Why is it, that in my DataGridView all columns which are not bound to
a "DataProperty" loos thier content in a couple of occasions?
This happens if:
- Underlaying DataSet.AcceptChanges()
- DataGridView bound columns -Click on header for sorting
Is there a event, that I can use to detect this situation and then

I'm creating a UserControl that uses a DataGridView in virtual mode.
It was working fine other than a few bugs. After I fixed those few
bugs, I broke it.
I have a cache of 50 records. The UserControl loads two pages of the
cache (100 records). The DataGridView.RowCount is set to 101. When I

that the RowCount needs to be updated. The DataGridView captures the
event...

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);

After searching the forums, newsgroups, and web, I cannot seem to find
a straight answer.
Is it possible to use a bounded datasource in virtual mode on a
datagridview?
I would like to have the dgv have over 1000 rows. Currently, the dvg
simply cannot handle this.
I, of course, only need 20-50 rows shown at a time.
While I will go to unbounded virtual mode if I have to, it seems like

I am using virtual mode for datagrid. After i set the rowcount property to
16000, I am receiving
datagridview 's CellValueNeeded event 16000 times for each row.
This is causing the application to hang for sometime. I am displaying only
16 rows at a time.
I am following the sample mentioned in

Marc,
Thank you very much. I have issue on implementing add row properly using
this.
User presses down arrow in last row in grid starting adding new row.
Then user changes its mind desiding that new row should not added and
presses up arrow.
DataGridView does not show this unfinished row anymore.

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.
