"multiple rows" If select all checked true ~ insert old data with updated dates appended to database for logging Mgr decision

I have been twirling this one around for days ~ HELP!! I hope that this will make since.

Here is the just of what I am doing in lang="VB" .

Dataset select satement generates a collection of data defined by login, that inturn says you are the manager of the following users

'Code example
Dim auth As String
auth = (Request.ServerVariables("AUTH_USER").Split("\")(1))
'in the select statement where manager = " & auth.ToString & "

Data is displayed with check boxs to select if the data displayed for the manager is correct
Note: Check boxes are databinded to a selected field ~ 1 is checked or 0 nothing ~ with postback true
DataBinder.Eval(Container.DataItem, "approved")

When the manager agrees that the data on the web page is correct
They will have two chooses either

press the Select All button or Checkbox next to the users approve and the uncheck disagree with the data

Finally have all insert new updated dates, plus answer and the manager whom made this decision

I can do one at a time by clicking the edit and then the options of update and or cancel; this could drive someone nuts doing 15 or more. This is why I need help to select all to have multiple rows inserted with changes
