C# Listview的ColumnWidthChanged事件不是fire？

我尝试不允许在listview中调整列的大小，但我不能 我不知道为什么listview的ColumnWidthChange事件不是fire 我尝试调试，但发现方法listView1\u的列宽从未改变

在Form1.Designer.cs中：

    partial class Form1
{
    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.ComponentModel.IContainer components = null;

    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }

    #region Windows Form Designer generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InitializeComponent()
    {
        this.listView1 = new System.Windows.Forms.ListView();
        this.columnHeader1 = ((System.Windows.Forms.ColumnHeader)(new System.Windows.Forms.ColumnHeader()));
        this.columnHeader2 = ((System.Windows.Forms.ColumnHeader)(new System.Windows.Forms.ColumnHeader()));
        this.SuspendLayout();
        // 
        // listView1
        // 
        this.listView1.Columns.AddRange(new System.Windows.Forms.ColumnHeader[] {
        this.columnHeader1,
        this.columnHeader2});
        this.listView1.Location = new System.Drawing.Point(13, 103);
        this.listView1.Name = "listView1";
        this.listView1.Size = new System.Drawing.Size(259, 97);
        this.listView1.TabIndex = 0;
        this.listView1.UseCompatibleStateImageBehavior = false;
        this.listView1.View = System.Windows.Forms.View.Details;
        this.listView1.ColumnWidthChanging += new System.Windows.Forms.ColumnWidthChangingEventHandler(this.listView1_ColumnWidthChanging);
        // 
        // columnHeader1
        // 
        this.columnHeader1.Text = "ID";
        this.columnHeader1.Width = 0;
        // 
        // columnHeader2
        // 
        this.columnHeader2.Width = 200;
        // 
        // Form1
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(284, 262);
        this.Controls.Add(this.listView1);
        this.Name = "Form1";
        this.Text = "Form1";
        this.ResumeLayout(false);

    }

请帮帮我！！！！！！T\T

看起来您正在使用“隐藏”的第一列来携带一个值。这正是“标记”属性的用途

var listViewItem = listView1.Items.Add(rowData);
listViewItem.Tag = id;

然后，您可以在以后检索：

var selectedListViewItem = listView1.Items.SelectedItems[0];
var selectedID = (int)selectedListViewItem.Tag;

Windows中的一些设置可能会影响ColumnWidthChange事件的触发，以及解决此问题的方法。但是如果你不需要的话，我建议你不要去那里。

对我来说很好。发布完整的代码，复制问题。这是完整的我的代码。这很简单，但事件不是Fire。这不能是完整的代码片段，我要的是复制粘贴并运行以查看问题的代码。你是否将此事件附加到控件？例如，通过表单设计器，或通过某种方式，例如

listView1.ColumnWidthChanging+=listView1\u ColumnWidthChanging

？如果未将该事件作为处理程序添加到control.code以复制粘贴并运行以查看问题，则该事件的存在不会起任何作用。该事件为空。它什么都不是。调试时，断点从不进入方法listView1\u

var selectedListViewItem = listView1.Items.SelectedItems[0];
var selectedID = (int)selectedListViewItem.Tag;
