單選按鈕後丟失焦點

Question

我在單選按鈕中選擇一個選項後回發問題。 選擇「是」後，它必須回發加載下面的文本框;但是，如果選擇「否」，則不能出現文本框。

我已經找到了解決方案，通過我的網站http://www.codeproject.com/Articles/17571/Maintain-focus-between-postbacks-in-ASP-NET-2-0-al（我添加了單選按鈕「CurrentControl is」的列表）的其他回發問題的解決方案，但由於超出我自己的原因，它似乎並不適用於單選按鈕。

正如我剛纔創建我的帳戶，我不能發佈圖片，但是當頁面回，焦點轉移到了最後一個文本框或下拉已關注名單。

.aspx的無線電按鈕：

<table class="dataentry"> 
    <tr> 
      <td class="column1"> 
       <asp:Label ID="lblPrevEmployed" runat="server" Text="Have you ever been employed by our company?"meta:resourcekey="lblPrevEmployed"></asp:Label> 
      </td> 
      <td class="column2"> 
       <asp:RadioButton ID="rdoPrevEmployed_Yes" runat="server" GroupName="PrevEmployed" AutoPostBack="True" OnCheckedChanged="rdoPrevEmployed_OnCheckedChanged" Text="Yes" meta:resourcekey="rbPrevEmployedYes" /> &nbsp; 
       <asp:RadioButton ID="rdoPrevEmployed_No" runat="server" GroupName="PrevEmployed" AutoPostBack="True" OnCheckedChanged="rdoPrevEmployed_OnCheckedChanged" Text="No" meta:resourcekey="rbPrevEmployedNo" /> 
       <asp:CustomValidator ID="cvPrevEmployed" runat="server" ErrorMessage="You must select either Yes or No." ValidationGroup="Group" OnServerValidate="cvPrevEmployed_ServerValidate" Display="Dynamic" meta:resourcekey="cvPrevEmployed"></asp:CustomValidator> 
      </td> 
    </tr> 
</table>

嘗試是這樣的： （我用一個單選按鈕列表，而不是單獨的單選按鈕）

一個DIV是單選按鈕列表和第二個div用於顯示與所選單選按鈕相關的描述。

此外，還會啓用通知標籤（默認情況下會禁用）通知標籤。

[HTML]

<asp:Label ID="NotifyLabel" runat="server" Text="" ForeColor="Red" Font-Bold="true"></asp:Label> 
<br /> 
<div id="SelAccTypeSelect" runat="server" style="float: left; margin-right: 20px;"> 
<asp:RadioButtonList ID="RadioButtonList1" runat="server" RepeatDirection="Horizontal" AutoPostBack="True" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged"> 
    <asp:ListItem Value="0" Text="Account Type 1" /> 
    <asp:ListItem Value="1" Text="Account Type 2" /> 
</asp:RadioButtonList> 
</div> 
<div id="SelAccTypeDesc" runat="server" style="width: 920px;"></div> 

的是含有對應於單選按鈕的值可用描述的陣列。

[代碼隱藏]

private void InitializeSelAccTypeDesc() 
{ 
SelAcctDescription[0] = "<p>This account type is for users who want to do something like this.</p>"; 
SelAcctDescription[1] = "<p>This account type is for other users who want to do something like that.</p>"; 
} 

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e) 
{ 
// get the selected account type 
AccTypeByte = Convert.ToByte(RadioButtonList1.SelectedValue.ToString()); 

     // notify the user with the value of the selected radio button 
NotifyLabel.Visible = true; 
NotifyLabel.Text = string.Format("{0} was the value selected. - ", AccTypeByte); 

// replace the html in the div with the html from the selected array element 
SelAccTypeDesc.InnerHtml = SelAcctDescription[Convert.ToInt32(AccTypeByte)]; 
} 

*注：0可能是「不」，1可能是「是」 你可以，如果周圍的NotifyLabel聲明，只顯示基於的價值添加AccTypeByte。
