ToolStrip添加自定义的DateTimePicker

直接新建一个类，代码如下:

[ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.All), DefaultEvent("ValueChanged")]
public class ToolStripDateTimePicker : ToolStripControlHost
{
    private DateTimePicker mDateTimePicker;

    public ToolStripDateTimePicker() : base(new DateTimePicker())
    {
        mDateTimePicker = DateTimePicker;
        mDateTimePicker.ValueChanged += mDateTimePicker_ValueChanged;
    }

    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    public DateTimePicker DateTimePicker
    {
        get { return (DateTimePicker) Control; }
    }

    [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]
    public override string Text
    {
        get { return string.Empty; }
        set { base.Text = string.Empty; }
    }

    public event EventHandler ValueChanged;

    private void mDateTimePicker_ValueChanged(object sender, EventArgs e)
    {
        if (ValueChanged != null)
        {
            ValueChanged(sender, e);
        }
    }
}

[ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.All), DefaultEvent("ValueChanged")]
public class ToolStripDateTimePicker : ToolStripControlHost
{
    private DateTimePicker mDateTimePicker;

    public ToolStripDateTimePicker() : base(new DateTimePicker())
    {
        mDateTimePicker = DateTimePicker;
        mDateTimePicker.ValueChanged += mDateTimePicker_ValueChanged;
    }

    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    public DateTimePicker DateTimePicker
    {
        get { return (DateTimePicker) Control; }
    }

    [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]
    public override string Text
    {
        get { return string.Empty; }
        set { base.Text = string.Empty; }
    }

    public event EventHandler ValueChanged;

    private void mDateTimePicker_ValueChanged(object sender, EventArgs e)
    {
        if (ValueChanged != null)
        {
            ValueChanged(sender, e);
        }
    }
}
