  OnTextChanged and the events by clicking on Submit-button doesn't work fine

  Aug 31, 2012 09:32 AM|LINK

  I've have a webapplication with a Masterpage, and inside the page you have Default page,

  I've problem with aupostback by login user/password. The Login-page is a usercontrol who placed in a Placeholder (inside the Default-page). The button btnLogin is placed on the default page.

  When I click on the Login-button, I only see the DoTextChanged-event will fire and the Login-page has get the default settings again.

  in uclLogin.ascx

  1. <asp:TextBox ID="txtGebruiker" runat="server" Width="300" OnTextChanged="DoTextChanged" AutoPostBack="true"> </asp:TextBox>
  2. <asp:RequiredFieldValidator ID="valIsGebruikerOpgegeven" runat="server" ErrorMessage="De gebruikersnaam is niet opgegeven." CssClass="FailureNotification" Text="*" ControlToValidate="txtGebruiker" SetFocusOnError="true" />
  3. </asp:TableCell></asp:TableRow><asp:TableRow> <asp:TableCell Width="25%">
  4. <asp:Label ID="lblWachtwoord" runat="server" >Wachtwoord</asp:Label>
  5. </asp:TableCell><asp:TableCell Width="75%">
  6. <asp:TextBox ID="txtWachtwoord" runat="server" Width="300" TextMode="Password" OnTextChanged="change" AutoPostBack="true"> </asp:TextBox>
  7. <asp:RequiredFieldValidator ID="valIsWachtwoordOpgegeven" runat="server" ErrorMessage="Het wachtwoord is niet opgegeven." CssClass="FailureNotification" Text="*" ControlToValidate="txtWachtwoord" SetFocusOnError="true" />

  in uclLogin.ascx.cs

  1. protected void Page_Load(object sender, EventArgs e)
  2. {
  3.   if (!IsPostBack)
  4.         {
  5.               ...
  6.         Identificatie.Domeinnaam = txtDomein.Text;
  7.              Identificatie.Gebruiskersnaam = txtGebruiker.Text;
  8.         }
  9. }
  10. protected void DoTextChanged(object sender, EventArgs e)
  11. {
  12.        Identificatie.Domeinnaam = txtDomein.Text;
  13.        Identificatie.Gebruiskersnaam = txtGebruiker.Text;
  14.        Identificatie.Wachtwoord = txtWachtwoord.Text;
  15. }

  in the default.aspx:

  1. protected void btnLogin_Click(object sender, EventArgs e)
  2. {
  3.      try
  4.      {
  5.          AutenticateUser(Identificatie.Domeinnaam, Identificatie.Gebruiskersnaam, Identificatie.Wachtwoord);
  6.      }
  7.    catch (Exception ex)
  8.      {
  9.          lblError.Text = ex.Message;
  10.          lblError.Visible = true;
  11.      }
  12. }

  When I remove the AutoPostback="true", then the Login works fine. But when I Logout a I returns back to the Login page. The Login doesn't work anymore.

  What do I wrong? The Login has to do work always correct. Also when you want to login on another username.

  thanks

  you can call this on button event or call onblur event but for this you need web service password field never allow Textchange event

  for username and password remembering you can use session or cookies

  Try Cookies : 

  For Storing : 

  HttpCookie myCookie = new HttpCookie("myCookie");
  Response.Cookies.Remove("myCookie");
  Response.Cookies.Add(myCookie);
  myCookie.Values.Add("txtUserName", txtUserName.Text);
  myCookie.Values.Add("txtPassword", txtPassword.Text);

  Retreival : 

  if (HttpContext.Current.Request.Cookies["myCookie"] != null)
  {
  txtUserName.Text = HttpContext.Current.Request.Cookies["myCookie"]["txtUserName"].ToString();
  txtPassword.Text = HttpContext.Current.Request.Cookies["myCookie"]["txtPassword"].ToString();
   }

  And in which event do I declare values?

  The password and username are in the UserControl. And the Login-button is in the Default.aspx.

  How can I move the values to the default page?

  Hi WesleyN,

  I'm not sure why you would like to seperate the login button rather than merge them as a web user control. However, you can try to test my code below and change it depends on your requirement. I create all files in a folder named CustomerControl.

  uclLogin.ascx

  <%@ Control Language="C#" AutoEventWireup="true" CodeFile="uclLogin.ascx.cs" Inherits="CustomerControl_uclLogin" %>
  
  UserName:<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
  Password:<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
  <br />

  MasterPage.master

  <%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="CustomerControl_MasterPage" %>
  
  <%@ Register src="uclLogin.ascx" tagname="uclLogin" tagprefix="uc1" %>
  
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  
  <html xmlns="http://www.w3.org/1999/xhtml">
  <head runat="server">
      <title></title>
      <asp:ContentPlaceHolder id="head" runat="server">
      </asp:ContentPlaceHolder>
  </head>
  <body>
      <form id="form1" runat="server">
      <div>
              <uc1:uclLogin ID="uclLogin1" runat="server" />
          <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">        
              
          
          </asp:ContentPlaceHolder>
      </div>
      </form>
  </body>
  </html>

  Default.aspx file

  <%@ Page Title="" Language="C#" MasterPageFile="~/CustomerControl/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="CustomerControl_Default" %>
  
  <%@ Register src="uclLogin.ascx" tagname="uclLogin" tagprefix="uc1" %>
  
  
  <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
  </asp:Content>
  <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
      <asp:Button ID="Button1" runat="server" Text="Get" 
      onclick="Button1_Click" />
      <br />
      <asp:Label ID="Label1" runat="server" Text=""></asp:Label>
      <br />
      <asp:Label ID="Label2" runat="server" Text=""></asp:Label>
  </asp:Content>

  Default.aspx.cs

  public partial class CustomerControl_Default : System.Web.UI.Page
  {
      protected void Page_Load(object sender, EventArgs e)
      {
  
      }
      protected void Button1_Click(object sender, EventArgs e)
      {
          CustomerControl_uclLogin ccuc = (CustomerControl_uclLogin)Master.FindControl("uclLogin1");
          if(ccuc != null)
          {
              TextBox username = (TextBox)ccuc.FindControl("TextBox1");
              TextBox password = (TextBox)ccuc.FindControl("TextBox2");
              if (username != null)
              {
                  Label1.Text = username.Text;
              }
              if (password != null)
              {
                  Label2.Text = password.Text;
              }            
          }
      }
  }

  Sage Gu,

  Thank you very much!

  This is a solution what I'm searching for.

  I've used a private control FAddress. And this control has everytime a different coat of the current UserControl.

  private UserControl FAddress;
  
  protected void btnLogin_Click(object sender, EventArgs e)
  {
  try
  {
  uclLogin ccuc = (uclLogin)FAddress;
  if (ccuc != null)
  {
  ...
  }
