Hi
Well what i'm trying to do is search text in a datagridview, i've seen
similar code around in other posts or forums, i'm implementing this by using
a Textbox, and the code in the TextChanged event, so when the user keeps
typing, the datagridview must refresh itself showing only the results that
contain the text written so far.

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.

If I populate a DataGridView with a query supplied at runtime, boolean fields
render as a CheckBox instead of just a text rendering of '0' or '1'. That is
nice sometimes, but I would like the flexibility of showing text sometimes as
well. Is there an easy way to get the text '0' or '1' instead of the
CheckBox? My DataGridView is filled in with...

I have a datagridview that users will update. When there are only a
few records the update is fine. However when they update 100-200 of
the rows the udpate can take 2+ Mins.
Is this normal performance, as the datagridview was not meant to
update this many records at once?
