I need to update entity row with many columns on it.
Can't we modify directly or simple method to update the row.

What I have tried:

C#

public static GlobalMessage ModifyCMEmailType(CMEmailType cMEmailType)
        {
            if (cMEmailType != null)
            {
                try
                {
                    var e = Db.CMEmailTypes.Where(p => p.CMEmailTypeId == cMEmailType.CMEmailTypeId).SingleOrDefault();
                    e.EmailType = cMEmailType.EmailType;
..
..

                    Db.SaveChanges();
                    return new GlobalMessage("", GlobalEnum.MessageStatus.Success, GlobalEnum.MessageCss.Success);
                }
                catch (Exception ex)
                {
                    ErrorWriter.WriteError(ex, "FunctionName --> InsertTable", "");
                }
            }
            return new GlobalMessage("", GlobalEnum.MessageStatus.Error, GlobalEnum.MessageCss.Error);
        }

C#

Now it depends on if you want to update entire row or what. Usually we assign properties like you are doing but we can also assign whole object to fetched object like
              e = cMEmailType;
but do need to update the ID again.
