示例

下面的代码示例演示如何ListViewItem通过使用ListView.TopItem属性和ResetStyle方法来重置的子项的样式。The following code example demonstrates how to reset the style of the subitems of a ListViewItem through the use of the ListView.TopItem property and the ResetStyle method. 若要运行该示例, 请将以下代码粘贴到包含名为Button1的按钮的窗体中, 然后在窗体的构造函数或Load事件处理方法中InitializeListView调用方法。To run the example, paste the following code into a form containing a button named Button1, and call the InitializeListView method in the form's constructor or Load event-handling method.

internal:
   // Declare the Listview object.
   System::Windows::Forms::ListView^ myListView;

private:

   // Initialize the ListView object with subitems of a different
   // style than the default styles for the ListView.

      // ListView object. 
      myListView = gcnew ListView;
      myListView->Location = System::Drawing::Point( 20, 20 );
      myListView->Width = 250;
      
      // The View property must be set to Details for the 
      // subitems to be visible.
      myListView->View = View::Details;
      
      // Each SubItem object requires a column, so add three columns.
      this->myListView->Columns->Add( "Key", 50, HorizontalAlignment::Left );

注解

您可以使用此方法来重置应用到子项的字体、背景色和前景色设置。You can use this method to reset the font, background color, and foreground color settings applied to the subitem. 重置样式后, 将使用默认字体、背景色和前景色设置显示子项。When the styles are reset, the subitem is displayed using the default font, background color, and foreground color settings.
