获取或设置一个值，该值指示 ListBox 是否支持多列。

public:

property bool MultiColumn { bool get(); void set(bool value); };

public bool MultiColumn { get; set; }

member this.MultiColumn : bool with get, set

Public Property MultiColumn As Boolean

属性值

Boolean

如果 ListBox 支持多个列，则为 true；否则为 false。 默认值为 false。

例外

ArgumentException

多列 ListBox 的高度不能变化。

示例

下面的代码示例演示了一个简单的双列 ListBox。

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

public class Form1 : Form

{

private ListBox listBox1;

public Form1()

{

InitializeComponent();

}

[STAThread]

static void Main()

{

Application.EnableVisualStyles();

Application.SetCompatibleTextRenderingDefault(false);

Application.Run(new Form1());

}

private void InitializeComponent()

{

this.listBox1 = new System.Windows.Forms.ListBox();

this.SuspendLayout();

//

// listBox1

//

this.listBox1.FormattingEnabled = true;

this.listBox1.HorizontalScrollbar = true;

this.listBox1.Items.AddRange(new object[] {

"Item 1, column 1",

"Item 2, column 1",

"Item 3, column 1",

"Item 4, column 1",

"Item 5, column 1",

"Item 1, column 2",

"Item 2, column 2",

"Item 3, column 2"});

this.listBox1.Location = new System.Drawing.Point(0, 0);

this.listBox1.MultiColumn = true;

this.listBox1.Name = "listBox1";

this.listBox1.ScrollAlwaysVisible = true;

this.listBox1.Size = new System.Drawing.Size(120, 95);

this.listBox1.TabIndex = 0;

this.listBox1.ColumnWidth = 85;

//

// Form1

//

this.ClientSize = new System.Drawing.Size(292, 273);

this.Controls.Add(this.listBox1);

this.Name = "Form1";

this.ResumeLayout(false);

}

}

注解

多列 ListBox 项将项放入任意数量的列中，以使垂直滚动不必要。 用户可以使用键盘导航到当前不可见的列。 将 HorizontalScrollbar 属性设置为 true 显示水平滚动条，使用户能够滚动到当前未显示在可见区域中的 ListBox列。 属性的值 ColumnWidth 确定每列的宽度。
