2、stView 控件2屬性ListView控件常用屬性及說明如表1所示。表1    ListView控件常用屬性及說明下面對比較重要的屬性進行詳細介紹。（1）View屬性。用于獲取或設置項在控件中的顯示方式。語法： public View View get; set; 屬性值：View值之一。默認為LargeIcon。View的屬性值及說明如表2所示。表2      View的屬性值及說明（2）FullrowSelect屬性。用于指定是只選擇某一項，還是選擇某一項所在的整行。語法： public

3、bool FullRowSelect get; set; 屬性值：如果單擊某項會選擇該項及其所有子項，則為True；如果單擊某項僅選擇項本身，則為False。默認為False。說明：除非將ListView控件的View屬性設置為Details，否則FullRowSelect屬性無效。在ListView顯示帶有許多子項的項時，通常使用FullrowSelect屬性，并且，在由于控件內容的水平滾動而無法看到項文本時，能夠查看選定項是非常重要的。（3）GridLines屬性。指定在包含控件中項及其子項的行和列之間是否顯示網格線。語法： public bool GridLines get;

4、set; 屬性值：如果在項及其子項的周圍繪制網格線，則為True；否則為False。默認為False。說明：除非將ListView控件的View屬性設置為Details，否則GridLines屬性無效。示例FullrowSelect屬性本示例主要介紹View屬性和FullrowSelect屬性的使用方法，示例運行結果如圖2所示。圖2  FullrowSelect屬性程序主要代碼如下：this.lvStudent.View = View.Details;this.lvStudent.FullRowSelect = True;this.lvStudent.GridLines = True
