C#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。八 ListVi ew图1 ListView控件2 属性ListView控件常用属性及说明如表1所示属性说明FullfowSkc

4、Select get; set; iI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Falsa默认为Falseo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 GridL ines get; set; 属性值：如果

5、在项及其子项的周围绘制网格线，则为True；否则为Falsa默认为Falsa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.IvStude nt.View = View.Details;this.IvStude nt.FullRowSelect = True;this .lv Stude nt.GridL ines = True;完整程序代码如
