hi,
had a question on preloading a dropdown. we have a textbox and
dropdown on the page, user is suppose to enter in a zip into textbox,
then the dropdown should load the state based on the zip. we can pull
the state from the database on a zip match table, but how do we preload
the dropdown, is there a way without posting back?

I have a page that works fine. I am trying to optimize the page by
overriding some of the Information that is being saved in the hidden
VIEWSTATE.
If I make the properties of the dropdown False for ViewState and True for
AutoPostBack, it does reload the page but does not call the
SelectedIndexChanged event. If I put the ViewState to True then it is
called.
Does this mean that I cannot get that event and deal with it in better code

I don't know how this is happening, but a dropdown control I have is
resetting to the 2nd value on the list anytime a postback occurs.
I have no initiation code outside of
If Not (IsPostBack)
I have EnableViewState set to true for the control - the control stays
populated, it just is losing its selected value.
The control is not contained in any panels or anything, just a Web

I have two dropdown lists. Both have autopostback set to true. In both
dropdowns, when you select an item from the list, it redirects to the Value
property of the dropdown. Nothing fancy.
Let's say you select 1 of the items, and are properly redirected. You press
the back button. I have three servers providing two different
functionalities:
1. After pressing the back button, the item you selected in the dropdown is
still selected.

Hi,
I have 2 dropdown lists on an ASP.Net page, the first is a list of states of
US, the second is City list. When user selects a state, the web page does a
postback, create a DB connection and bind a dataset to city dropdown list.
This is working for me.
But I would like to do this on the client side for the following reasons:
(1) Doing this on server side takes time, the postback and connecting to DB
costs too much.

During a postback event, I am having trouble retrieving the state of a
CheckBox Control that I am dynamically adding to a DataGrid Control using
ASP.NET 1.1.
I have no trouble adding the TemplateColumn dynamically. I persist a DataSet
in my Session object and I bind the CheckBox to the DataSet. So far so good.
The CheckBoxes show up and the user interacts with them (checks a few,
unchecks a few).
The problem is that during a postback...

Hi,
Currently iam facing a strange problem.. One dropdown in my page is
keeping itz state after postback. Whichever the item i selected is not the
selected item after postback. it goes back to the first item again. This
happens even if i submitted the page by making the AutoPostback of the
dropdown true or by clicking on the submit button. Even itz not going to the
DropDownList1_SelectedIndexChanged method.

Hi
I'm having a problem in adding controls to a page programmatically in
response to a button click.
Composite user controls added programmatically in the
CreateChildControls() method work fine; they maintain their state as
expected. Cool and groovy. However, since CreateChildControls() is
called before the method that responds to the button click, say
AddControl_Click(), for some reason, this control does not maintain its

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:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
