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

VS2005 and I have a DataTable displayed in a DataGridView that needs custom
sorting, with the DataSource of the grid set to the DataTable and the
SortCompare event just won't fire.
Then I found this in the docs "This event occurs only when the DataSource
property is not set and the VirtualMode property value is false"
This seems really odd but may be true. I can't see what the purpose of this
event is then, how else will one use the...

I've created a custom entity class which implements IEditableObject. I have
then created a custom collection for this custom entity which naturally
inherits CollectionBase and implements IBindingList.
When I bind my custom collection to a DataGridView and started editing, it
works correctly only up to the...

I have been trying to figure out how to use DataSets, BindingSources,
DataGridViews, and XML together, but it is a challenge. I understand how
to populate a DataGridView with XML basically as:
DataSet ds = new DataSet();
ds.ReadXml(@"\usr\tmp\sample.xml");
dataGridView.DataSource = ds;
dataGridView.DataMember = "targetElement";
What I found through experimentation is that the DataMember may specify

what is the best way to use DataGridView to view data from large
database tables? Where the sql select statement might return millions
of rows?
string connectionString = GetFinancesConnString();
string sqlSelect =
"select CheckNbr, CheckDate, CheckAmt from Disbursements" ;
SqlDataAdapter adapter =
new SqlDataAdapter(sqlSelect, connectionString);

Hello:
I am binding a DataGridView with a BindingList<T>, where T is a custom
business object that implements INotifyPropertyChanged.
When you bind a DataGridView to a DataTable, it has this cool little
feature - it will not call DataTable.Rows.Add until after you leave
the DataGridView row. This is cool because it lets your user edit the
record as much as needed to get it into a valid state before actually
adding it to the DataTable.

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...

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,...
