Hi all,
I was wondering if anyone can help me with a really annoying problem I have
been having. I made a derived datagrid class that will select the row when
a user clicks anywhere on a cell (multi-select without modifier keys). I
got that working fine, but I also wanted to keep rows selected after a sort,
which I do by storing the row's id in an arraylist. The idea was to do the
sort and then go back and re-select the rows with that...

hey guys...
I'm trying to make my DataGrid have selection behavior similar to
WindowsExplorer, where I can hold CTRL to add rows to a multi-row selection.
Thanks to someone else on this newsgroup, I found out how to detect if CTRL
is pressed while in my MouseUp event, which is when it's supposed add that
row to the selection. (Otherwise, if the CTRL key is not pressed I clear any
current selection to start over- just like Explorer)

Hi,
I'm using a ComboBox, some Textboxes, and a DataGrid to represent a
many-to-many relationship between Person and Course. Each time that I change
the value in the ComboBox (which for now is the OID of Person), the
information of the person matching the selected OID is shown in the Textboxes
(Name, Address, id, etc) and the courses this person is taken are shown in a
DataGrid (course name, price, etc.). This is working well so far, I...

Hi,
I have a datagrid with dropdown list and Remove hyperlink in it as
columns.
When I remove a row from the datagrid, Dropdown list selection is
retaining its previous value. i.e, removed Dropdown item selection is
applied to the next dropdown list.
Is there any way to fix this problem?

The Source Fields are "Name", "Value", "Locked"

All,
I have a datagrid that I use in a ASP.net web page that loads customer data
based on the selected customer ID
Some Customers will have no data in the database (which is oracle 9.2) . So
I check the .HasRows property first then if it is false I skip the data bind
like so
If OraReader.HasRows Then
grdCustomerDetails.AutoGenerateColumns = False
grdCustomerDetails.DataSource = OraReader

Hello, and thank you in advance for any help you can provide.
Each line in our datagrid control contains a product number,
description, and a textbox for the user to enter a quantity-to-order.
Users enter quantities (not necessarily on every line), click the Next
button, and continue. Sometimes users return to a previous page, by
clicking the Previous button, and see quantities that they did not
enter. More often, users return to a...

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...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
