{
    this.HandleRadioButton(sender, ToolStripDropDownDirection.AboveLeft);
}

private void radioButton2_CheckedChanged(object sender, EventArgs e)
{
    this.HandleRadioButton(sender, ToolStripDropDownDirection.AboveRight);
}

private void radioButton3_CheckedChanged(object sender, EventArgs e)
{
    this.HandleRadioButton(sender, ToolStripDropDownDirection.BelowLeft);
}

private void radioButton4_CheckedChanged(object sender, EventArgs e)
{
    this.HandleRadioButton(sender, ToolStripDropDownDirection.BelowRight);
}

private void radioButton5_CheckedChanged(object sender, EventArgs e)
{
    this.HandleRadioButton(sender, ToolStripDropDownDirection.Default);
}

private void radioButton6_CheckedChanged(object sender, EventArgs e)
{
    this.HandleRadioButton(sender, ToolStripDropDownDirection.Left);
}

private void radioButton7_CheckedChanged(object sender, EventArgs e)
{
    this.HandleRadioButton(sender, ToolStripDropDownDirection.Right);
}

// This utility method sets the DefaultDropDownDirection property.
private void HandleRadioButton(object sender, ToolStripDropDownDirection direction)
{
    RadioButton rb = sender as RadioButton;

    if (rb != null)
    {
        if (rb.Checked)
        {
            this.dropDownDirection = direction;
            this.contextMenuStrip1.DefaultDropDownDirection = direction;
        }
