Hi,
You need to provide more details, like if this is a win or a web based app.
In any case 10K of rows are a little too much, you should reduce the number
of rows. That will improve the performance al ot.

Hello,
When I create a DataTable and add 10000 rows my computer needs about
20ms. To delete 10000 rows it needs about 15ms.
When I connect the DataTable to a DataGridView it needs 3100ms to add
10000 rows and 6300ms to delete 10000 rows. That might be ok because
the control needs an update.
But when a disconnect the DataTable widht dgv.DataSoure = null it
needs 420ms to add 10000 rows and 2430ms to delete rows.
Can anyone explain what happened here and how I can modify the
DataTable so I get the performance when it is never bound to a
DataGridView?
Thanks in advance for any response
