【问题描述】：
我正在尝试做一些我认为相当简单的事情。我有 2 个工具条项目。
test1：应该显示面板的 ToolStripMenuItem -> test_panel_1
test2: ToolStripMenuItem 应该显示面板 -> panel1
test_panel_1 包含按钮 -> panel_1_button1 应该隐藏 test_panel_1 并显示 test_panel_2
panel1 包含按钮 -> button1 应该隐藏 test_panel2 然后显示 panel2
但是，当我运行代码并单击 test1ToolStripMenuItem 时，它会按预期显示 test_panel_1，然后当我单击 panel_1_button_1 时，它只会清除 test_panel_1 而不会显示 test_panel_2。不管我先点击什么，test2ToolStripMenuItem 根本不显示 panel1。
这是我的代码...
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace panel_test
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void panel_1_button1_Click(object sender, EventArgs e)
{
test_panel2.Visible = true;
test_panel_1.Visible = false;
}
private void test1ToolStripMenuItem_Click(object sender, EventArgs e)
{
test_panel_1.Visible = true;
panel1.Visible = false;
}
private void button1_click(object sender, EventArgs e)
{
test_panel_1.Visible = false;
test_panel2.Visible = true;
}
private void test2ToolStripMenuItem_Click(object sender, EventArgs e)
{
test_panel2.Visible = false;
panel1.Visible = true;
}
private void button1_Click_1(object sender, EventArgs e)
{
this.panel1.Visible = false;
this.panel2.Visible = true;
}
}
}
而且，不确定这是否有帮助，但是...

我玩过一些用户控件，我喜欢编辑和查看它们的方式比面板好得多；但是，我不知道如何控制隐藏和显示它们。
感谢您的帮助。我知道这一定是编码 101，但我还没有完全弄清楚。
【问题讨论】：

使用一些断点检查您的事件处理程序是否被命中。还要检查您的面板是否彼此重叠。有时我会将面板设置为不寻常的颜色，以便我可以清楚地看到事物，以确保事物不会意外重叠。
