ListView.HeaderStyle 属性

获取或设置列标头样式。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public Property HeaderStyle As ColumnHeaderStyle
用法
Dim instance As ListView
Dim value As ColumnHeaderStyle

value = instance.HeaderStyle

instance.HeaderStyle = value

public ColumnHeaderStyle HeaderStyle { get; set; }

public:
property ColumnHeaderStyle HeaderStyle {
    ColumnHeaderStyle get ();
    void set (ColumnHeaderStyle value);
}

/** @property */
public ColumnHeaderStyle get_HeaderStyle ()

/** @property */
public void set_HeaderStyle (ColumnHeaderStyle value)

public function get HeaderStyle () : ColumnHeaderStyle

public function set HeaderStyle (value : ColumnHeaderStyle)

属性值

ColumnHeaderStyle 值之一。默认为 Clickable。

异常

异常类型	条件
InvalidEnumArgumentException	指定的值不是 ColumnHeaderStyle 值之一。

备注

HeaderStyle 属性允许您指定当 ListView 控件的 View 属性设置为 Details 且 ListView 控件具有在 ListView.ColumnHeaderCollection 中指定的 ColumnHeader 对象时，要显示的列标头的类型。ColumnHeader 对象定义 ListView 控件中显示的列。各列用于显示 ListView 中的各项的子项信息。

可通过 HeaderStyle 属性指定列标头是否可见；或者，在列标头可见的情况下，指定它们是否将用作可单击的按钮。如果将 HeaderStyle 属性设置为 ColumnHeaderStyle.None，则不会显示列标头，但是仍然会在列中排列 ListView 控件的项和子项。如果 HeaderStyle 属性设置为 ColumnHeaderStyle.Clickable，则列标头就像按钮一样，用户可以单击它来执行操作，例如，使用所单击的列中的项作为键，对 ListView 控件中的项进行排序。可在 ColumnClick 事件的处理程序中实现此行为。如果 HeaderStyle 属性设置为 ColumnHeaderStyle.Nonclickable，则显示列标头，但不能单击它。

示例

下面的代码示例演示一个允许选择多项的 ListView。该示例演示如何设置 HideSelection 和 HeaderStyle 属性。它还演示了 ColumnHeader.Text、ColumnHeader.TextAlign 和 ColumnHeader.Width 属性。若要运行此示例，请将以下代码粘贴到一个窗体中，该窗体包含一个名为 ListView1 的 ListView 对象和一个名为 TextBox1 的 TextBox。从窗体的构造函数或 Load 事件处理程序中调用 InitializeListView 方法。

' This method adds two columns to the ListView, setting the Text 
' and TextAlign, and Width properties of each ColumnHeader.  The 
' HeaderStyle property is set to NonClickable since the ColumnClick 
' event is not handled.  Finally the method adds ListViewItems and 
' SubItems to each column.
