中ListView控件应用实例

1、C#中ListView控件应用实例ListView控件1  功能ListView控件可以显示带图标的项列表，用户可使用该控件创建类似Windows资源管理器的用户界面。ListView控件具有4种视图模式：（1）仅文本，这是默认视图，此视图下，只显示列表项的文本；（2）带有小图标的文本，此视图下，小图标随列表项的文本同时显示；（3）带有大图标的文本，此视图下，大图标随列表项的文本同时显示；（4）报表视图，此视图下，列表项显示在多个列中。图1为List View控件。图1  ListView 控件2属性ListView控件常用属性及说明如表1所示。表1  

2、  ListView控件常用属性及说明下面对比较重要的属性进行详细介绍。（1）View属性。用于获取或设置项在控件中的显示方式。语法： public View View get; set; 属性值：View值之一。默认为LargeIcon。View的属性值及说明如表2所示。表2      View的属性值及说明（2）FullrowSelect属性。用于指定是只选择某一项，还是选择某一项所在的整行。语法： public bool FullRowSelect get; set; 属性值：如果单击某项会选择该项及其所有子

3、项，则为True；如果单击某项仅选择项本身，则为False。默认为False。说明：除非将ListView控件的View属性设置为Details，否则FullRowSelect属性无效。在ListView显示带有许多子项的项时，通常使用FullrowSelect属性，并且，在由于控件内容的水平滚动而无法看到项文本时，能够查看选定项是非常重要的。（3）GridLines属性。指定在包含控件中项及其子项的行和列之间是否显示网格线。语法： public bool GridLines get; set; 属性值：如果在项及其子项的周围绘制网格线，则为True；否则为False。默认为Fals

4、e。说明：除非将ListView控件的View属性设置为Details，否则GridLines属性无效。示例FullrowSelect属性本示例主要介绍View属性和FullrowSelect属性的使用方法，示例运行结果如图2所示。图2  FullrowSelect属性程序主要代码如下：this.lvStudent.View = View.Details;this.lvStudent.FullRowSelect = True;this.lvStudent.GridLines = True;完整程序代码如下：主程序文件完整程序代码using System;using System.Co
