I created a collection which is derived from ArrayList and implements
IBindingList and ITypedList.
Then I bound the DataSource of a data grid into the collection. It could
show up the data but the column heading is not in the right order, for eg. I
want "ID" column to be the first column but it showed as the second column.
Another problem is that anyway i can leave a blank row in the grid to add a
new row automatically if the user...

Dear NG,
After being away from C# programming for a spell, I am trying my hand at
what should be a simple task. I have been hitting my head against the wall
this morning. I have a simple order entry application. The code below gets
line items from a SQL Server database and returns them to a datagrid by way
of a DataTable called lineTable. As long as I am just displaying columns in
the SQL database everything works well. I now want...

I have a simple datagrid on a webform. (I'm using VB.NET.)
In the page load I get some data, set the .DataSource property of the dg,
then do a .DataBind. The columns are automatically created.
Question: How can I dynamically change the width's of these columns?
Thanks in advance.

Hello,
Please pardon my ignorance as I'm sure this is easy to do. I have a datagrid
where I want to let the user delete columns. I added a context menu to the
datagrid that has a delete option. If the user right clicks on a column
heading can I highlight that column and then delete it? I'm not exactly sure
how to highlight it or figure out what column has been clicked.
In my testing so far when I use the context menu I always get the...

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
