Hi mostafasalama145,
You can use convert DIV to PDF without using iTextSharp in the following ways.
1. Using SelectPdf package.
2. Using html2canvas and pdfmake plugins of JavaScript.
--------------------------------------------------------------------------------
1. Using SelectPdf package.
HTML
<div id="divDetails" runat="server">
<h1 style="color:red;">Apple</h1>
<h3>Apple is Red.</h3>
</div>
<asp:Button ID="btnConvert" runat="server" Text="Convert" OnClick="OnConvert" />
Code
protected void OnConvert(object sender, EventArgs e)
{
//Fetch DIV content
string content = divDetails.InnerHtml;
HtmlToPdf convertToPDF = new HtmlToPdf();
PdfDocument pdfDoc = new PdfDocument();
//Converts HTML string to the PDF
pdfDoc = convertToPDF.ConvertHtmlString(content);
//Determine the BYTE array of Generated PDF
byte[] bytes = pdfDoc.Save();
//Read SMTP section from Web.Config.
SmtpSection smtpSection = (SmtpSection)ConfigurationManager.GetSection("system.net/mailSettings/smtp");
string host = smtpSection.Network.Host;
int port = smtpSection.Network.Port;
using (MimeMessage mm = new MimeMessage())
{
mm.From.Add(new MailboxAddress("Sender", "sender@gmail.com"));
mm.To.Add(new MailboxAddress("Recepient", "sender@gmail.com"));
mm.Subject = "Convert DIV to PDF using SelectPDF library";
BodyBuilder builder = new BodyBuilder()
{
TextBody = "The DIV is sucessfully converted to PDF using SelectPDF library."
};
//Adding PDF as attachment.
builder.Attachments.Add("Converted PDF.pdf", bytes);
mm.Body = builder.ToMessageBody();
using (SmtpClient smtp = new SmtpClient())
{
//Set to False to avoid Certificate verification.
smtp.CheckCertificateRevocation = false;
smtp.Connect(host, port, SecureSocketOptions.Auto);
smtp.Authenticate("sender@gmail.com", "<Password>");
smtp.Send(mm);
smtp.Disconnect(true);
}
}
ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Email sent.');", true);
}

2. Using html2canvas and pdfmake plugins of JavaScript
HTML
In this case, ScriptManager is used to enable Page method as Web Method will be called to send email.
<form runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
</asp:ScriptManager>
</form>
<div id="divDetails" runat="server">
<h1 style="color: red;">Apple</h1>
<h3>Apple is Red.</h3>
</div>
<input type="button" id="btnExport" value="Export" onclick="return Export()" />
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.2.7/pdfmake.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.min.js"></script>
<script type="text/javascript">
function Export() {
html2canvas(document.getElementById('divDetails'), {
onrendered: function (canvas) {
var data = canvas.toDataURL();
var docDefinition = {
content: [{
image: data,
width: 500
}]
};
//Creates PDF
var pdfDocGenerator = pdfMake.createPdf(docDefinition);
//Determine BASE64 string
pdfDocGenerator.getBase64(function (base64) {
SendByteArray(base64);
});
}
});
}
//Calls Server-Side Web Method
function SendByteArray(base64) {
PageMethods.SendEmail(base64, OnSuccess);
}
function OnSuccess(response) {
alert(response);
}
</script>
Code (Web Method)
[WebMethod]
public static string SendEmail(string bytes)
{
//Determine the BYTE array of Generated PDF
byte[] pdfByte = Convert.FromBase64String(bytes);
//Read SMTP section from Web.Config.
SmtpSection smtpSection = (SmtpSection)ConfigurationManager.GetSection("system.net/mailSettings/smtp");
string host = smtpSection.Network.Host;
int port = smtpSection.Network.Port;
using (MimeMessage mm = new MimeMessage())
{
mm.From.Add(new MailboxAddress("Sender", "sender@gmail.com"));
mm.To.Add(new MailboxAddress("Recepient", "sender@gmail.com"));
mm.Subject = "Convert DIV to PDF using html2canvas and pdfmake plugins";
BodyBuilder builder = new BodyBuilder()
{
TextBody = "The DIV is sucessfully converted using html2canvas and pdfmake plugins."
};
//Adding PDF as attachment.
builder.Attachments.Add("Converted PDF.pdf", pdfByte);
mm.Body = builder.ToMessageBody();
using (SmtpClient smtp = new SmtpClient())
{
//Set to False to avoid Certificate verification.
smtp.CheckCertificateRevocation = false;
smtp.Connect(host, port, SecureSocketOptions.Auto);
smtp.Authenticate("sender@gmail.com", "<Password>");
smtp.Send(mm);
smtp.Disconnect(true);
}
}
return "Email sent.";
}
