Simply you take the Last inserted code from your database.
Query : SELECT TOP 1 EmpCode FROM tblEmployee ORDER BY EmpId DESC

This will give you the latest Emp Code.

Now you may split the Code
int iEmpCodeNo = Convert.ToInt(EmpCode.Substring(1));

This will give you the EmpCodeNo. Now increment 1 with this and add the 'E'
string NewEmpCode = "E" + (iEmpCodeNo + 1).ToString();

This will give you the latest code. You may simply bind this in your text box.
