From: Ray Porter on 1 Sep 2010 07:04 Is there a way to set the value for a column in code when a ViewGrid row is edited? I have a row-last-updated date that is a required audit field in all our systems (required by data management). I don't really want the user updating this field as it should always be system controlled. If I create an editable ViewGrid tied to either an SqlDataSource or an ObjectDataSource, the field seems to only be updatable by the user. I can set it the first time by setting the DefaultValue in code but that has no effect after there is an initial value in the column. Do I need to completely take over the editing of the data in code?

From: SAL on 1 Sep 2010 12:42 You could create a business class that your ObjectDataSource is tied to with an update method and set the date in that Update method. Example: in this example, I'd have a TasksTable adapter defined in the Requests dataset and TasksRow would be a member of that dataset. <System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Update, False)> _ Public Function Update(ByVal dr As RequestDS.TasksRow) As Boolean dr.mYDate = Now() Dim b As Boolean Try Adapter.Update(dr) b = True Catch ex As Exception b = False End Try Return b End Function "Ray Porter" <ray_porter(a)unc.edu> wrote in message news:uXb1xVcSLHA.620(a)TK2MSFTNGP06.phx.gbl... > Is there a way to set the value for a column in code when a ViewGrid row > is edited?

Thanks. I'll look into that option.
