Enabling button when checkbox in datagridview is clicked?

Question

As the title suggests, my code is designed to detect if there's at least one checkbox checked on datagridview. If there is, a button will be enabled. If not, enabled property becomes false.

public void validatecheck(object sender, DataGridViewCellEventArgs e)
    {
        var senderGrid = (DataGridView)sender;

        if (senderGrid.Columns[e.ColumnIndex] is DataGridViewCheckBoxColumn && e.RowIndex >= 0)
        {

            foreach (DataGridViewRow row in dtgeducation.Rows)
            {
                if (Convert.ToBoolean(row.Cells[e.ColumnIndex].Value) == true)
                {
                    btnaddclass.Enabled = true;

                    break;
                }

                else
                {
                    btnaddclass.Enabled = false;
                }

            }
        }

This code still not working. Maybe I'm overlooking a essential part. Any help is greatly appreciated. :)

我将视图模型中的bool属性绑定到复选框的IsChecked属性，然后分配该属性的值以更新按钮的Enabled属性。
