Can anyone help know how to implement transaction in asp .net? Just like the database transaction, can we put some lines of code in a transaction ...for example
begin transaction
{
myMethodToSendMail() //sends email
myMethodToWrite() //Writes into an file e.g. xml file
myMethodToDB() //updates database
}
commit
Is there any way to achieve the above situation via asp .net using c#? I dont think the class SqlTransaction is the one to use......can anyone help...thanks in advance

No. No one knows how to do that. And if someone did know it certainly would not be Microsoft and they certainly would NOT document it[^].
Good luck, you're going to need it.

I am not sure that there is support for such a thing, except that you can send the mail last, and then undo the other steps, if one fails.

First, a definition of context. I'm working with user controls, which utilize the .ascx markup with the codebehind pointing to the .cs, basically the same model as a page. This is not the same as custom server controls, which are precompiled and generate the html output by hand. I have a significant number of user controls which display grids and other non trivial forms of output.
What I'm looking to do is build snippets of script code that people can copy & paste into their own web site, thus displaying the data that I feed them through the script. An example of this might be:
<script src="http://www.website.com/ShowList.aspx"></script>
the result of which would be displaying the grid view on the site who pasted this script into their page. This is a fairly common technique for javascript output. If I wanted to print "Hello, World!" on your web page, in the Page_Load of ShowList.aspx I could do something like this:
<br />
Response.Write("document.write('Hello World!');");<br />
By pasting the above script onto your page, Hello, World! magically appears. So far, so good. If I wanted to output something more complex, like a table, I could update the output to instead call document.getElementById() of some predefined div and then set the element's innerHTML to the HTML of the table, etc. Then the table would appear on your page, as if by magic. Again, no problem to do.
Now we get to the fun part. I don't want to reinvent the wheel and code the logic of dozens of controls all over again, using this model, so that I can use them as output in the aforementioned scripting scenario. What I really want to do is effectively hook into the output of the user control and redirect that output for use by the script. Here's a pseudo code idea of what I mean:
- Page_Load of ShowList.aspx spits out opening javascript, i.e. document.getElementById() our div
- UserControlOne.ascx outputs a grid control, we redirect the final html output of this grid to a routine in ShowList
- This routine takes the html and assigns it to the innerHTML of the element we found in step 1
- We now bask in the glory of our grid being automagically output to the user of the one line of script code
As you can see, where the rubber meets the road is hooking the html output of our user control so that we can redirect it to the output stream being formatted as javascript, and that's the part I'm having difficulty with. In the old C++ / MFC days, it was an ongoing business of finding out where you needed to hook something, hacking your way into it and redirecting it to where you wanted it to go. The fact that you had the full MFC code that you could step through in your debugger helped immensely, of course.
Unfortunatly, my knowledge of the ASP.NET architecture isn't yet that deep, and so I'm struggling trying to figure out how to hook the output of a user control and point it where I want it to go, i.e. the example above.
Apologies for the long explanation, but I asked this question last week and got little response because I really didn't ask the question very well. Hopefully this will give the knowledgable among you sufficient information about what I'm trying to accomplish that you can point me in the right direction.
And of course, any help would be most gratefully accepted!

Hi man Thanks for your reply,
I thought VS do it for you, i have checked the Sorce that VS generate when dropping the control into the form and it look like this
<asp:Calendar ID="Calendar1" runat="server" BackColor="#FFFFCC" BorderColor="#FFCC66"
BorderWidth="1px" DayNameFormat="Shortest" Font-Names="Verdana" Font-Size="8pt"
ForeColor="#663399" Height="200px" ShowGridLines="True" Width="220px" OnSelectionChanged="Calendar1_SelectionChanged" VisibleDate="2008-04-16">
<SelectedDayStyle BackColor="#CCCCFF" Font-Bold="True" />
<TodayDayStyle BackColor="#FFCC66" ForeColor="White" />
<SelectorStyle BackColor="#FFCC66" />
<OtherMonthDayStyle ForeColor="#CC9966" />
<NextPrevStyle Font-Size="9pt" ForeColor="#FFFFCC" />
<DayHeaderStyle BackColor="#FFCC66" Font-Bold="True" Height="1px" />
<TitleStyle BackColor="#990000" Font-Bold="True" Font-Size="9pt" ForeColor="#FFFFCC" />
</asp:Calendar>
</p>
And it the like is there, but still it does not do anything
Thanks

the url of your image is
http://www.tiyaneproperties.co.za/httpdocs/images/tiyane2.jpg[^]
It results in a 404. So the image is not there on your webserver. That is why it is not showing.
your page code is:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="index.aspx.cs" Inherits="httpdocs_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<br />
<br />
<asp:Image ID="Image1" runat="server" Height="184px" ImageUrl="~/httpdocs/images/tiyane2.jpg"
Width="520px" /><br />
<br />
<span style="font-size: 24pt; font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman';
mso-ansi-language: EN-GB; mso-fareast-language: EN-GB; mso-bidi-language: AR-SA">
<strong>
Under Construction</strong></span></div>
</form>
</body>
</html>
It does not say anything about your Calendar Control.
Have you published your latest codings on the webserver?

2 - a server control emits HTML based on code that runs on the server. Normal HTML controls are spit out verbatim. If you add any attributes to a server control that the server does not recognise, it passes them through verbatim to the client, no other code you enter on a server control makes it to the client, it just tells the framework what code to generate.
