Dear All, I just wondering how Codeproject.com prohibits non-registered users downloading any zip files attached in articles. For example, when I sign in and try to download any zip files attached in articles, I am able to download it. However, when I sign out and try to download any zip files simply I can not download. In both cases, the actual path of zip file seems transparent to user. How may I implement this feature (keeping download url transparent to user but prohibiting non-registered users to download) in my personal website? Any sort of suggestions, references, examples or articles are greatly appreciated. Sincerely Yours,

Hello, if your DataGrid name is dgGrid then try the following code System.IO.StringWriter tw = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw); DataGrid dgGrid = new DataGrid(); dgGrid.DataSource = dsExport; // Get the HTML for the control. dgGrid.HeaderStyle.Font.Bold = true; dgGrid.DataBind(); dgGrid.RenderControl(hw); // Write the HTML back to the browser. Response.ContentType = "application/vnd.ms-excel"; this.EnableViewState = false; Response.Write(tw.ToString()); Response.End();

Hi Magi, You have to send only dll and aspx files. Open Project->Copy Project from your IDE. From "Web Access Method:" Select "Front Page" and from "Copy:" select "only files needed to run this application" option.
