I have multiple datagridviews on one form. I am allowing editing in the
grid, and am performing error checking.
I am validating the data, if it isn't valid, I am cancelling any other
events fired. My problem is, I am validating in grid A, if they click
in Grid B, I am popping up a message box informing them of the error,
but if they click ok on the message box, and then click in grid B
again, it goes on. The following is a code...

Hello,
I am populating a datagridview from a datatable and filtering the number of
rows with a dataview object. Is there a way to retrieve the rows displayed
by the datagridview into a separate datatable without having to loop through
each column in the datagridview? Or is there a way to retrieve the rows from
the original datatable filtered by the dataview into a separate table? I
only want to copy the rows from the main table that...

Hello,
Following an example at
http://www.vb-tips.com/dbpages.aspx?IA=DG (by Cor Lightert and Ken Tucker)
on binding a dataRelation to a Datagridview for sqlClient, I was able to
view rows in datagridview2 that corresponded to a selected row in
datagridview1. Great article/example.

Can I use a bound ComboBox for both browsing and editing?
I'm working on a small, standalone database application using Visual
C#.NET 2003 and an Access data file.
In order to keep the number of different screens down to a minimum,
I'm trying to use the same Windows Forms for both browsing and for
updating. This works fine for TextBoxes, but I'm running into
problems with my DropDownLists (ComboBoxes).

On my form I have a datagridview that's bound to a table on my DB.
When I run the app then click on a column header to sort, it sorts
just fine. But my problem is a result of that sort.
Even though the view has been sorted, it's underlying data isn't.
After sorting I'm trying to get the datarow I just doubleclicked on.
The problem is it's returning the pre sorted row. That is, the row
that was there before I sorted the column.

Hi,
I have bound a DataView to a DataGridView using
this.dataGridView1.DataSource = new
DataView(this.dataTable1);
I allow for sorting of the datagridview using clicks on the headers.
Later on I need to determine the content of any selected cell or row
in that datagridview once a button has been pressed.

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
