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,
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...

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.

I'm trying to make a datagridview column to act like a datetimepicker column (C#.Net 2005). These are the behaviours that the dgv should have:
1) Initially all the cells of the dtp column should be blank unless they are filled by the user.
2) As soon as the user enters a cell, the dtp control should appear as the editing control of that cell. If there's a value in the cell beforehand, that value is set as the value of the dtp editing control...

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:

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,...
