Opening PDF document inside Webform

1. Simply change the contenttype and open the PDF file

Response.Clear();
Response.ContentType = "application/pdf"; //change the content here based on different files type
Response.AddHeader("Content-Disposition", "inline;filename=" + strFilePath);
Response.WriteFile(strFilePath);
Response.End();

2. use Iframe Html control, set the src attribute of the control as PDF file and thats it..

Following is a ASP.net server control which uses the iframe,

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace PdfViewer
{
    [DefaultProperty("FilePath")]
    [ToolboxData("<{0}:ShowPdf runat=server></{0}:ShowPdf>")]
    public class ShowPdf : WebControl
    {
        #region "Declarations"

private string mFilePath;

#endregion
#region "Properties"

        [Category("Source File")]
        [Browsable(true)]
        [Description("Set path to source file.")]
        [Editor(typeof(System.Web.UI.Design.UrlEditor),
            typeof(System.Drawing.Design.UITypeEditor))]

        public string FilePath
        {
            get
            {
                return mFilePath;
            }

            set
            {
                if (value == string.Empty)
                {
                    mFilePath = string.Empty;
                }
                else
                {
                    int tilde = -1;
                    tilde = value.IndexOf('~');

                    if (tilde != -1)
                    {
                        mFilePath = value.Substring((tilde + 2))
                                         .Trim();
                    }
                    else
                    {
                        mFilePath = value;
                    }
                }
            }
        }   //end FilePath property

#endregion

#region "Rendering"

        protected override void RenderContents(HtmlTextWriter writer)
        {
            try
            {
                StringBuilder sb = new StringBuilder();

sb.Append("<iframe src="
+ FilePath.ToString() + " ");

                sb.Append("width=" +
                          Width.ToString() + " height=" +
                          Height.ToString() + " ");

sb.Append("<View PDF: <a href=" + FilePath.ToString() + "</a></p>");

sb.Append("</iframe>");

writer.RenderBeginTag(HtmlTextWriterTag.Div);

writer.Write(sb.ToString());

                writer.RenderEndTag();
            }
            catch
            {

                // with no properties set, this will render
                // "Display PDF Control" in
                // a box on the page

writer.RenderBeginTag(HtmlTextWriterTag.Div);

writer.Write("Display PDF Control");

writer.RenderEndTag();
} // end try-catch

//end RenderContents

#endregion

}
}
}

Refer the above control in WebPage :
<%@ Register TagPrefix="PDF" Namespace="PdfViewer" Assembly="<yourAssemblyname>" %>

# re: Opening PDF document inside Webform

Humm... interesting,

Great,so can we compile it and add it to the tool box instead of registering it in the page?

Anyway, thanks for the post 8/19/2009 9:47 AM | web development company
