Seems like its not able to find the Checkboxes. Are you using TemplateField for the CheckBoxes? If yes, place a checkbox in the EditTemplate with respective names.

That mean your lblTotal or _ordersBLL.Total is null. Debug your code check which object returns null

It cannot be done using one control. However, it can be done using CSS and HTML. Probably this site will be useful. Check here

Yes. Response will not work for Update Panel.
You need to trigger that event as PostBackEvent.
Example.
<triggers>
<asp:postbacktrigger controlid="DownloadLinkButtonID" />
</triggers>

if My domain is "pmtt.net"
How send a mail use Gmail or Hotmail,
Or configure my own mail domain for send email?
Thanks.

You may use either web.config or asp.net configuration to specify the SMTP Server..
You need to remember that Hotmail and Gmail requires proper authentication so you need to provide an username and password as well.
Thereafter, you need to code the mail which you will be sending. Here is a small code snippet which does this:
SmtpClient smtpClient1 = new SmtpClient("ServerName", "smtpPort");
MailAddress fromEmailAddress = new MailAddress("fromEmailAddress");
MailAddress toEmailAddress = new MailAddress("toEmailAddress");
MailMessage msg = new MailMessage(fromEmailAddress, toEmailAddress);
msg.Subject = "Password sent";
smtpClient1.Send(msg);

Hi guys,
(sorry - lot of description about why I have an issue. My question is at the very bottom of this post...)
we have a scenario with several (more or less identical) Moss applications for different clients. Reports are the main part of it; these reports are identical as well for the clients but have to be deployed in each clients application. We display these reports using the Report viewer webpart that comes with the Reporting Services Add-on for Sharepoint.
I successfully set up kerberos auth and the RS integration. Using the ReportServer2006 (!) proxy I can programatically deploy the reports and manipulate their data sources. So far, so good.
Now there is one issue: I can deploy the reports _once_ - as soon as I try to deploy a second 'instance' of a report to a second application, the first entry in the 'Catalog' table of the ReportServer database gets deleted. So the last application gets stripped of its reports when the following application gets its reports deployed. This strange behavior does not affect the data sources; these can exist in several equally named copies in the table having different paths (URLs) for the different applications.
An obvious workaround: Rename the reports when deploying - e.g. 'Client1_ReportXY.rdl'. Works like a charm as expected.
But now we have n applications getting deployed via stsadm -o backup / restore from a template. Of course the Report Viewer webparts of the template don't know about the new names of the reports.
So I dug into the Sharepoint Object Model to try and update the reports' names in the Report Viewer webparts. I'm new in Sharepoint programming.
HERE IS MY ACTUAL PROBLEM: I can get hold of all the webparts on the page using SPLimitedWebPartManager - but the Report Viewer webpart doesn't show up in the SPLimitedWebPartCollection. Why is this? Is there any way to programmatically manipulate this webpart on an existing MOSS Page?
http://technet.microsoft.com/en-us/library/bb326422.aspx[^] points out that the Report Viewer webpart is a 'Custom Web Part'. Is this the cause - can't I access custom webparts via the object model?
Thanks for reading, any suggestions welcome. Actually I'm thinking of switching back to RS native mode - there have been lots of problems with the MOSS integration. And overall MOSS itself gave me more of a hard time than it actually helped
