我想在UserControl中创建一个自定义按钮...就像悬停动画一样。但在用户控制中它不会让我执行事件？！
编辑：我尝试将其从用户控件中删除，但这并没有改变任何内容......
我的代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Title_Bar : UserControl
{
public Title_Bar()
{
InitializeComponent();
}
private void cross_idle_MouseEnter(object sender, EventArgs e)
{
cross_hover.Show();
}
private void cross_hover_MouseLeave(object sender, EventArgs e)
{
cross_hover.Hide();
}
private void max_idle_MouseEnter(object sender, EventArgs e)
{
max_hover.Show();
}
private void max_hover_MouseLeave(object sender, EventArgs e)
{
max_hover.Hide();
}
private void min_idle_MouseEnter(object sender, EventArgs e)
{
min_hover.Show();
}
private void min_hover_MouseLeave(object sender, EventArgs e)
{
min_hover.Hide();
}
private void cross_hover_Click(object sender, EventArgs e)
{
this.ParentForm.Close();
}
}
}

我已放入所有图片框，但没有任何反应！
答案 0 :(得分：1)
this.cross_hover.Visible设置为false，调用Show不会更改该值。因此，PictureBox永远不会显示。
不要拨打Show()，而是将Visible设置为true：
private void cross_idle_MouseEnter(object sender, EventArgs e)
{
this.cross_hover.Visible = true;
}
