I am a beginner ASP.NET C# developer and have a question about a concept. When I declare a function, I have something generic like:
public void sample_function(object sender, EventArgs e)
{
//function code
}
What I want to know is what does the "object sender and EventArgs e" stand for? How can I use these?
protected void ok_Click(object sender, EventArgs e)

View 2 RepliesProtected Sub FormView1_ItemCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewCommandEventArgs) Handles FormView1.ItemCreated
Causes Unable to cast object of type 'System.EventArgs' to type 'System.Web.UI.WebControls.FormViewCommandEventArgs'.
The program (asp.net/vb) works fine with FormView1_ItemCommand and FormView1_ItemInserted events but strangely objects to FormView1_ItemCreated. Is it only a VC# event?
I have Sub that requires EventArgs as below.
Sub Testing(ByVal sender As Object, ByVal e As EventArgs)
If I want to call the Sub from PageLoad event, I wrote like this Testing(nothing,nothing)
Then, in the Sub, I would like to check If Argment is Nothing or not
Dim testID As String
If (CType(sender, LinkButton).CommandArgument) = Nothing
testID=Request.QuerySting("myID")
ELSE
testID=(CType(sender, LinkButton).CommandArgument).ToString
End If
I get Null error at if statement (If (CType(sender, LinkButton).CommandArgument) = Nothing)
This may be a basic question. I know __doPostback() function accepts 2 arguments, eventtarget and eventargs. eventtarget is used to identify the control that causes postback. Then what is the use of eventargs in doPostback function?? I saw the _doPostback function always set the __EVENTARGUMENT hidden field to nothing for any postbacks caused thro controls with even autopostback to true or a control like linkButton.
View 2 Replies what I can replace the bold line with to get it working with EventArgs e? I copied this code from a button function with CommandEventArgs e.

I have two buttons in a list view that adjust the position of that item, basically, moves it up or moves it down. Both buttons have the CommandName="Select" so I need to know if their ID is somewhere in the EventArgs so I can tell if the Up or the Down button was pressed.This is my temporary sol'n, maybe it'll give you a better idea of what I mean to do.int s;
public void iBtnUp_Click( object sender, EventArgs e )
{
s = 1;

I have a server side control RaiseCallbackEvent implemented. I want to intercept raisecallbackevent after it finished executing RaiseCallbackEvent method in the serverside and want to execute other code in the .aspx template.
1) Is there any pagelife cycle event that fires after RaiseCallbackEvent?
2) Is there any way to fire jquery function after RaiseCallbackEvent from client side?
Argh.. I've run into thei before,but can't remember how I solved it.I have a gridview with a button in a template field.I've added an event to the button,but am getting the dreaded 'RowIndex' is not a member of 'System.EventArgs' error.
I'm trying to grab the value of a label in the gridview for the row that is selected when the button is clicked.Should I be using something other than e.RowIndex?

View 2 RepliesI am new to mobile development. However, I am familiar with ASP.NET and VS. I have the following requirement:
An email is sent to approvee a PO to an email address, say xyz@abc.com. The email has a YES/NO button. The person receiving the email selects one of them. Based on the selection, an XML needs to be generated that is sent back.
Where do I start to learn this?
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 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 1 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;
