无法更改datagridview中的图像按钮

public class DataGridViewImageButtonColumn : DataGridViewButtonColumn
{
    public DataGridViewImageButtonColumn()
    {
        this.CellTemplate = new DataGridViewImageButtonCell();
    }
}

public class DataGridViewImageButtonCell : DataGridViewButtonCell
{
    protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates elementState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)
    {
        // 在这里绘制自定义的图像按钮
        // 可以使用Graphics对象绘制图像、文本等

        base.Paint(graphics, clipBounds, cellBounds, rowIndex, elementState, value, formattedValue, errorText, cellStyle, advancedBorderStyle, paintParts);
    }
}

DataGridViewImageButtonColumn imageButtonColumn = new DataGridViewImageButtonColumn();
dataGridView.Columns.Add(imageButtonColumn);
