Hi Experts,

my .aspx code is attached

and the code in page load event is

Dim dt As New DataTable("sales")
dt.Columns.Add("ItemCode", GetType(String))
dt.Columns.Add("ItemName", GetType(String))
dt.Columns.Add("Quantity", GetType(Double))
dt.Columns.Add("Price", GetType(Double))
dt.Columns.Add("TaxCode", GetType(String))
dt.Columns.Add("Discount", GetType(Double))
dt.Columns.Add("LineTotal", GetType(Double))
Dim dr As DataRow
dr = dt.NewRow
dr("ItemCode") = ""
dr("ItemName") = ""
dr("Quantity") = 0.0
dr("Price") = 0.0
dr("TaxCode") = ""
dr("Discount") = 0.0
dr("LineTotal") = 0.0
dt.Rows.Add(dr)
ViewState("sales") = dt
GridView1.DataSource = dt
GridView1.DataBind()


Any Help Would be greatly appreciated
