I am trying to use a DataGridView to display one column of textboxes with a
single value from a query and then next to it have a combobox that displays
results from another query. What happens is the second query just returns 1
value to each combobox. So, in other words, for each textbox, the next
result of the second query puts 1 value in the corresponding combobox.
Here is my code... What the heck am I doing wrong????

I have a datagridview with some columns.
One of them has been declared as a DatagridviewComboboxColumn
The datasource of this column is a table of an Access Database. There is
13000 lines in this table, but only 3 fields.
In runtime, when I click on this column, the combobox is very long to open,
and each time I click on the combo box on another row, I must wait for a too
long time to see list..

I am programmatically building and populating a table and then making it the
data source for a dataGridView. I want to add a column to the dataGridView
which will be a DataGridViewComboBoxColumn. I wish to populate, by default,
all of the ComboBoxes with the same list of three choices.
How do I add the DataGridViewComboBoxColumn, and do I first populate one as
a template for the others?
I will appreciate any help.

How do other people get around having to define the ValueMember in a
DataGridViewComboBoxColumn when binding to a list of business objects?
I'm currently doing the following, and it feels wrong and woefully
misguided.

private string name;

Hi
I have a little application that does datavalidation.
It supports dynamically loaded plugins (you drop a dll with a class
implementing IValidator<Tin the same dir as the main application).
All classes that implement this interface are shown in a drop down in
a DataGridViewComboBoxColumn named Validator.
By choosing the class to validate this specific data in the drop
downbox IValidator<T>.Validate is called and returns true/false....

I have a DataGridView bound to a custom business object. The business

I have tried to use the DataGridComboBoxColumn object with limited success.
What I want to do is to create one new unbound column to be a combo box (so
far, this has worked), populate it with items from the database (this also
has worked). But, now I want to be able to have the user select one of the
items in that combo box and fire off an event to select more data from the
database based on what the user selected in the combo box.

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
