Hi.
I have a button called btnSelect on a web form. There is a handler for it.
However, the Page_Load() gets called before the handler gets called.
I want to do the following. In the Page_Load(), I want to check if the
btnSelect caused the event. How can I do this?
Please help.

Take a look at the values available int Request object; you should be able
to find the information you need because all the information send by the
POST submission of the form is there.
However, I'm not sure is this is the right thing to do. Instead, you should
isolate the relevant code in a subroutine and call it from the btnSelect
event.

Yes. You are right about the form submission with the post. I can get the
information. However, this is a little different story.
This has more to do with postback and capturing events.
The question is, "How do I check what object caused this event for it to
come to Page_Load()?".
Please help.

I'm sorry, but I don't know the answer to your question.
Maybe the following article will give you a starting point for your
research: http://msdn.microsoft.com/library/de...bjectmodel.asp

Hi
The loadevent is called everytime a page is loaded or/and is postedback
There is no need to check in that page the handling of the button event,
that you can do in the button click event it self (when you do not know
that, than message back)
For to prevent that unwanted actions are taken on postback is the IsPostback
property, very easy to use and well desctripted on this page. http://msdn.microsoft.com/library/de...tbacktopic.asp
I hope this helps?
Merry Christmas
Cor
Cor,
Here is my problem. I have a datagrid with sort columns. One of those
columns is a checkbox column. And, I have a button regular button with
postback.
My page_load() looks something like this:
void page_load(..)
{
If (!IsPostBack)
{
Session["SortColumn"] = "AgentID";
Session["SortOrder"] = "Asc";
}
BindData();
}
When I click on a column header, it sorts by the sort order. So, I need to
call BindData(). When I click on a button called "Select", I don't need to
call BindData() and display the checkboxes that are checked prior to pressing
the button. I do have the button handler, but the Page_Load is called before
the handler gets called.
I need to determine if the original event is caused by the button or
something else in order to prevent the datagrid binding data every time.
Your input is appreciated.

J,
Probably when you see this than you think something as Ohhhh me My page_load() looks something like this:
void page_load(..) { If (!IsPostBack) { Session["SortColumn"] = "AgentID"; Session["SortOrder"] = "Asc";
BindData();
}
}
And you do the BindData() as normal in your clickevent at the time when it
should be done.
I hope this helps?
Cor
Cor is right. Move BindData into your if statement and then call it as
needed in the click event for the column sort.
Then, when the user clicks select, you won't run into a BindData call along
the way.

Aha! It's a good try, but here is something to consider. If I move the
BindData() to the !IsPostBack section, and then, I press a column header, it
won't show any data because BindData() isn't being called. SOmehow, I need
to prevent BindData() only when it is caused by the "select" button.

Thanks for the suggestion. I did stick the BindData() in the !isPostBack
block. In the process, I learned that my columns were sorting only because
BindData() was called everytime. Since I moved BindData() into the
!IsPostBack block, my columns don't sort when I click on a column header. I
learned that TemplateColumn does not generate the sort event.
I need to be able to sort using the TemplateColumn. Please help.

Jack,
On what other places did you do the databind, because you have probably to
do the databind in most of your events.
From your post I am still not sure you do that?
Show us some more code, especially from an event where you do some actions
with your sortcode session.
Cor
both Cor and I asked you to move the BindData into the PostBack and then
ALSO call BindData in each of the events where you want the sort to occur.
I'm not sure that you understood that.

Thanks for the suggestion. I did stick the BindData() in the !isPostBack block. In the process, I learned that my columns were sorting only because BindData() was called everytime. Since I moved BindData() into the !IsPostBack block, my columns don't sort when I click on a column header. I learned that TemplateColumn does not generate the sort event.
Does anyone have any helpful information to sort when using TemplateColumn? I need to be able to sort using the TemplateColumn. Please help.
Thanks TheJackOfAll

I'm a little rusty having not touched .NET for 6 months and
I can't remember why Page_Load is happening twice in this code:
private void Page_Load(object sender, System.EventArgs e)
{
//existing session?
if (Session == null)
{
//save local empty order object
this._newOrder = Orders.Initialize();

Hi all,
I have a site with the following architecture:

I am using ASP.NET 2005 and I have a simple form. Page_Load calls a

On every single ASPX page in my site, Page_Load gets called twice. Why
is that and how can I fix this problem ?
Thank you very much.
