    {
        strQuery += "and nvrbusinessunit ='" + ddlBusinessUnit.SelectedValue + "' ";
    }
    if (hdnDepartment.Value != "")
    {
        string strDepartment = hdnDepartment.Value;
        string[] strarrDepartment = strDepartment.Split(',');
        strDepartment = "";
        for (int i = 0; i < strarrDepartment.Length; i++)
        {
            strDepartment += "'" + strarrDepartment[i] + "'" + ",";
        }
        strDepartment = strDepartment.TrimEnd(',');
        strQuery += "and nvrdepartment in(" + strDepartment + ")";
    }

    populateDropDown(strQuery, ddlEmployeeName, "nvrempname", "nvrempcode");
}
