C＃聲明同一表的多個實例

Question

我有一個表需要27個單元格中的27個下拉菜單來接受用戶輸入。目前我宣佈他們所有的27個像這樣：

DropDownList DropList1 = new DropDownList(); 
DropList1.ID = "TrendList1"; 
DropList1.AutoPostBack = true; 
DropList1.SelectedIndexChanged += new EventHandler(this.Selection_Change); 
DropList1.DataSource = CreateDataSource(); 
DropList1.DataTextField = "ColorTextField"; 
DropList1.DataValueField = "ColorValueField"; 
DropList1.DataBind(); 

DropDownList DropList2 = new DropDownList(); 
DropList2.ID = "TrendList2"; 
DropList2.AutoPostBack = true; 
DropList2.SelectedIndexChanged += new EventHandler(this.Selection_Change); 
DropList2.DataSource = CreateDataSource(); 
DropList2.DataTextField = "ColorTextField"; 
DropList2.DataValueField = "ColorValueField"; 
DropList2.DataBind(); 

etc... 

但是我知道必須有比我寫的暴力代碼更好的方法。不幸的是，我是網絡編程的新手，我一直無法找到一個更好的方法來做到這一點。

任何意見表示讚賞。

問候。

var data = CreateDataSource(); 

for(x = 1; x < 28; x++) 
{ 
    DropDownList dl = new DropDownList(); 
    dl.ID = "TrendList" + x.ToString(); 
    dl.AutoPostBack = true; 
    dl.SelectedIndexChanged += new EventHandler(this.Selection_Change); 
    dl.DataSource = data; 
    dl.DataTextField = "ColorTextField"; 
    dl.DataValueField = "ColorValueField"; 
    dl.DataBind(); 
    // add it to the cell here too 
}
