【问题描述】:
我尝试不允许在列表视图中调整列的大小,但我不能 我不知道为什么 listview 的 columnwidthchangeing 事件没有触发 我尝试调试并看到永远不会进入方法 listView1_ColumnWidthChanging
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);
}
#endregion
private System.Windows.Forms.ListView listView1;
private System.Windows.Forms.ColumnHeader columnHeader1;
private System.Windows.Forms.ColumnHeader columnHeader2;
}
在 Form1.cs 中:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void listView1_ColumnWidthChanging(object sender, ColumnWidthChangingEventArgs e)
{
if (e.ColumnIndex == 0)
{
e.Cancel = true;
e.NewWidth = 0x0;
}
}
请帮帮我!!!!!! T_T
【问题讨论】:
-
对我来说很好,发布重现问题的完整代码
-
这是我的完整代码。它很简单,但事件不会触发
-
这不可能是完整的sn-p,我要的是复制粘贴并运行查看问题的代码
-
您是否将此事件附加到控件?比如通过表单设计器,或者通过诸如
listView1.ColumnWidthChanging += listView1_ColumnWidthChanging之类的东西?如果事件的 存在 没有作为处理程序添加到控件,则不会执行任何操作。 -
复制粘贴的代码并运行查看问题。它是空的。什么都没有。当我调试时,断点永远不会进入方法listView1_ColumnWidthChanging
