Especially for datetime and decimal field. I want the default value of the controls, which mapped to&nbsp;these fields is null string ("") during initialization&nbsp;of add&nbsp;new record screen. How can I customize the fields in business object mapper&nbsp;so that the default value can be null string?Thu, 13 Jul 2006 08:43:04 GMTWang Tong Yinhttp://forum.strataframe.net/FindPost1832.aspxWhen a new record it added, the business object automatically initializes the values within the new row to remove any DBNull.Value values.&nbsp; To prevent this, and allow all of the fields within the new row to be NULL, set the AllowNullValuesOnNewRow property on the business object to True.</P><P>If you only want a few fields to have NULL values, then in the SetDefaultValues event handler, add this code:</P><P>Me.CurrentRow("fieldname") = DBNull.Value</P><P>Add that for each field you want to initialize as a null value, and you'll be good to go.Thu, 13 Jul 2006 08:43:04 GMTStrataFrame Team
