View 9 Replies I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button
Data Data Button
Data Data Data Button
Data Data Button
Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
sender.CommandArgument
for example returns and empty string.
i have explicitly added __doPostBack() on Button onclientClick event .

When I am clicking the button the Page_Load is calling twice.
But if I am adding below code inside page load ,page load is calling only once on button click.

and return true is giving me again twice page load ,but adding return true or false in attribute.add code is giving the same result ,only one page load call.

I am not able to understand what is going on exactly I try to add __doPostBack in different way.
This should be an easy solution but I get stuck with it and hope I can get some advice/guidance from you:I have a simple aspx page with a Paypal button in it. The code shows in .aspx page:

I am designing a page wherein I want to display just parts of a page on page_load (i.e. menu bar). Then a few seconds later, I would like to display the rest of the controls (i.e. charts). Is this possible? What I currently have is a page that displays the page skeleton and then on button_click(), the rest of the page is rendered. I want to fire a button_click() event on code-behind without actually requiring the user to click on the button but can't seem to find good tutorials/articles regarding this approach.
View 5 RepliesI have explicitly added __doPostBack() on Button onclientClick event.
<asp:Button ID="Button1" runat="server" Text="Button"
OnClientClick="__doPostBack('Button1','')"/>
When I am clicking the button the Page_Load is calling twice. But if I am adding below code inside page load ,page load is calling only once on button click.
Button1.Attributes.Add("onClientClick", "__doPostBack('Button1','')");
Again if i add with return false it is giving me it calling only once page load on click
<asp:Button ID="Button1" runat="server" Text="Button"
OnClientClick="__doPostBack('Button1','');return false;"/>
and return true is giving me again twice page load ,but adding return true or false in attribute.add code is giving the same result ,only one page load call.
Button1.Attributes.Add("onClientClick", "__doPostBack('Button1','');return true;");

Every time we click on a button. the Page_Load will fire first.
For my case, I have some controls added programmatically to the GridView, when the button click, the Page_Load event fire, my controls just go away.
I have a very common problem with asp.net . I have designed a webpage that performs some action on its load event but whenever a user clicks on back button those actions are not performed as Page_Load event is not called.I have searched a lot of forums but wasn't able to get a exact answer. All I was able to know that it was happening due to cache memory maintained by browsers. I don't want to delete that cache. I want browser to work in normal way.
View 3 RepliesI have a set of 4 buttons which part of a gridview template and I load the gridview on page_load. The datasource for the gridview comes via my controller as I am using Microsoft's Model View Controller design pattern. I set 4 public properties for each of the 4 buttons, which I can access in my controller class/method. However, when I call the method for the gridview, which sets the datasource for it on page_load, I get an error message when I try to set the enable to false. It says "Object not set to instance of object". The objective I am trying to do here is a check on a returned value, which I can achieve, and based on the return of the value that is returned, to either set the button enable to true or to false.
Unfortunately, I am getting this Object not set to instance of object error message, and I do not know how to resolve it.

I am not sure exactly what javascript calls it, but in vb and c# it would be called "sender". I want to use one function with some slight changes in it that depend on the sender.

I have a list of ajax actionlinks that are supposed to call a javascript function on success. The function is supposed to change the css class of the parent div. I tried it two ways, both have a weird problem with them. This is the function they are calling:

This is the list of actionlinks:

When I run this code, the OnSuccess function gets called right away, before the ajax call has returned. That's no good. If I change it to OnSuccess="SetSelected" it waits for the ajax call to return, but the javascript funtion fails because I'm not passing any values to it. How am I supposed to do this, and get none of the unwanted behavior?
I'm accessing all my mails in Exchange Server programmatically. first I load them: item.Load(); then I have to know the sender. But I can't see a property that allows me know it.
View 1 RepliesI have a couple of web applications which all utilize sending emails whether it be by contact form, or some kind of notification updates etc. The problem I have found is that there isn't really any way to track the emails which are being sent from the web applications, so I've come up with a possible solution: It's pretty straight forward really - instead of having each web application sending the emails themselves I would like to unify the process by creating a central Email Sender Service.
In basic terms, each application would just create a row in a 'Outbound Emails' table on the database with To,From,Subject,Content data. The Email Sender Service (Win Service) would then pick the emails from the outbox, send them and then mark as sent.
Even though I would store 'basic email' information (to,from,subject,content) in the database, what I would really like to do is also store the 'MailMessage' object itself so that the Email Sender Service could then de-serialize the original MailMessage as this would allow any application to fully customize the email. Are there any problems with using the MailMessage object in this way? Update: Another objective, is to store a log of emails that have been sent - hence the reason for using a database.
I have a master page with a button that triggers a callback event. It works fine however, the content page's page_load event is raised when the button is clicked. The logic within the content page's page_load event is specific to the page and not to anything on the master page. How do I determine the sender of the callback event so that I can skip any logic to be performed in the content page's page_load event?
View 4 RepliesI am working on a application which will accept the data in the post request.I will surely implement the data encryption to make sure that communication is secured. But my concern is, any body who knows the URL will be able to send the POST data request to my application, can I restrict the request from once specific IP address/URL.From a Request object can I find out which application/HOSTname/URL has sent this request. I looked at RefererURL but it can be populated and cannot be used. Is there any other field/properly which will tell me about the party who has sent this request.I want to make sure that I process request received from one specific URL/IP and want to ignore all others.

View 2 RepliesHow can I send a email message to just once person? When I use the following, I have to put in a valid sender address as well as the recipient address in order for my message to be sent. This will send two messages: One to the sender, and one to the recipient. How can I just have my application just send to the recipient only using the Smtp Client Class?
MailAddress fromAddress = new MailAddress(sender);
MailAddress toAddress = new MailAddress(recipient);
MailMessage message = new MailMessage(fromAddress, toAddress);
SmtpClient mailSender;
mailSender = new SmtpClient("Smtp.test.com", 25);
message.Bcc.Add(fromAddress);
message.Subject = subject;
message.IsBodyHtml = false;
message.Body = body;
