    • AND
     
    Here is MY Code Behind On Button Click Event
    1. protected void lnkPrintPDF_Click(Object sender, EventArgs e)  
    2. {  
    3. Response.Clear();  
    4. Response.Buffer = true;  
    5. Response.ClearContent();  
    6. Response.ClearHeaders();  
    7. Response.Charset = "";  
    8. string FileName = "Tally Certificate" + DateTime.Now + ".pdf";  
    9. StringWriter sw = new StringWriter();  
    10. HtmlTextWriter hw = new HtmlTextWriter(sw);  
    11. Response.Cache.SetCacheability(HttpCacheability.NoCache);  
    12. Response.ContentType = "application/pdf";  
    13. Response.AddHeader("Content-Disposition", "attachment;filename=" + FileName);  
    14. pnlCertificate.Visible = true;  
    15. pnlCertificate.RenderControl(hw);  
    16. Response.Write(sw.ToString());  
    17. Response.End();  
    18. }  
    So in this Button Click I am downlaod the file but when i open that pdf file i am getting error like Adobe Reader Can not open the file because it is either not a supported file type or because the file has been damaged. So, Please anyone tell me the solution.
