我試圖做一些我認爲很簡單的事情。我有2個工具條項目。在C＃visual studio 2010中不會改變面板的可見性
TEST1：ToolStripMenuItem哪些應該顯示面板 - > test_panel_1
TEST2：ToolStripMenuItem哪些應該顯示面板 - > PANEL1
test_panel_1包含按鈕 - > panel_1_button1應隱藏test_panel_1並顯示test_panel_2
PANEL1包含按鈕 - > button1這應該隱藏test_panel2然後顯示面板2
但是，當我運行代碼並單擊test1ToolStripMenuItem它顯示test_panel_1像它應該，然後當我點擊panel_1_bu tton_1它只是清除了test_panel_1，並沒有顯示test_panel_2。不管我首先點擊什麼，test2ToolStripMenuItem根本不顯示panel1。
這裏是我的代碼...
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;
}
}
}
和，不知道這會有所幫助，但...

我玩弄用戶控件的卻很少，我喜歡的方式我可以編輯和查看它們比面板好得多;但是，我不知道如何控制隱藏和顯示它們。
感謝您的幫助。我知道這一定是編碼101，但這是我還沒有完全弄清楚的。
檢查您的事件處理程序是否正在使用某些斷點。同時檢查你的面板不在彼此之上。我有時會將面板設置爲不同尋常的顏色，以便我可以清楚地看到事物，以確保事物不會意外重疊。 –
