Question

我为作者的个人信息设计了一个表格。所有文本框都获得值，并且在回发后保留其值（当我单击“保存”按钮时）但是文本框和下拉列表没有获得值，并且在回发后它们的值被清除。 HTML代码：

<table width="100%" cellpadding="0" cellspacing="0">
            <tr>
                <td  height="35" colspan="2" bgcolor="#E1DED9" style="border-left-style: 3">
                    <strong>&nbsp;Personal Information</strong></td>
            </tr>
            <tr>
                <td  height="25" bgcolor="#F3F3E9" class="style13" style="padding-left: 5px" >
                    Title:</td>
                <td height="20" bgcolor="#F3F3E9" style="padding-top: 3px; padding-bottom: 2px">
                    <asp:TextBox ID="txtTitle" runat="server" BorderColor="#DFDFC6" 
                        BorderStyle="Solid" Height="18px" Width="50px"></asp:TextBox>
                </td>
            </tr>
            <tr>
                <td bgcolor="#F3F3E9" class="style13" height="25" style="padding-left: 5px" >
                    First Name:</td>
                <td bgcolor="#F3F3E9" style="padding-top: 3px; padding-bottom: 2px">
                    <asp:TextBox ID="txtFirstName" runat="server" BorderColor="#DFDFC6" 
                        BorderStyle="Solid" Height="18px"></asp:TextBox>
                </td>
            </tr>
            <tr>
                <td  height="25" bgcolor="#F3F3E9" class="style13" style="padding-left: 5px" >

                        BorderStyle="Solid" Height="18px"></asp:TextBox>
                </td>
            </tr>
            <tr>
                <td  height="25" bgcolor="#F3F3E9" class="style13" style="padding-left: 5px" >
                    Last Name:</td>
                <td height="20" bgcolor="#F3F3E9" style="padding-top: 3px; padding-bottom: 2px">

                    <asp:RadioButton ID="rdbFemale" runat="server" Text="Female"

            <tr>

            </tr>
            <tr>

                <td height="20" bgcolor="#F3F3E9" style="padding-top: 3px; padding-bottom: 2px">
                    <asp:DropDownList ID="ddlDegree" runat="server">
                        <asp:ListItem>BS</asp:ListItem>

                        <asp:ListItem>Prof</asp:ListItem>
                    </asp:DropDownList>
                    <asp:CheckBox ID="ckbIsStudent" runat="server" Text="Student" />
                </td>
            </tr>
            <tr>
                <td  height="25" bgcolor="#F3F3E9" class="style14" >

                    </td>
            </tr></table>

代码背后：

 protected void btnFinish_Click(object sender, EventArgs e)
    {
        MembershipUser user = Membership.GetUser();
        ProfileCommon userProfile = Profile.GetProfile(user.UserName);
        userProfile.Title = txtTitle.Text;
        userProfile.FirstName = txtFirstName.Text;
        userProfile.MiddleName = txtMidName.Text;
        userProfile.LastName = txtLastName.Text;
        if (rdbMale.Checked==true)
            userProfile.Gender = "Male";
        else if (rdbFemale.Checked==true)
            userProfile.Gender = "Female";
        userProfile.Phone = txtPhone.Text;
        userProfile.Degree = ddlDegree.SelectedValue.ToString();
        if (ckbIsStudent.Checked)
            userProfile.IsStudent = true;
        else
            userProfile.IsStudent = false;
        userProfile.Save();
}

我在Page_Load（）中编写以下代码，问题解决了。

 if (!Page.IsPostBack)
        {
            txtTitle.Text = Profile.Title;
            txtFirstName.Text = Profile.FirstName;
            txtMidName.Text = Profile.MiddleName;
            txtLastName.Text = Profile.LastName;
            if (Profile.Gender == "Male")
                rdbMale.Checked = true;
            else if (Profile.Gender == "Female")
                rdbFemale.Checked = true;
            txtPhone.Text = Profile.Phone;
            ddlDegree.Text = Profile.Degree;
        }

if（！Page.IsPostBack）是我的答案！谢谢极客...
