so what's your exact problem? Please don't paste code and expect us to guess your problem. Are you getting any errors?

This is just a code dump, not a question.

Add an '@' character to empid in the main string:

SQL

string str = "UPDATE EMPDETAILS SET NAME=@name,DEPT=@dept,CITY=@city WHERE chkstatus=@chkstatus AND EMPID=empid";

Becomes

SQL

string str = "UPDATE EMPDETAILS SET NAME=@name,DEPT=@dept,CITY=@city WHERE chkstatus=@chkstatus AND EMPID=@empid";

That way it matches the paramater name

However, I can see one simple glitch in your code and so I m putting it in the solution box here. The "empid" in your update statement is not parameterised by the "@" symbol

C#

string str = "UPDATE EMPDETAILS SET NAME=@name,DEPT=@dept,CITY=@city WHERE chkstatus=@chkstatus AND EMPID=@empid";

I am not sure if this is what you wanted but this is atleast one problem that i spotted in your code. For anything else you've got to tell us so.
