}

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
    if (dataGridView1.Columns[e.ColumnIndex].Name == "Name")
    {

    }
}

Answer 1

I assume Name is the name of DataGridViewCheckBoxColumn

private void dataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
    if (dataGridView1.Columns[e.ColumnIndex].Name == "Name")
    {
        var isChecked = dataGridView1[e.ColumnIndex, e.RowIndex].Value as bool? ?? false;
        //rest of logic
    }
}

this is the simplest and safest way.

To iterate through all cells in row use this code:

DataGridViewRow row = dataGridView1.Rows[e.RowIndex];
foreach (DataGridViewCell cell in row.Cells)
{
   object value = cell.Value;
}

Maybe you can use the FindControl() to get the state of checkbox:

CheckBox cbName = (CheckBox)dataGridView1.Columns[e.ColumnIndex].FindControl("cbName");
checkState = cbName.CheckState.toString();

or

isChecked = cbName.Checked;
