c# – 阻止用户调整ListView中列宽的大小?

我有一个ListView在我的Winform中有4列,名称,金钱,ID和级别.

问题是当我运行我的应用程序时,我仍然有能力搞乱列宽
并改变它们.

我搜索并发现我应该这样做:

private void listView1_ColumnWidthChanging(object sender,ColumnWidthChangingEventArgs e){ e.Cancel = true; e.NewWidth = listView1.Columns[e.ColumnIndex].Width;}

但问题是,当我调试和Ccanged列宽度时,这个事件甚至没有发射!

它为什么不开火?

我怎样才能使列宽固定?

我做了一个新的winform应用程序,以防我的旧版本出现问题,
它解雇了,但只是第一次运行应用程序..这是代码:

namespace CsharpWinformTestingStuff{ public partial class Form1 : Form { public Form1() { InitializeComponent(); listView1.ColumnWidthChanging += new ColumnWidthChangingEventHandler(listView1_ColumnWidthChanging); } void listView1_ColumnWidthChanging(object sender,ColumnWidthChangingEventArgs e) { e.Cancel = true; e.NewWidth = listView1.Columns[e.ColumnIndex].Width; } }}

这里是初始化组件,以防您可能想知道:

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.columnHeader3 = ((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.columnHeader3}); this.listView1.GridLines = true; this.listView1.Location = new System.Drawing.Point(12,12); this.listView1.Name = “listView1”; this.listView1.Size = new System.Drawing.Size(284,275); this.listView1.TabIndex = 0; this.listView1.UseCompatibleStateImageBehavior = false; this.listView1.View = System.Windows.Forms.View.Details; // // columnHeader1 // this.columnHeader1.Text = “Name”; this.columnHeader1.Width = 97; // // columnHeader2 // this.columnHeader2.Text = “Age”; this.columnHeader2.Width = 52; // // columnHeader3 // this.columnHeader3.Text = “Email”; this.columnHeader3.Width = 157; // // Form1 // this.AutoScaleDimensions = new System.Drawing.SizeF(6F,13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.ClientSize = new System.Drawing.Size(308,299); this.Controls.Add(this.listView1); this.Name = “Form1”; this.Text = “Form1”; this.ResumeLayout(false);}解决方法 您可以检查 Better ListView Express.我们已经在列上实现了AllowResize属性,这正是您所需要的.
