打开和打开问题在ContextMenuStrip中关闭事件 [英] Problem with opening & closing events in ContextMenuStrip

问题描述

我制作了一个MenuStrip和ContextMenuStrip，在MenuStrip中，我有一个exitToolStripMenuItem1，并且我的表单中有按钮，当我单击按钮时，在右键单击中显示exitToolStripMenuItem1，但是我的exitToolStripMenuItem1在MenuStrip中隐藏了，我该如何解决开幕式ContextMenuStrip的关闭事件?

i made a MenuStrip and ContextMenuStrip,in MenuStrip i have a exitToolStripMenuItem1 and i have button in my form,when i click on button exitToolStripMenuItem1 was show in Right click but my exitToolStripMenuItem1 hide from MenuStrip,how can i solve it with opening & closing events of ContextMenuStrip?

namespace Menu
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            ContextMenuStrip.Items.Add(exitToolStripMenuItem1);
        }

        private void ToolStripMenuItem1_Click(object sender, EventArgs e)
        {
            ToolStripMenuItem itmCurrent = (ToolStripMenuItem)sender;

            switch (itmCurrent.Name)
            {
                case "exitToolStripMenuItem1":

                    System.Windows.Forms.DialogResult interactionResult;
                    interactionResult = MessageBox.Show("Are you sure you want to exit?", "Exit", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2);

                    if (interactionResult == System.Windows.Forms.DialogResult.Yes)
                        Application.Exit();

                    break;
            }
        }
    }
}

推荐答案

您需要做的是在设计中包括toolstripmenuitem.

将属性设置为可见的false和已启用的false

单击时，将visible和enabled属性设置为true.

适用于菜单条和上下文菜单条

What you need to do is to include the toolstripmenuitem in the design.

Set properties to visible false and enabled false

On click set the properties of visible and enabled to true.

that works for both the menu strip and the context menu strip
