I am trying to detect what asp.net button was clicked duing the
page_load event. I have two asp.net buttons on my page.
What is the easiest way to detect this? 8 2662
Is there some overarching reason that you picked the Page_Load event? How
about using an Event Handler?

There is no easy way.
If they are link buttons, you can look at Request.Form["_eventtarg et"];
if they are buttons, if the id of the button is in request.form, then that's
the button that was clicked..

I appreciate (sorry ) that I'm not answering your question, but normal
process would be to handle that in the buttons click events. You may be
heading the wrong way if your trying to work around that.
What are you trying to achieve?
I've come across situations where I've cheated on this one also. Typically
it's performance related (not a mindless micro-optimisation either)...
But I agree that it should be called into question and thoroughly examined
:)

Yes, of course I would usually handle this in the normal event handler.
But for my case I want to do something like this in my page_load
if(page.ispostb ack)
{
if (button1 was clicked)
{
//do something
}
else
{
//do some normal postack type stuff
}
}
You can also always render a hidden field in your page and set that
value = to a unique button string identifier in the onlick javascript
for the two buttons. Then on page load you could just check that
hidden field value. Make sure you either declare that hidden field in
the web page or add it in the Init() method, though, otherwise it won't
participant in the load post data phase.
ASP.NET is kindof retarded about this. You would think they would
expose an easy way to let us get this kindof information in the page
load.

C#
if(null != Request.Form["buttonName "])
{
// buttonName was clicked
}

If Not Request.Form("b uttonName") Is Nothing Then
' buttonName was clicked
End If

I have quite a few pages that have multiple command buttons on them - for

what gets displayed in the page depends on which command button was clicked

I have Form1.aspx. Form1 uses client side javascript to launch Form2.aspx
when a button is clicked:

The first time the Form1 button is clicked the Form2 Page_Load (server side)
is fired.
I close Form2 returning to Form1. Click the button again. This time when

Hello,
In my form I have a button, and the button_Click function
(which gets called when the button is clicked). However
the functionality that I have in the button_Click
function, needs to be in the Page_Load, since I need to
change a value based on the button click to render the
page. So my question is, can I access the button object
(the sender of the event) in the Page_Load. So that in
the Page_Load I can have the following...

I have a problem with the order of events fired by ASP.NET. I found many

Here is what I want to do:
I have a Button, which starts a new search session. When this session is

When a Button is clicked in a Web Form in an ASPX page, the Form will
post back to itself. Under such circumstances (i.e. when a Button is
clicked), will the Page_Load sub execute first & then will the Click
event function of the Button execute or will the Click event function
of the Button execute first & then will the Page_Load sub execute?
Thanks,

I need to understand why if I add a control and use AddHandler to connect its
click event, it will work in Page_Load, but not in a Button_Click.
The idea is that the user types some data, presses the button, gets a list
of results (each with a LinkButton) and can then press one of the link
buttons to get further information. The newly added link buttons appear, but
the click event added with AddHandler does not fire.
