I need to display some internal program data in a grid to help with
debugging (just display a simple 2D table, not edit or anything else),
but I'm not an experienced database coder. AFAICS the only bindable
grid in VB2005 is the DataGridView control. But I'm struggling to get

flexible and capable control but all the features maybe get in the way
of simple use for me, at...

I've been searching forever for examples of saving data changes in a
DataGridView. There's all kinds of examples, but none really show how
to save changes. Someone please help me.
I have a Windows Forms program with a DataGridView and a BindingSource
added to a form. Here is the code I'm using to populate the grid:

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);

Hi!
I have an application in which I have some checkboxes and depending
which ones are checked those columns will show in the datagridview

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:
List<TRowtr;
tr = q.Where(r =r.Dokumnr == Dok.Dokumnr)
.OrderBy(r =r.Reanr).ToList();
Rids = new TableListCollection<TRow>(Grid.RowTable, tr);
