2、stView 控件2属性ListView控件常用属性及说明如表1所示。表1    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

3、bool FullRowSelect get; set; 属性值：如果单击某项会选择该项及其所有子项，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;

4、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False。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
