following Exception occurs on using grid.rendercontrol(hw)

Control of type 'DataGridLinkButton' must be placed inside a form tag with runat=server.

i am working on a web application built in asp.net and vb.net framework 1.1
i need to export a grid to excel using a button click.code for button click is given below

the code snippet works fine for one web page but causes exception on the other.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Response.Clear()
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls")
Response.Charset = ""
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Dim tw As New System.IO.StringWriter
Dim hw As New System.Web.UI.HtmlTextWriter(tw)

HtmlTextWriter(stringWrite)
Grid.RenderControl(hw)-- exception caused here
Response.Write(tw.ToString())
Response.End()
End Sub

Not able to find where is the problem....Please help
