I'm not 100% sure what your asking, my first guess is that you want to put the results of a query that queries two tables into your gridview? i.e. Get advTitle from another table into your grid?

You need to join the two tables in your select query then use a dataadaptor to fill a dataset with the query result. You will then be able to retieve the Result set as a single datatable:

'I'll assume your using a SQL database
dim DA as sqldataadapter
dim DS as new dataset
dim DT as Datatable
dim cmd as sqlcommand
dim conn as new sqlconnection ("Your connection String")
dim sSQL as string
dim advidid as integer  'You'll populate this with the correctID 

'Now formulate your SQL query I don't see what your first table was called - I'll use tblJobApp
sSQL = "SELECT tblJobApp.userID, tblJobApp.advid, tblJobAdv.Title, tblJobApp.Remarks" & _ 
"FROM tblJobApp INNER JOIN tblJobAdv ON (tblJobApp.advidid = tblJobAdv.advidid) " & _ 
"WHERE (tblJobAdv.advidid =" &avidid &")"

If conn.state <> connectionstate.Open then
end if

cmd = new sqlcommand
cmd.CommandType = Commandtype.text
cmd.CommandText = sSQL
cmd.Connection = conn

DA = New SqlDataAdapter
DA.SelectCommand = cmd
DT = DS.Tables(0)

MyGrid.Datasource = DT
MyGrid.Columns(1).Visible = false 'will hide the avidid form the users

If you need help with joking SQL tabes, provide us with the table names ad their fields.
