Hi
Can you try to create your datatable as given below. (I didn't compile the code)

VB

Dim dt As New DataTable()
dt.Columns.Add(New DataColumn("RowNumber", GetType(String)))
dt.Columns.Add(New DataColumn("Col1", GetType(String)))
dt.Columns.Add(New DataColumn("Col2", GetType(String)))
dt.Columns.Add(New DataColumn("Col3", GetType(String)))
dt.Columns.Add(New DataColumn("Col4", GetType(String)))
dt.Columns.Add(New DataColumn("Col5", GetType(String)))
dt.Columns.Add(New DataColumn("Col6", GetType(String)))
dt.Columns.Add(New DataColumn("Col7", GetType(String)))
dt.Columns.Add(New DataColumn("Col8", GetType(String)))
dt.Columns.Add(New DataColumn("Col9", GetType(String)))


Dim oDr As DataRow = dt.NewRow()
dr("RowNumber") = 1
dr("Col1") = String.Empty
dr("Col2") = String.Empty
dr("Col3") = String.Empty
dr("Col4") = String.Empty
dr("Col5") = String.Empty
dr("Col6") = String.Empty
dr("Col7") = String.Empty
dr("Col8") = String.Empty
dr("Col9") = String.Empty
dt.Rows.Add(oDr)


oDr = Nothing
oDr = dt.NewRow()
dr("RowNumber") = 2
dr("Col1") = String.Empty
dr("Col2") = String.Empty
dr("Col3") = String.Empty
dr("Col4") = String.Empty
dr("Col5") = String.Empty
dr("Col6") = String.Empty
dr("Col7") = String.Empty
dr("Col8") = String.Empty
dr("Col9") = String.Empty
dt.Rows.Add(oDr)

oDr = Nothing
oDr = dt.NewRow()
dr("RowNumber") = 3
dr("Col1") = String.Empty
dr("Col2") = String.Empty
dr("Col3") = String.Empty
dr("Col4") = String.Empty
dr("Col5") = String.Empty
dr("Col6") = String.Empty
dr("Col7") = String.Empty
dr("Col8") = String.Empty
dr("Col9") = String.Empty
dt.Rows.Add(oDr)

'---3 rd row
'--4 th row
' --5 thw
'etc..create all your rows like this

dt.AcceptChanges()
grvBorang.DataSource = dt
grvBorang.DataBind()
