VB

Protected Sub Btncalculate_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Btncalculate.Click
Call GetFinal()
End Sub

Public Sub GetFinal()
 For count As Integer = 0 To dtValue.Rows.Count - 1
Dim GrdView1 As New GridView()

'DataTable filling Code goes here

GrdView1.DataSource = dt1

AddHandler GrdView1.SelectedIndexChanged, AddressOf GrdView1_SelectedIndexChanged
AddHandler GrdView1.RowDataBound, AddressOf GrdView1_RowDataBound
AddHandler GrdView1.RowCommand, AddressOf GrdView1_RowCommand
GrdView1.DataBind()
end sub

Public Sub GrdView1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then

Just examine e.Row. Put a breakpoint and you should be able to see what it is.

Here's one option....

Create a dictionary object to store the names...

VB

' create a dictionary object to store header titles
Private headerNames As Dictionary(Of Int32, String) = Nothing

... and set the names when the RowType is Header. Then when you get to the DataRow you can use the cells index to pull the header name that was stored when the header row was databound.

VB

Protected Sub GridView1_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound

    If e.Row.RowType = DataControlRowType.Header Then
        ' initialize dictionary object when header is databound
        headerNames = New Dictionary(Of Int32, String)
        ' iterate header cells and capture each column's index and name and store in the dictionary object
        For i As Int32 = 0 To e.Row.Cells.Count - 1
            headerNames.Add(i, e.Row.Cells(i).Text)
        Next
    End If

    If e.Row.RowType = DataControlRowType.DataRow Then

        For i As Int32 = 0 To e.Row.Cells.Count - 1
            Dim cell As TableCell = e.Row.Cells(i)

            ' get header text from dictionary using column index
            Dim headText As String = headerNames(i).ToString()

            ' code to build link
            '

        Next

    End If

End Sub
