C#中 Li st Vi ew 控 件应 用 实 例名师资料总结-精品资料欢迎下载-名师精心整理-第 1 页，共 19 页 -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。名师资料总结-精品资料欢迎下载-名师精心整理-第 2 页，共 19 页 -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 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，通常使用名师资料总结-精品资料欢迎下载-名师精心整理-第 3 页，共 19 页 -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 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
