Hello All,
I am having a problem with events and the addition of
controls on a page I am developing. First let me tell you
what I have tried and then maybe someone can see something
I missed.
First I tried adding the controls and the event handlers
for my control in the Initialize Components method of my
page in the hopes that it would fire the event before the

All,
I have a CONTROL that contains 1 control (Control ONE), the 1 control that
it can contain 1 or 2 control (Control A and B).
Control A, raises and event and Control ONE receives this event and this
causes control B to be created, when this is done the VIEWSTATE is lost for
CONTROL B.
In the EVENT that causes CONTROL B to be created I have to set

Hi,
We are developing an asp.net application, and we dynamically created certain literal controls to represent some read-only text for certain editable controls. However, recently we found an issue which is related to the repeater. In the code shown below, if I call Repeater1.Controls.Count in the OnInit (the code fragment was highlighted in yellow) , the viewstate for the repeater will be lost during the postback. You can re-produce this...

I created a custom DataGridColumn based on Marcie Robillard's MSDN
Article:
Creating Custom Columns for the ASP.NET Datagrid
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspp/html/creatingcustomcolumns.asp
The problem I am having is that the data in the custom datagridcolumn
is not saved to viewstate and after postback, the column does not
contain data.

I have a very simple custom control that derives from WebControls.Panel and
implements INamingContainer.
It appear that controls created as children of my custom control are having
ViewState problems. For example, suppose I create a ListBox control as a
child of my custom control, attach a SelectedIndexChanged event handler to
it, and bind its data in the Page_Load event handler only if the current
request is not a post back. I load the...

I am building a custom composite control consisting of two drop downs,
with parent/child dependancy.
The child dropdownlist is updated through client callback when the
parent index changes.
An 'All' list item is added to the child dropdown during the
CreateControlHeirarchy(bool useDataSource) method.
Somewhere between the CreateControlHeirarchy method executing and the

I have an app that was originally 1.1, now migrated to 2.0 and have run into
some sporadic viewstate errors...usually saying the viewstate is invalid,

I have a CompositeControl with two types of properties:
1.) Mapped Properties that map directly to a child control's properties
(ex.: this.TextboxText = m_txt.Text). These properties are handled by their
underlying classes (such as the TextBox control), and are not persisted by me.
2.) Unique Properties that don't map directly and are persisted in ViewState
(ex.: this.LabelPosition, which specifies where on the form the label should

v1.1 and v2.0
We have a problem with viewstate not being stored.
What's happening is that we create controls in CreateChildControls and add them to a container on the page (whether it be a panel or
a table etc). We only set the data values for the controls if not page.ispostback. But, if either of the textboxes change,
the page posts back and the changed event fires twice.

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:

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

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
