I have a control called UniqueTextBox, that implements the
IPostBackDataHandler.
I have trying to use the control in a composite control called
UniqueTextBoxEx.
The LoadPostData method of the UniqueTextBox is never getting called.
What do I have to do to have child controls process their own postdata?

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).

I am getting a curious problem where LoadPostData is not being called after
registering the control using RegisterRequiresPostback. Other controls not
requiring postback registration are having LoadPostData called. Each
control calling RegisterRequiresPostback does have a uniqueid and exists for
the lifetime of the page, so it's not a mis-referencing problem.
It's worth noting that this was working fine until I killed the Viewstate
and...

I have a custom control (MyTextBox - taken from Microsoft website)
that implements the IPostBackDataHandler interface. It is added to
the controls collection of a placeholder control during the Page Load
of a main ASPX page. Now if we debug the MyTextBox, we find the order
of events like so (during a Posback, of course): OnInit -> OnLoad ->
LoadPostData.
My question is why does the LoadPostData occur *after* the OnLoad
instead of...

In my page load, I have the following
DropDownList.Attributes.Add ("onblur", Page.GetPostBackEventReference(this, "Update"))
The page itself implements IPostBackEventHandler (I don't want a custom control) as
#region IPostBackEventHandler Member
public void RaisePostBackEvent(string eventArgument
if (eventArgument == "Update"

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

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...

Hello there. My question is related to full custom server controls.
1) The 'input' element that caused the postback already has 'Me.UniqueID' in its name field. I assumed, the value of postDataKey is this UniqueID is that right?
2) How do you set (and retain) the values of the different properties across postback. For example i have some String properties (eg. SelectedItemNo, ImageUrl...), integers that i want to save according to which...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
