Hi,
I'm using the DataGridView in VB.NET 2.0. The DataSource is a Generic List
of a custom class0: lstMyPersonnes = New List(Of clsPersonne).
When I add a new clsPersonne to lstMyPersonnes, and rebind the
lstMyPersonnes to my DataGridView.dataSource, it shows the new record in
the DataGridView as it should be.
But when I click on a cell of that row, I suddenly got this error: "Index -1

Hello again!
I have a datagridview control on my form and am using VS.Net 2005. One
column is set up as combo box column, and when I try to set the datasource
for that combobox column at design time in the properties section of VS, I
get the error "object reference not set to instance of an object" and the
only option is to click OK.
I have not yet tried to set that datasource at runtime, but of course I
could do that. But I don't...

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...

I’ve developed forms using those nice wizards Microsoft provides. However,
I’m running into a couple of complications trying to work with the resulting

1) My user interface allows the user to fill in any combination of perhaps a

generate a list, based on an SQL statement that incorporates those QBE
fields. The...

Can anyone tell me the best way to update a dataset while it is being
edited/viewed in the DataGridView control? Is this something that
should be inserted into one of the grid's events? or should you update
after closing the grid/form, etc.?
Also, can you tell me the best book to buy that fully explains the
DataGridView control?
Thanks.

Hi All :)
I'm converting VB6 using True DBGrid Pro 8.0 to VB2005 using DataGridView.
True DBGrid has a MultipleLines property that controls whether individual
records span multiple lines. Is there an equivalent property for the
DataGridView? I have searched, but have not found one.
I would like the user to be able to see all the columns of the table on one
screen - thus eliminating the need to use the horizontal scroll bar to view...

I have DataGridView in virtual mode containing 3500 rows.
In code below, assigning to RowCount value to 3500 takes 8 seconds.
CPU usage goes high at this time.
Stepping by F11 into user code shows few celltemplate property getters and
combobox/datecombo constructor calls without database access which does not
take a lot of time.
Debug output (below) shows lot of messages Stepping over non-user code.

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,...
