Hi Mylor:
You use a DataRow object to move through the rows of a table within the DataSet

Something like this, assuming ds is the variable that holds your DataSet

For each dr in ds.Tables(0).Rows
    ...do something with the datarow
Next

If you want to go to the top of the table, use

Dim dr as DataRow = ds.Tables(0).Rows(0)

I'm guessing you want to move from item to item in the dataset.  I've done this by binding data to textboxes and using the buttons listed in the code below.  Hope this helps.  Question is kind of vague so let us know what you think

Private Sub NavigationButtons_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFirst.Click, btnLast.Click, btnNext.Click, btnPrevious.Click
        Select Case sender.Name
            Case "btnFirst"
                isLoading = True
                bmbCategory.Position = 0
                isLoading = False
            Case "btnPrevious"
                isLoading = True
                bmbCategory.Position -= 1
                isLoading = False
            Case "btnNext"
                isLoading = True
                bmbCategory.Position += 1
                isLoading = False
            Case "btnLast"
                isLoading = True
                bmbCategory.Position = bmbCategory.Count - 1
                isLoading = False
        End Select
        DisplayPosition()
    End Sub
