当textmode=password无法从.cs文件中取出密码框的值

Question

 string logname = txtLogName.Text.Trim();
        string pwd = DB.EncryptPassword(txtPwd.Text, "MD5");
        string pwdAgain = DB.EncryptPassword(txtPwdAgain.Text, "MD5");
        string username = txtUserName.Text.Trim();
        string dpm = dplDep.SelectedValue.ToString();
        string job = txtJob.Text.ToString();
        string tel = txtTel.Text.ToString().Trim();
        string pruid = dplPru.SelectedValue.ToString();
        string bz = txtRmk.Text;        using (SqlConnection con = DB.getstrConn())
        {
            con.Open();
            using (SqlCommand cmd = con.CreateCommand())
            {
                cmd.CommandText = "proc_InsertUserInfo";
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.Add("@logname",SqlDbType.NVarChar,500).Value=logname;
                cmd.Parameters.Add("@username",SqlDbType.NVarChar,500).Value=username;
                cmd.Parameters.Add("@pwd", SqlDbType.NVarChar, 500).Value = pwd;
                cmd.Parameters.Add("@bm",SqlDbType.NVarChar,500).Value=dpm;
请问该如何取值啊

Answer 1

从txtPwd.text取出的值是空的，不知道怎么回事

Answer 2

看数据库这个字段有值没有。检查DB.EncryptPassword 转换成MD5问题

Answer 3

 <p>
            <asp:TextBox TextMode="Password" runat="server" ID="password1" />
        </p>
        <p>
            <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
        </p>
  protected void Button1_Click(object sender, EventArgs e)
        {
            string tt = password1.Text;
            Response.Write(tt);
        }可以获取到值。

我后来看了下，好像密码框的值和panel隐藏有关系，panel1隐藏后密码框取值就成了空的了

Answer 6

看着没问题呀只要password不是脚本写上去的，都应该能取到呀

Answer 7

另外，密码控件是不能直接赋值的，如
 txtPwdAgain.Text = "xxxxxxxxxx";
这样是不行的。
只能
txtPwdAgain.Attributes.Add("value","xxxx");
进行赋值，明白了吧？
