I have 2 blocks of code, if someone could help me put them together I would get the functionality I am looking for. The first block of code downloads a gridview to excel using the download dialog I am looking for: Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control) ' Verifies that the control is rendered End Sub

Private Sub ExportToExcel(ByVal filename As String, ByVal gv As GridView, ByVal numOfCol As Integer)
    Response.Clear()
    Response.Buffer = True
    Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", filename))
    Response.Charset = ""
    Response.ContentType = "application/vnd.ms-excel"
    Dim sw As New StringWriter()
    Dim hw As New HtmlTextWriter(sw)

    gv.AllowPaging = False
    gv.DataBind()

    'Change the Header Row back to white color 
    gv.HeaderRow.Style.Add("background-color", "#FFFFFF")

    For i As Integer = 0 To numOfCol - 1
        gv.HeaderRow.Cells(i).Style.Add("background-color", "blue")
        gv.HeaderRow.Cells(i).Style.Add("color", "#FFFFFF")

    Next

    For i As Integer = 0 To gv.Rows.Count - 1
        Dim row As GridViewRow = gv.Rows(i)

        'Change Color back to white 
        row.BackColor = System.Drawing.Color.White

        For j As Integer = 0 To numOfCol - 1
            row.Cells(j).Style.Add("text-align", "center")
        Next


        'Apply text style to each Row 
        row.Attributes.Add("class", "textmode")

        'Apply style to Individual Cells of Alternating Row 
        If i Mod 2 <> 0 Then

            For j As Integer = 0 To numOfCol - 1
                row.Cells(j).Style.Add("background-color", "#CCFFFF")
                row.Cells(j).Style.Add("text-align", "center")
                '#C2D69B
                'row.Cells(j).Style.Add("font-size", "12pt")
            Next

        End If
    Next
    gv.RenderControl(hw)

    'style to format numbers to string 
    Dim style As String = "<style> .textmode { mso-number-format:\@; } </style>"
    Response.Write(style)
    Response.Output.Write(sw.ToString())
    Response.Flush()
    Response.End()
End Sub

The second block of code is a sample report I am wish to be downloaded. So instead of downloading a gridview I want this function to accept a worksheet object.
