i have a Form with two datagridViews. if i select a row in datagridView_1 then i clear the dataGridView_2 Row Items and add new items. 
Somethimes when i select a row in datagridView_1 the system crashes and i can't catch the system exeption, because its an internal crash while drawing die dataGridView. I Think it occur while trying to draw the selcted Rows of dataGridView_2.

i think i have figured out the problem:
- datagridView_2.selectedRows[0].index  = i
- when selecting an other Row on datagridView_1, the datagridView_2 get new items
- if (datagridView_2.Rows.Count < i) -->crash

the problem doesnt occur on debugging mode
Comment 2 tommy 2013-02-27 02:01:04 UTC
datagridView_2.ClearSelection(); has no effect
Comment 3 tommy 2013-02-27 02:10:01 UTC
for other people who have the problem, i have a little workaround: hust put a try catch statement in the "program.cs"
