我有以下asp.net頁面如何顯示數據庫信息（evals？標籤？文本？）
<form id="form1" runat="server">
<asp:Button id="display_button" runat="server" Text="Display" OnClick="Button1_Click" />
<asp:Button id="edit_button" runat="server" Text="Edit" OnClick="Button2_Click" />
<asp:Button id="save_button" runat="server" Text="Save" OnClick="Button3_Click" Visible="false" />
<br />
<asp:Label ID="Label1" runat="server"></asp:Label>
<br />
<asp:MultiView id="MultiView1" runat="server" ActiveViewIndex="0">
<asp:View id="View1" runat="server">
<asp:FormView id="view_program" runat="server">
<ItemTemplate>
<tr>
<td class="add_border_bold" nowrap">Status</td>
<td width="100%" class="add_border">
<img src="images/<%# Eval("status").ToString().Trim() %>_light_16.gif" alt="status" />
</td>
</tr>
<tr>
<td class="add_border_bold" nowrap">Short Title</td>
<td width="100%" class="add_border">
<%# Eval("short_title") %>
</td>
</tr>
</ItemTemplate>
</asp:FormView>
</asp:View>
<asp:View id="View2" runat="server">
<asp:FormView id="edit_program" runat="server">
<ItemTemplate>
<tr>
<td class="add_border_bold"nowrap">Status </td>
<td width="100%" class="add_border">
<asp:DropDownList id="p_status" runat="server"></asp:DropDownList>
</td>
</tr>
<tr>
<td class="add_border_bold" nowrap">Short Title</td>
<td width="100%" class="add_border">
<asp:TextBox runat="server" id="short_title" />
</td>
</tr>
</ItemTemplate>
</asp:FormView>
</asp:View>
</form>

基本上後面的下面的代碼，它是一個頁面都顯示這些字段，然後點擊按鈕顯示所有這些字段的可編輯版本。我的問題是，我是否應該像現在一樣顯示所有信息，並帶有evals？或者我應該切換到標籤，文字還是其他東西？我想知道，我太過遙遠，不得不撤消大量的工作。
最終會出現在這個頁面上的大量字段，所有類型從複選框到下拉到多行文本框，所以我想確保我選擇最適合顯示所有這些不同類型數據的路徑，即使在這個例子中，我只顯示小文本信息。
