What does this mean?
code.....
' Set up our connection.
Dim objConnection As SqlConnection
objConnection = New SqlConnection("Server=loca
objConnection.Open()
'Specify the SQL string
Dim strSQL As String = "Select First_Name,Last_Name from USERS_TBL WHERE ID=" & strUserID2 & ""
'Create a command object
Dim objCommand As SqlCommand
objCommand = New SqlCommand(strSQL, objConnection)
objCommand.ExecuteNonQuery
'Get a datareader
objDataReader = objCommand.ExecuteReader(C
'Do the DataBinding
dgResults.DataSource = objDataReader
dgResults.DataBind()
getFirst = objDataReader("FIRST_NAME"
getlast = objDataReader("LAST_NAME")
getuserinfo = getlast & "," & getFirst
' Close the datareader/db connection

Try this instead of the DataReader:
Dim adapter As SqlDataAdapter = new SqlDataAdapter()
adapter.TableMappings.Add("Table", "USERS_TBL")
adapter.SelectCommand = cmdSuppliers
Dim ds As DataSet = New DataSet("Users")
adapter.Fill(ds)
dgResults.DataSource = ds
dgResults.DataBind()
