Here is an odd issue. I am trying to shed some light on why this is causing
a problem.
I have an ArrayList. I am binding it to a ListBox control with has its Sort
property set to True. If the ArrayList only has one element in it everything
works ok. But as soon as I have more than one element, I get the following
exception when the control loads up: "Cannot modify the Items collection
when the DataSource property is set.".

It is best to copy/paste into notepad to get the spacing correct.
I have a dataset that contains 3 tables. Two of the tables contain
data and the third links them together. The dataset has a constraint
setup as well.
The first listbox and the first and last name text box are bound to

Hi
I have a question about whether Data Binding can facilitate the process of saving data in a web application
I learned that you can data bind information from a number of different data sources to controls such as TextBox, ListBox, etc. I am clear on the concept of data flowing from data sources into web forms controls
What I am not clear about is how to make the data flow the other way. When I am ready to save the changes or add a...

child table contains an ID field (which is configured as autonumber in the
datatable), the ID of the parent, plus some addition fields.
I'm able to get the datagrid to be properly populate with only the child
records relating to the specified parent by setting the
..DefaultView.RowFilter property.
Currently, to properly add a new child record, I need to manually...

I'm trying to fill a listBox control with string members from an array
of objects. I think using data binding is supposed to be the easiest
way to do this. I've never used data binding before and am having
trouble getting it to do anything. The relevant code is below, followed
by a better explanation of what I'm trying to do.
// pseudocode start
public delegate string StepMethod();

Hi,
I have an ASP.NET page with a ListBox that is data bound to a table
with a single field (it holds a list of valid IDs). The page also has
a textBox into which you can add new valid IDs, one per line (this is
in order to make the process of adding new IDs easy, since it's only
done at time of configuration).
I have no problem with retrieving the contents of the textBox,
splitting it into a string array, validating the individual...

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,...
