Default value of a column in a table is used by server only. There's no way you can get it on the client. Moreover, in your case it is senseless because you use default values defined as expressions, for example, "sysdate", or "sysdate+7". This values can not be correctly computed on the client. However, you can generate typed dataset and define the default values for client. For more information read in MSDN about typed datasets.
