c# listview 使用方法

c＃的ListView是Windows應用程序中經常用到；
這裏是其一個比較簡單的用法；
其中：ListView爲：eListView；
用法如下所示：

//程序初始設置其基本屬性，註釋如下，並用loadData()得到其顯示內容；
//設置eListView的基本屬性
//loadData()函數得到表項，並顯示
private void EmailForm_Load(object sender, System.EventArgs e)
{
eListView.GridLines = true ;//顯示各個記錄的分隔線 
eListView.FullRowSelect = true ;//要選擇就是一行 
eListView.View = View.Details ;//定義列表顯示的方式 
eListView.Scrollable = true ;//需要時候顯示滾動條 
eListView.MultiSelect = false ; // 不可以多行選擇 
eListView.HeaderStyle = ColumnHeaderStyle.Clickable; 

loadData();
}

//***********************得到數據集並綁定到rListView控件************/
//清空eListView
//設置表頭。
//執行數據庫查詢操作，得到表中所要顯示的數據
//數據按行綁定到eListView
/*********************************************************************/
private void loadData()
{
this.eListView.Clear();

// 針對數據庫的字段名稱，建立與之適應顯示錶頭 
eListView.Columns.Add ( "序號" , 50, HorizontalAlignment.Center ) ;
eListView.Columns.Add ( "用戶名" , 60 , HorizontalAlignment.Center ) ; 
eListView.Columns.Add ( "郵件地址" , 150 , HorizontalAlignment.Center ) ; 
eListView.Visible = true ; 


string strSql = string.Format("select name,mailbox from mail ");
DBConnection dbcon = new DBConnection();
IDataReader read = dbcon.getRead(strSql);
int i =0;
while(read.Read())
{
i ++;
ListViewItem Item = new ListViewItem ( ) ; 
Item.SubItems.Clear ( ) ; 
Item.SubItems[0].Text = i.ToString() ;
Item.SubItems.Add ( read.GetString(0)) ; 
Item.SubItems.Add ( read.GetString(1)) ;
eListView.Items.Add ( Item ) ;
}
dbcon.close();//關閉數據庫鏈接 
}

通過以上就可以得到相應的數據，並顯示到ListView中；

以下函數是對ListView雙擊取數據的一個例子：

//依據事件索引和對應的列數，把相關的內容對應的顯示在相關TextBox控件中
private void eListView_SelectedIndexChanged(object sender, System.EventArgs e)
{
if(this.eListView.SelectedItems.Count >0)
{
this.tbName.Text = eListView.SelectedItems[0].SubItems[1].Text;
this.tbEmail.Text = eListView.SelectedItems[0].SubItems[2].Text;
}

}
