ASPNET – Telecharger un fichier depuis un gridview

Bonjour

Ci-dessous un exemple (bouton BT_TELECHARGER )

protected void BT_TELECHARGER_Click(object sender, EventArgs e)
 {
 Response.Clear();

Response.AddHeader("content-disposition", "attachment; filename = "+ DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")+"View_AppelAstreinte.xls");
 
 Response.ContentType = "application/vnd.xls";

System.IO.StringWriter stringWrite = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter htmlWrite =
 new HtmlTextWriter(stringWrite);

DATA_VIEW.RenderControl(htmlWrite);

Response.Write(stringWrite.ToString());

Response.End();

}


 public override void VerifyRenderingInServerForm(Control control)
 {
 /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
 server control at run time. */
 }
