Accessing dataGridView Column value on column Checked/Unchecked

[sk27ahmed]

Hi

Any one can show me how to access datagridview column value on column checked unchecked.
I create one column in datagridview of type checkbox,and on button click i write code to select all rows in the datagridview.
The code for select all is

for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
dataGridView1.Rows[i].Cells[0].Value = true;
}
Now i want to take second column cell values of all rows either in array/arraylist on another button click.

uptil now I am unable to write any code for it.
Thank You
