这篇文章介绍了如何在Windows用户控件UMenuButton中实现鼠标进入、离开和点击事件的响应，并着重展示了如何设置按钮图标和文本。同时，通过示例代码展示了如何调用OnClick方法和处理ImageBtnImg和lblBtnText的点击事件。

[DefaultEvent("Click")]
public partial class UMenuButton : UserControl
{
    public UMenuButton()
    {
        InitializeComponent();
    }

    /// <summary>
    /// 按钮图标
    /// </summary>
    public Image BtnImg
    {
        get { return pbImg.Image; }
        set
        {
            pbImg.Image = value;
        }
    }

    /// <summary>
    /// 按钮文本
    /// </summary>
    public string BtnText
    {
        get { return lblBtnText.Text; }
        set
        {
            lblBtnText.Text = value;
        }
    }

    protected override void OnMouseEnter(EventArgs e)
    {
        base.OnMouseEnter(e);
        this.BackColor= Color.FromArgb(88, 116, 216);
    }

    protected override void OnMouseLeave(EventArgs e)
    {
        base.OnMouseLeave(e);
        this.BackColor = Color.FromArgb(45, 50, 116);
    }

    protected override void OnMouseClick(MouseEventArgs e)
    {

        base.OnMouseClick(e);
        this.BackColor = Color.FromArgb(88, 116, 216);

    }

    private void lblBtnText_Click(object sender, EventArgs e)
    {
        this.OnClick(e);
    }

    private void pbImg_Click(object sender, EventArgs e)
    {
        this.OnClick(e);
    }

    private void lblBtnText_MouseEnter(object sender, EventArgs e)
    {
        OnMouseEnter(e);
    }

    private void pbImg_MouseEnter(object sender, EventArgs e)
    {
        OnMouseEnter(e);
    }
}
