Quick and easy transfer of SQL Server table to Excel in VB.Net

We have a nice ASP web page with a grid-view into the data.

Now we want the ability to fetch that data in an Excel file.

A config setting does not allow OPENROWSET in a stored procedure, and that setting must be left for "security reasons."

I can make a datasource to Excel and copy fieds in a lopp, but surely there's a simple way in VB.Net to do the equivalent of
INSERT INTO ExcelDS.something

If you can't read my typos, that's "copy fields in a loop"
(actually two loops nested)

well how much data are you talking about??

"how much data"

It varies.  one to twelve pages of up to twenty lines each.

Speed is likely not a problem.  But if it can be done in a single call instead of two nested loops, ....

This kind of thing?

    Sub DatagridToExcel(ByVal dg As DataGrid, ByVal filename As String)
        ' Set the content type to Excel.
        Response.ContentType = "application/vnd.ms-excel"
        ' Remove the charset from the Content-Type header.
        Response.Charset = ""
        Response.AddHeader("Content-Disposition", "inline;filename=" & filename & ".xls")
        ' 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.
        ' Write the HTML back to the browser.
        ' End the response.
    End Sub

I've used the same method that Bob the Builder mentions.  Works pretty well.  The browsers handles most of the work for you... the user will get prompted to open the file in Excel.  They can then save it or do whatever they want.

That method requires the datagrid to not have paging, sort, etc. controls.

I was hoping for something (which might even work; I'll try it after the meeting I have to run to) like


Excel_DS.Tables("tablename") = SQL_DS.Tables("tablename")
