     I need to build a comma separated string out of the quantity and the revisions
for instance, if qty2 = 2 on first line  and  1 on second line then the string will look like

b,b,a

because my table looks like

revision  |  qty
b                2
a                1


my code so far for gridview

 For Each dr2 In gridview2.Rows
                Dim revision2 As System.Web.UI.WebControls.Label = dr2.FindControl("lblrevision")
                Dim qty2 As System.Web.UI.WebControls.TextBox = dr2.FindControl("txtqty")
