I have a task in hand that requires me to send a form to a client by email as soon as it is submited.
My question is: Having an aspx(in order to reuse my form) how can I get the generated html to send it by mail?
Thanks in advance
EDIT:
I know how to send emails, what I am looking for is how to get the html that is generated in my webform so i can place it in the email.
You should be able to call Render on it and stream it.
StringWriter stringWriter = new StringWriter();
HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
Page.RenderControl(htmlWriter);
string output = stringWriter.ToString();
Using the SmtpMail class in System.Web?

Is there any Possibility that it can Generate Compressed HTML from the GridVIew ???
I do not suggest to do that, but I can give an idea for how I will try to do that:
You can render the GridView in a string, make the compression and then show it to the page.
TextWriter stringWriter = new StringWriter();
HtmlTextWriter GrapseMesaMou = new HtmlTextWriter(stringWriter);
cGridView.RenderControl(GrapseMesaMou);
// this is the string that you show on page (eg place it on a literal)
string cFinalResults = CompressHtml(stringWriter.ToString());
// not show it any more...
cGridView.Visible = false;
one html compressor: http://code.google.com/p/htmlcompressor/
I do not know if this can work smoothly for all cases, but you can give it a try to see if it is what you look for.
I am using jquery ajax to call function from webservice.
In that function I am creating a pdf file using itextsharp tool.
I want that my pdf file created should open in browser when return.
can anyone help me what should be my return type for that
Below is the code I am using in webservice
public void GeneratePDf(string ID) {
string attachment = "attachment; filename=" + ID + ".pdf";
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.AddHeader("content-disposition", attachment);
HttpContext.Current.Response.ContentType = "application/pdf";
StringWriter stw = new StringWriter();
HtmlTextWriter htextw = new HtmlTextWriter(stw);
htextw.AddStyleAttribute("font-size", "12px");
htextw.AddStyleAttribute("color", "Black");
Page pg = new Page();
HtmlForm frm = new HtmlForm();
pg.EnableEventValidation = false;
pg.RenderControl(htextw);
Document document = new Document();
document = new Document(PageSize.A4, 10, 10, 0, 0);
PdfWriter.GetInstance(document, HttpContext.Current.Response.OutputStream);
document.Open();
Font verdana = FontFactory.GetFont("Verdana", 10, Font.BOLD, new CMYKColor(75, 68, 67, 90));
PdfPCell blank1 = new PdfPCell(new Phrase("Hello ", verdana));
document.Add(blank1);
//document.Add(tablegrid);
StringReader str = new StringReader(stw.ToString());
HTMLWorker htmlworker = new HTMLWorker(document);
htmlworker.Parse(str);
document.Close();
HttpContext.Current.Response.Write(document);
}
Can anyone tell me what I am doing wrong
The short answer is, "don't use AJAX for this", you are creating unnecessary complication. Instead, just make a normal GET/POST request via your browser. You can still use JavaScript if you want but the important part is that you have the browser make the request so that it can receive the response.
The long answer is...
Web servers respond to requests from web browsers and things happen just as you expect them to (usually). Web browsers have a list of content types that they are aware and use this list to sometimes parse the server's response and sometimes hand it off to a 3rd party application. Once you start messing around with AJAX and other similar technologies you break this model and are saying that you want to handle the processing instead of the browser. The browser will broker your request and the server's response but otherwise it won't do anything unless you tell it to. This works great for string-like things but gets much more complicated when you deal with binary data.
I am new to asp.net, I am trying to have a photo contest on my website.
I want users to upload their pictures on my site and I want to get an email with the picture attachment to my email ID.
How can I do this and is there a better way of doing this(I have to use asp for this)
Thanks,
jack
It should be relatively simple by using the FileUpload webcontrol on the aspx form and using System.Net.Mail.SmtpClient to send a MailMessage with an attachment.
Well if you wanna do it in vb you would do something like this :
Dim message As New Mail.MailMessage
Using message
message.To.Add(New Mail.MailAddress("notyou#gmail.com", "Name Reciever"))
message.From = New Mail.MailAddress("you#gmail.com", "Name Sender")
message.Subject = "subject!"
message.Body = "Text!"
message.Attachments.Add(New Mail.Attachment("pic.jpg"))
Using smtp As New Net.Mail.SmtpClient("Your smtp")
smtp.Send(message)
End Using
But you prob use c# but you din't say so ... but it prob looks alike anyhow ^^
I have a HTML page that I have created that essentially consists of:
<div>
<table>
<tr>
<td><asp:label runat="server" id="someText"></asp:label></td>
</tr>
</table>
</div>
The label text is generated on page load from an SQL query.
The above is a very basic and simplified version of what I have on my page.
What I'd like to achieve is to be able to e-mail the entirety of the rendered HTML page without having to build the page again in my code-behind to send it.
Is there a way of doing this?
Thanks in advance for any help.
Something like this maybe (haven't tested):
StringBuilder sb = new StringBuilder();
HtmlTextWriter hw = new HtmlTextWriter(new System.IO.StringWriter(sb));
this.Render(hw);
MailMessage message = new MailMessage();
message.IsBodyHtml = true;
message.Body = sb.ToString();
(new SmtpClient()).Send(message);
If you want to send the email as you render the page, without rerunning the page lifecycle, try the following.
Make a wrapper stream class that inherits Stream and contains two additional streams, and override its Write method to write to both streams. I don't think you need to override anything else except the Can_Whaterver_ properties, but I'm not sure.
Make a field in your Page class of type MemoryStream to hold a copy of the response.
Then, handle the page's PreInit event and set the Response.Filter, like this:
Response.Filter = new CopierStream(Response.Filter, responseCopy);
//`CopierStream` is the custom stream class; `responseCopy` is the MemoryStream
Finally, override the Page's Render method, and, after calling base.Render, you can send responseCopy by email using the SmtpClient class.
This is a very complicated technique that you should only do if you really don't want to re-run the page lifecycle.
Whichever way you do it, if your page has any images or hyperlinks, make sure that their urls include the domain name, or else they won't work in the email.
Use a webclient:
Dim wc As New WebClient
Dim str As String = wc.DownloadString("yoururl.com")
SendEmail(str) ' your email method '
I want to send emails in HTML format. How can I use asp.net to generate HTML content for emails.
Using output of .aspx page(Tried there was nothing in email body. Must be something in page that can't be used for email)
Using Webcontrol and get web control output and use it as email body.
Using custom http handler so can call handler to get email body.
Can you please suggest what would be the best solution?
Some guide or sample reference would be great if know one.
Thanks for all answers:
I am implementing code below:
string lcUrl = "http://localhost:50771/webform1.aspx";
// *** Establish the request
HttpWebRequest loHttp =
(HttpWebRequest)WebRequest.Create(lcUrl);
// *** Set properties
//loHttp.Timeout = 10000; // 10 secs
loHttp.UserAgent = "Code Web Client";
// *** Retrieve request info headers
HttpWebResponse loWebResponse = (HttpWebResponse)loHttp.GetResponse();
Encoding enc;
try
{
enc = Encoding.GetEncoding(loWebResponse.ContentEncoding);
}
catch
{
enc = Encoding.GetEncoding(1252);
}
StreamReader loResponseStream =
new StreamReader(loWebResponse.GetResponseStream(), enc);
string lcHtml = loResponseStream.ReadToEnd();
loWebResponse.Close();
loResponseStream.Close();
I think the ASPX file will make the most easy to edit mechanism. You can use
var stream = new MemoryStream();
var textWriter = new StreamWriter(stream);
Server.Execute("EmailGenerator.aspx", textWriter);
to capture the output of that page.
I personally don't like any of your options. I would probably do it by using an HTML file (or a template stored in a database) and substituting something like {{name}} with the appropriate parameter.
I did this, essentially we had a page that the user could view, and then they could click a button and send the html on the page in an email. Basically my page was responsible for generating the email. I did this by overriding the Render method, and providing my own stream or using the one passed to us. We did this dpeneding on if we were rendering what the user would see or emailing it.
protected override void Render(HtmlTextWriter writer)
{
if (_altPrintMethod)
{
System.Net.Mail.MailMessage....
mailMsg.Body=RenderHtml(baseUrl);
}
}
protected virtual string RenderHtml(string baseUrl)
{
RemapImageUrl(baseUrl);
StreamWriter sw = new StreamWriter(new MemoryStream());
HtmlTextWriter writer = new HtmlTextWriter(sw);
base.Render(writer);
writer.Flush();
StreamReader sr = new StreamReader(sw.BaseStream);
sr.BaseStream.Position = 0;
return sr.ReadToEnd();
}
One thing to note is you have to make sure all links are fully qualified. You might be able to use the base functionality. this is what I was doing in the RemapImageUrl basically I appended an absolute path on all my image files.
