This should works fine:

var value = dataGridView1[columnindex, rowindex].Value

So if you said "it doesn't work" - than just you need to provide us more information about error you got, etc.

Do you know how to debug? How do you get `columnindex` and `rowindex`? – XardasLord Aug 18 '17 at 18:52

You can try following code snippet

foreach (DataGridViewRow roow in dataGridView1.Rows)
{
   DataGridViewCheckBoxCell chkchecking = roow.Cells[0] as DataGridViewCheckBoxCell;

    if (Convert.ToBoolean(chkchecking.Value) == true)
    {
    }
}

DataGridViewCheckBoxCell checkbox = (DataGridViewCheckBoxCell)dataGridView1.CurrentCell;
bool ischecked = (bool)checkbox.EditedFormattedValue;
if (ischecked == true)
{
MessageBox.Show("True")
}

this code can get datagridview checkbox cell value
