我有,我想通過單選按鈕list.and選擇一個選項後,顯示從數據庫的一個記錄,並單擊下一步按鈕旁邊記錄loads.this一個項目是我的html代碼:如何通過單選按鈕列表顯示圖片?
<table style ="width :800px">
<tr>
<td style="width: 100px">
<asp:Image ID="Image1" runat="server" ImageUrl="~/images/stdents12.jpeg" /></td>
</tr>
<tr>
<td style="width: 100px">
<table style="width: 950px" id="TABLE1" onclick="return TABLE1_onclick()">
<tr>
<td colspan="8" style="color: white; height: 21px; background-color: #3366ff">
<asp:Label ID="Label1" runat="server" Font-Bold="True" Text="Test No :" Width="82px"></asp:Label>

</tr>
<tr>

Width="70px" />
</td>
</tr>
</table>
</td>
</tr>
<tr>
<td style="background-color: silver;" class="style1">
</td>
</tr>
</table>
,這是我的代碼隱藏頁:
void Page_PreRender(object sender, EventArgs e)
{
OnlineExamEntities context = new OnlineExamEntities();
StringBuilder bldr = new StringBuilder();
bldr.AppendFormat("var Timer = new myTimer({0},{1},'{2}','timerData');", this.timerStartValue, this.TimerInterval, this.lblTimerCount.ClientID);
bldr.Append("Timer.go()");
ClientScript.RegisterStartupScript(this.GetType(), "TimerScript", bldr.ToString(), true);
ClientScript.RegisterHiddenField("timerData", timerStartValue.ToString());
/////////////////////////////
List<int> a = (List<int>)Session["QnumList"];
List<string> resulttemp = new List<string>();
int j = a[Convert.ToInt32(Session["Click"].ToString())];
var q3 = ((from c in context.questions
orderby c.QID
where c.QID == j
select c)).SingleOrDefault();
resulttemp.Add(q3.trueAns.ToString());
Session["result"] = resulttemp;
Questionlbl.Text = q3.Question1.ToString();
Image2.ImageUrl = q3.ans4.ToString();
RadioButtonList1.Items.Clear();
string ans1, ans2, ans3;
ans1 = q3.ans1.ToString();
ans2 = q3.ans2.ToString();
ans3 = q3.ans3.ToString();
RadioButtonList1.Items.Add(String.Format("<img src='{0}'>", ans1));
RadioButtonList1.Items.Add(String.Format("<img src='{0}'>", ans2));
RadioButtonList1.Items.Add(String.Format("<img src='{0}'>", ans3));
}
,當我選擇一個選項,並單擊下一步按鈕,加載另一個記錄我得到這個錯誤:
* 從檢測到有潛在危險的Request.Form值客戶端(RadioButtonList1 =「*
我調整了Validate Request =」false「,但它不起作用。
