I have been developing with C# User Controls and occasionally have a problem
where I "lose" a control from the design surface of the User Control. The
controls that I am using to build my User Controls are themselves custom
controls.
Occasionally, when I change something in either the User Control and/or one
of the custom controls that are on it and recompile, when I go to the
"Visual" design surface of the User Control, the...

I've noticed that none of the child controls events are firing for the first time from the dynamic user control. Here is the event cycle.
1) MainPage_load
2) User control1_Load
user clicks a dropdown in UC1

1) MainPage_Load
2) User Control_1 Load

Perhaps I'm just too new at this to pull it off, or perhaps it's just bad
architecture. I'd appreciate some feedback on the the wisdom (or lack
thereof) in attempting the following:
I'm not new to programming, but I am new to ASP.NET and Web application
design in general... loved the concept of user controls and dynamically

dynamically loads two user controls directly...

I have a web form with a button and a placeholder, the button adds a user
control to the placeholder (and removes any existing controls). The user
control contains a single button. I have done all the usual stuff of
recreating the usercontrol in the Page Init event.
The 'failure' sequence is as follows:
- select web form button to display the user control
- select user control button, event fires
- select web form button to display...

Hi All, I got a real doozy here. I have read hundreds upon hundreds of forum posts and found numerous others who have replicated this problem, but have yet to find a solution. Through testing I have been able to find the cause of the problem, and will describe it here first textually and then through a code example.

Here is the page architecture:
Page loads multiple user controls (including nested user controls)
dynamically based on parameters provided into place holders. Note: The
page only has the logic to load the user controls and subscribe to
custom event exposed in the user controls.
Scenario:
User comes to this page fills the fields generated by multiple user
controls and then hits "Save" button in one of the forms.

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:

Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
