Use following code snippet. create one function as below :

C#

public string NewEmpId()
{
        string strTempId, strMaxNum;
        strMaxNum = "2";    //Get this number from your database.using max(right(EmpId,4))
        if (strMaxNum == null || strMaxNum == "")
        {
            strMaxNum = "0";
        }
        strTempId = Convert.ToString(Convert.ToInt32(strMaxNum) + 1);
        if (strTempId.Length == 1)
        {
            strTempId = "000" + strTempId;
        }
        else if (strTempId.Length == 2)
        {
            strTempId = "00" + strTempId;
        }
        else if (strTempId.Length == 3)
        {
            strTempId = "0" + strTempId;
        }
        string strQuoteId = "EMP" + strTempId;
        return strQuoteId;
}

than call this function as below :

C#

string strNewEmpId = NewEmpId();
