Hi,
I am struggling with two way databinding in WinForms and the DataGridView.
I am binding to business object classes (rather than datatables). If I
have a collection of these business objects that is the datasource of a
DataBinding that is bound to a DataGridView (WinForms) then I was expecting
that any change to the data would be reflected in the DataGridView (in other
words I was expecting the 2 way databinding to actually...

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.

I am using a DataGridView control. Using code, I would like to select a
column by column number and have it sort the Data based on the select
column.
All examples I have found, presume that a column has been selected by the
user first but this may not be the case.

The situation:
* I have a ButtonColumn in a DataGridView.
* When the user preses one of the buttons, a dialog appears.
* Based on what the user selects in the dialog, data is entered
programmatically into the the underlying cell (i.e., I'm setting Value
property of the cell based on user input, but the user is not directly
entering any data).
The problem:

New to databinding in vs2005, I always did it manually in 2003. I have no
problem loading comboboxes, and a change in that combobox changes the data in
the textboxes but I can not figure out a way to get the data in a
datagridview to change. For example 2 columns are ID and amount_paid, the
datagridview loads on form load with all ID's and amounts. How do I get it to
only bring back the selected ID. Sounds like I may need to change the SQL...

i have a small difficulties with BindingSource and dataGridView bind
db has properly opened and bind doesn't works. Unfortunately I didn't
find any good example how to connect MS Access with dataGridView and
BindSource class.
Maybe something like this:
DataTable dtResult = new DataTable();
dtResult = GetData(); // this line returns a error GetData
doesn't exists!

Hello all!
I found a solution to my original question, but there's still so much I don't understand about it, I thought I'd give this forum a try. At the very least, maybe it will help someone else who got stumped like I did.
It seems so simple... binding a DataGridView to a List<T>. These are the two general problems that I kept running into:
(1) When the data in the list updated, the data on the screen did not update.
(2) When I...

I have Winforms DataGridView whose DataSource Rids is Marc sample
TableListCollection<TRowderived from BindingList.
It is used to edit invoice rows.
If user presses Revert button, my application reads original rows from
server database:

tr = q.Where(r =r.Dokumnr == Dok.Dokumnr)
.OrderBy(r =r.Reanr).ToList();

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:

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,...
