how come RaisePostBackEv ent doesn't work correctly if the
IPostBackDataHa ndler isnt implemented. It seems that I must at least have:
public bool LoadPostData(St ring postDataKey, NameValueCollec tion values) {
return false;
}
public void RaisePostDataCh angedEvent() {
}
In order for the eventArgument string to come through properly in:
public void RaisePostBackEv ent(String eventArgument) {
Anyone know why?
TIA

If you have IPostBackDataHa ndler implemented and you wish
IPostBackEventH andler.RaisePos tBackEvent called (means you have implemented
both interfaces), you'd need to use Page.RegisterRe quiresRaiseEven t to get
RaisePostBackEv ent called . Otherwise it is not called at postback
processing stage.
If this doesn't help, what kind of control it is in question? If it is a
composite one, you'd need to implement INamingContaine r interface for
postback data to be routed correctly. Post some more code.

Im asking why it doesnt work if you *dont* implement IPostBackDataHa ndler. I
dont need to do anything with either method of that interface.
If I do not implement that interface, my RaisePostBackEv ent is called but
the eventArgument is empty. If I do implement it, just in a barebones way,
as described below, eventArgument behaves correctly.

Hi all,
I've been struggling for the past few days to get a custom control to
pass events to RaisePostBackEvent.
My page successfully fires the RaisePostBackEvent, however, the
EventArugment is always nothing. I do not understand why the event
argument is not being passed (the doPostBack javascript seems to have
both parameters filled out).

hi,
I'm making a custom control that is rendered implementing the
IPostBackEventHandler interface, and have got it working fine for a single
submit button, but how do i pass arguments from the HTML page back to the
server, e.g. identify which button has been pressed.
At the moment i can only cause a postback by using a submit button, are
there any other ways? - i.e. can a do a manual javascript,
document.forms.submit() ?

1) Start a new web application in Visual Studio
2) Drop a CheckBox onto the form and set its AutoPostBack to TRUE
3) In the codebehind, override the RaisePostBackEvent event with:
protected override void RaisePostBackEvent(
IPostBackEventHandler sourceControl, string eventArgument) {
base.RaisePostBackEvent(sourceControl, eventArgument);
}
4) Set a breakpoint in the event handler

I've created a control within a Web Control library, using ASP.NET 1.1 (VB.NET). The control has a value property and a ValueChanged event.
I have implemented the IPostBackEventHandler interface and have ensured that my control renders using the UniqueID. I have not added any code associated with an AutoPostBack, because it did not seem necessary for the application.
My control works great when I drop a single instance onto the web form....

ASP.NET RaisePostbackEvent Issues
I ran into some problems on a particular page in an application. Only on that page, for the same control that worked in other pages, the RaisePostbackEvent was not being called, even if the “__EVENTTARGET” value from the post collection was the same as the UniqueID of my control.
After a while i discovered that the event was raised but for another control in the page.
I read the msdn documentation on the...

Hi!
I'm building an ASP.NET application using master pages, but there is a
problem that I can't solve.
In a master page there are some controls and some controlplaceholders,
that I fill programmatically in some "slave" pages. In normal
development, without Master Pages, I managed particular cases
overriding RaisePostBackEvent function, provided from the page. This
procedure works fine, in old applications.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
