If I understand you correctly you are saying the checkbox value does not align with the underlying data?

This may well be because the data has been updated and is 'dirty', e.g. it hasn't been committed to the datasource yet. If you add an event handler like this:

private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)
{
   if (dataGridView1.CurrentCell is System.Windows.Forms.DataGridViewCheckBoxCell)
   {
      dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
   }
}

Then that should update the datasource and you'll have the correct checkbox state when you query the cell.
