Hi all,
I'm getting a bug with the datagrid object.
I've created one from scratch, bound it to a dataview with 2 int32
columns and formatted the output as currency.
I've found that when you use the F2 key to enter edit mode and then
hit TAB or ESCAPE without actually editing the value, dotnet crashes
with a null reference error.

I need some help programmatically causing a row in a DataGrid to "flush"
its contents to its bound data (in Visual Studio 6 using Windows Forms
with C#).
My issue is I want to send an update to a database from a menu command
while the user is editing a DataGrid. This is unusual in regard to
examples and normal practice in that the cell of the DataGrid still has
the focus. In all examples I can find, the user normally presses a
button on...

Hi All
I got a datagrid and a ComboBox on a form. I populate the combobox with
years for all the data avaiable. When the user chooses a year the datagrid
is populated with the specific years information.
Problem... when the users scrolls the datagrid with the mouse wheel it work
for 2 wheel clicks and then for some reason the focus jumps to the combobox
and the year is then changes there for causing the data to change and errors...

Hi,
I need a big help to resolve this problem.
I need to put a usercontrol in a datagrid: this control check if the code
inserted is present in a archive and if not return a error message.
(In the example I have changed this check with a easy "if string is empty" )
Everything would be easy if the datagrid had a predictable behaviour.
I explain my problem.

Hi,
This is a very common issue. I have a read only Windows Application
datagrid, on which i want to prevent the tabbing between the columns and
rows.
What needs to happen is this:
When i hit tab and land on the grid, I have to scroll through the rows using
the up/dwon keys .
When I hit tab when I'm on the grid, i need to set the focus onto the next

The LostFocus event of datagrids is fired when the focus is added to a
cell. How do you go about detecting it when the control as a whole has
lost focus to another control?
Slightly confused by 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

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,...
