編程方式創建字段集，OL/UL和ASP.Net李標籤，C＃

Question

我需要寫一個ASP.Net形式，將產生以下HTML：

<fieldset> 
<legend>Contact Details</legend> 
<ol> 
<li> 
<label for="name">Name:</label> 
<input id="name" name="name" class="text" type="text" /> 
</li> 
<li> 
<label for="email">Email address:</label> 
<input id="email" name="email" class="text" type="text" /> 
</li> 
<li> 
<label for="phone">Telephone:</label> 
<input id="phone" name="phone" class="text" type="text" /> 
</li> 
</ol> 
</fieldset> 

然而，這些領域是添加到表單將在運行時確定，因此我需要在運行時創建字段集，並向其添加有序列表和列表項，並根據需要添加標籤，文本框，複選框等。

我無法找到將創建這些標記的標準ASP.Net對象。

舉例來說，我想這樣做在C＃中的以下內容：

FieldSet myFieldSet = new FieldSet(); 
myFieldSet.Legend = 「Contact Details」; 
OrderedList myOrderedList = new OrderedList(); 

ListItem listItem1 = new ListItem(); 
ListItem listItem2 = new ListItem(); 
ListItem listItem3 = new ListItem(); 

// code here which would add labels and textboxes to the ListItems 

myOrderedList.Controls.Add(listItem1); 
myOrderedList.Controls.Add(listItem2); 
myOrderedList.Controls.Add(listItem3); 

myFieldSet.Controls.Add(myOrderedList); 

Form1.Controls.Add(myFieldSet); 

是否有能產生這一點，或任何標準的ASP.Net的對象是有實現相同的其他方式結果？

Answer 1

你可以試試這個：

Panel myFieldSet = new Panel(); 
myFieldSet.GroupingText= 「Contact Details」; 
HtmlGenericControl myOrderedList = new HtmlGenericControl("ol"); 

HtmlGenericControl listItem1 = new HtmlGenericControl ("li"); 
HtmlGenericControl listItem2 = new HtmlGenericControl ("li"); 
HtmlGenericControl listItem3 = new HtmlGenericControl ("li"); 

// code here which would add labels and textboxes to the ListItems 

myOrderedList.Controls.Add(listItem1); 
myOrderedList.Controls.Add(listItem2); 
myOrderedList.Controls.Add(listItem3); 

myFieldSet.Controls.Add(myOrderedList); 

Form1.Controls.Add(myFieldSet); 

Answer 2

根據上面的答案，我有這樣的情況：一個數組被證明是有用的，如下所示。注意：我在id =「ulNoTree」的aspx代碼中創建了一個無序列表。

int NumFloorsCt = 10; 
LinkButton[] rgBL; 
HtmlGenericControl[] rgLI; 

/// <summary> 
/// set up an array of LinkButtons with "li" controls 
/// - each LinkButton click is handled by the same event handler 
/// </summary> 
void SetUpLinkButtons(List<FLOOR> listFloorRecs) 
{ 
    NumFloorsCt = 10; 
    rgBL = new LinkButton[NumFloorsCt]; 
    rgLI = new HtmlGenericControl[NumFloorsCt]; 

    for (int i = 0; i < NumFloorsCt; i++) 
    { 
    rgBL[i] = new LinkButton(); 
    rgBL[i].ID = LB_ID_prefix + listFloorRecs[i].ID; 
    rgBL[i].Click += new System.EventHandler(LB_fp_Click); 
    rgBL[i].Text = listFloorRecs[i].DESCRIP; 
    rgBL[i].ToolTip = "Click here to display floor info"; 

    rgLI[i] = new HtmlGenericControl("li"); 
    rgLI[i].Controls.Add(rgBL[i]); 

    ulNoTree.Controls.Add(rgLI[i]); 
    } 
} 

/// <summary> 
/// event handler for any of the link buttons 
/// </summary> 
protected void LB_fp_Click(object sender, EventArgs e) 
{ 
    LinkButton btn = (LinkButton)(sender); 
    // do your action here 
}
