how to create an excel file???

Hello,
I have a asp.net web application which inside it I create a string with a table, which I want to be able to open an excel file with the data in that table.
my problem is that I am not able to open the excel in a new window(I do create the excel file. but it is being opend be the browser in the same page and not in a new page).
I use the following code:
Response.ContentType = "application/vnd.ms-excel";
Response.Write(ExcelString);
Response.End();

When ExcelString = “<TABLE borderColor=#808080 border=1>

Maybe you can try to use datagrid and do it as follow

Code:

---

Protected Sub but_export_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim now As DateTime = DateTime.Now
        Dim tmp As String = now.ToString("hh mm, MM dd, yyyy")
        xlfile = "Report_" + tmp + ".xls"
        Response.Clear()
        'Set the content type to Excel.
        Response.ContentType = "application/vnd.ms-excel"
        Response.AppendHeader("Content-disposition", "attachment; filename=" + xlfile)
        Response.Charset = ""
        ' Turn off the view state.
        Me.EnableViewState = False
       
        Dim tw As New System.IO.StringWriter()
        Dim hw As New System.Web.UI.HtmlTextWriter(tw)
       
        ' Get the HTML for the control.
        MemberDataGrid.RenderControl(hw)
        ' Write the HTML back to the browser.
        Response.Write(tw.ToString())
        ' End the response.
        Response.End()
   
    End Sub
