Hi,
I have a datagrid populated from a dataset. On every row in the grid I have
a delete button. When the user presses on the delete button I remove the
row from the dataset and rebind the datagrid.
The problem is that after a couple of delete the index in the dataset does
not match the index in the grid and the wrong record i deleted from the
dataset. How can I solve this Problem? I am using the following procedure:

Hello
I have a problem deleting rows from a datagrid that is bound to a dataset. The datagrid updates and inserts just fin
so the binding to the dataset must be ok. However when I try to delete a row from the grid it sometimes works and sometime

any ideas what is going wrong

ArrayList. My situation is as follows:
I have two DataGrids on a modal form. The top grid populates an
ArrayList from a file, then the datagrid is bound to it, and it works

the same type as the first ArrayList. Both DataGrids are set to
Read-Only.
The user selects a row from the top DataGrid, then...

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

For most users, this new feature is actually very convenient. If you want to control the update process,...
