Hi,
Am I trying to hold the data of a DataGrid in a label so that when the form
is reposted the DataGrid can be repopulated. The problem I am having is that
I don't understand how to get the text into a stream in order to be able to
use DataSetOutcomes1.ReadXML(MyStream).
Thanks in advance,
James

Is there any way to delete the value of a html hidden input field from code-behind? I use an html hidden input to store an array of data. I collect this data using Request.Form or Request.Params. After I use it, I want to force the deletion of it, so a user cannot hit their refresh button on their browser and trigger the same events that just occurred.
I have tried using Request.Params.Remove("HiddenField"),...

Hi. I have a gridview control on a web form (asp.net 2.0) that's bound to a
objectDataSource. The objectdatasource which is bound to a class I've
written in the DAL to read and update the database. The grid contains three
columns - an ID (GUID), a name (string) and a rowversion (timestamp), and
the data is passed to/from the page in an instance of a data entity object.
When I open the page the grid loads properly, but if I attempt to edit...

I have a form that is built pretty much entirely at run time.
I load a collection of Categories which have multiple Plans.
Each Plan has a RadioButton.
Each Category has a single PriceTag TextBox that is populated with a
Price when a RadioButton is selected. This is done through a
Javascript method.

On a tab I have one DropDownList which requires a postback and two
ListBoxes which do not require any postback because I just have some
javascript, defined in the aspx file, to copy items from one listbox
to the other. All 3 of these controls exist in a table which is
inside an UpdatePanel. When the drop down list value changes and the
postback occurs the data that I had in my listbox control disappears.
How do I fix this?

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

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...
