这是HTML代码
<div id="form3">
<asp:Label ID="Label1" runat="server" Text="Enter your E-mail Id:"></asp:Label>
<asp:TextBox ID="usremailtxt" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button1" onclick="Button1_Click1" style="height: 26px"/>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Panel ID="pnlpopup" runat="server" BackColor="Red" Height="80px" Width="300px" Style="display: none" >
<table width="100%" style="border:Solid 3px #D55500; width:100%; height:100%" cellpadding="0" cellspacing="0">
<tr>
<td align="center"
style=" height:0%; color:White; font-weight:bold; font-size:larger">
Your Password Is:<asp:Label ID="pouplbl" runat="server" Text=""></asp:Label>
</td>
</tr>
</table>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
<cc2:ModalPopupExtender ID="ModalPopupExtender2" runat="server"
targetcontrolid="Button1"
popupcontrolid="pnlpopup"
dropshadow="true"
OkControlID="btnclose" >
</cc2:ModalPopupExtender>
</div>
</form>
这是 C# 代码
protected void Button1_Click1(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ConnectionString);
con.Open();
SqlCommand cmd = new SqlCommand("select password from User_detail where email_id = @email_id", con);
cmd.Parameters.AddWithValue("@email_id", usremailtxt.Text);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
pouplbl.Text = ds.Tables[0].Rows[0]["password"].ToString();
this.ModalPopupExtender2.Show();
con.Close();
}
问题是没有出现。
