
