How would I filter a gridview based on a drop down list? I am not using object datasource or sql datasource.

'The dataset is generated based on the user's role
Me.gvRequests.DataSource = sr.GetRequests(CType(Session("Role"), Role))
Me.gvRequests.DataBind()

Public Function GetRequests(ByVal Role As Role) As DataSet
        Dim ad As New ActiveDirectory()
        Dim connection As New SqlConnection(ConnectionString())
        Dim sql As String = String.Empty
        Dim currentStatus As Integer = CInt(Status.Assigned)

        Select Case Role
            Case Role.MeManager
                sql = _
                        "SELECT DISTINCT TC_Requests.RequestNumber, " _
                      & "TC_Requests.RefNo, " _
                      & "TC_Requests.Originator, " _
                      & "TC_Requests.CreatedDate, " _
                      & "TC_Requests.CompletedDate, " _
                      & "(SELECT   TOP 1  Status " _
                      & "FROM TC_Routing " _
                      & "WHERE TC_Routing.RequestNumber = TC_Requests.RequestNumber " _
                      & "ORDER BY RoutingDate DESC) AS Status " _
                      & "FROM TC_Requests " _
                      & "INNER JOIN TC_Routing " _
                      & "ON TC_Requests.RequestNumber = TC_Routing.RequestNumber " _
                      & "ORDER BY TC_Requests.RequestNumber DESC"

            Case Role.ShopManager
                sql = _
                        "SELECT DISTINCT TC_Requests.RequestNumber, " _
                      & "TC_Requests.RefNo, " _
                      & "TC_Requests.Originator, " _
                      & "TC_Requests.CreatedDate, " _
                      & "TC_Requests.CompletedDate, " _
                      & "(SELECT   TOP 1  Status " _
                      & "FROM TC_Routing " _
                      & "WHERE TC_Routing.RequestNumber = TC_Requests.RequestNumber " _
                      & "ORDER BY RoutingDate DESC) AS Status " _
                      & "FROM TC_Requests " _
                      & "INNER JOIN TC_Routing " _
                      & "ON TC_Requests.RequestNumber = TC_Routing.RequestNumber " _
                      & "WHERE TC_Requests.Originator = '" & ad.GetNetworkLogon() & "' " _
                      & "ORDER BY TC_Requests.RequestNumber DESC"

            Case Role.MeEng
                sql = _
                        "SELECT DISTINCT TC_Requests.RequestNumber, " _
                      & "TC_Requests.RefNo, " _
                      & "TC_Requests.Originator, " _
                      & "TC_Requests.CreatedDate, " _
                      & "TC_Requests.CompletedDate, " _
                      & "(SELECT   TOP 1  Status " _
                      & "FROM TC_Routing " _
                      & "WHERE TC_Routing.RequestNumber = TC_Requests.RequestNumber " _
                      & "ORDER BY RoutingDate DESC) AS Status " _
                      & "FROM TC_Requests " _
                      & "INNER JOIN TC_Routing " _
                      & "ON TC_Requests.RequestNumber = TC_Routing.RequestNumber " _
                      & "WHERE TC_Routing.RoutedTo = '" & ad.GetNetworkLogon() & "' " _
                      & "AND TC_Routing.Status = " & currentStatus & " " _
                      & "ORDER BY TC_Requests.RequestNumber DESC"
        End Select

        Dim command As New SqlCommand(sql, connection)
        Dim da As New SqlDataAdapter(command)
        Dim ds As New DataSet

        Try
            da.Fill(ds, "dt_Requests")
            Return ds
        Catch ex As Exception
            Throw ex
        End Try

    End Function

You would do it by applying a RowFilter to a DataView based on your DataTable. Something like:

    Dim ds As DataSet = sr.GetRequests(CType(Session("Role"), Role))
    Dim dv As DataView = ds.Tables("dt_Requests").DefaultView
    dv.RowFilter = "YourColumn = '" & yourDropDown.SelectedText & "'"

    Me.gvRequests.DataSource = dv
    Me.gvRequests.DataBind()
