In my user contol I am creating a set of dropdownlists.
Each list is created based on input from the other lists.
The problem I am having is setting the selected index on
the lists.
If someone changes box1, I want to set the selected index in
box2 = 0. When I do this, I dont get an error, but when the
page loads, it still has the selected value and not 0.
It seems that it is getting the selected value from the viewstate

I'm using a viewstate key/value to store a serialized instance of a class.
If I redirect to another aspx page, the viewstate is lost. Is this the
intended behavior of the viewstate? Is there a work around? Cookies, I
suppose.
Thanks,
Craig Buchanan

viewstate?
When my control is created, it's ListItems are checked as needed, but on a
postback, they loose their Selected status.

Being a newbie regarding serialization and memorystreams, I was trying to
see if i could improve page performance (avoiding going to the db on a
postback) by saving my serialized business object in viewstate and getting
it back from the client on a postback. But the last line of the sample code
below throws a "Stream was not readable" error when i'm trying to get the
serialized object back out of the viewstate and memorystream.

Been a while since I've touched asp.net but one thing that always seems to
fustrate me is the loss of state on variable declarations. Is there anyway
(i.e. assigning an attribute etc) to instruct the server to remember a
variables state *without* having to go through the rigmarole of saving and
loading to and from the Session state manually or similar workaround for any
Types (including custom types) in exactly the same way web controls...

I have some potentially large objects I would like to store in the
viewstate of a user control. Large as in an entire email message. Is
ViewState not the sort of place to store such an object?
I think my question and concern depends on what asp.net does with the
view state when the page is written to the browser. Is the entire
viewstate contents written to the browser as a hidden field? Or are
the view state contents stored on the...

Hello,
I'm receiving The state information is invalid for this page and might be corrupted error message when running code below. This happens on second post back. Why is it happening?
My webpage contains 2 dropdowns controls and I save information entered by user in ViewState variable containing array
ArrayList MyCoordinates = (ArrayList) ViewState ;
if (MyCoordinates == null)
{
MyCoordinates = new ArrayList ();

Hi,
I need to get serialized string of Page ViewState in Constructor of my
custom web control.
I can not override SavePageStateToPersistenceMedium Method of page
object because I'm in different class. and Page.ViewState is not
serializable.
Is there any way to get serialized string of ViewState without
overriding SavePageStateToPersistenceMedium ?

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...

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