Controls from placeholder cannot be accessed - c#

I have generated an ASP.NET C# website with the visual studio 2013 wizard in order to get the authentication code and add it to my web app.
I have copied all files and everything looks fine except one thing...
the RegisterExternalLogin.cs file gives me an error in my web, but in the generated sample it works and I don't know why.
This is the error:
RegisterExternalLogin.aspx.cs(65,17,65,25): error CS0103: The name 'userName' does not exist in the current context
RegisterExternalLogin.aspx.cs(82,55,82,63): error CS0103: The name 'userName' does not exist in the current context

I solved the problem...
I had to wrap the entire codebehind in a namespace
QuoteHD.Account
{
}

This control is for login form and i just cant get the values from input boxes because event don't trigger. One idea was to make AJAX post to static method but after that i cant make new session with this variables.
I try everything and this button just doesn't fire the event. I don't know what to do next, can you help me.
Ok after one more day of struggle, i manage to make a little walk around path:
In the first step i made a Button to fire event (javascript function) and make cookie, after that i make click event for actual asp:Button :
<script type="text/javascript">
function LoginClicked() {
var inputEmail = $("#txtEmail").val();
var inputPass = $("#txtPassword").val();
if(inputEmail != "" && inputPass != ""){
var userSet = inputEmail + "&" + inputPass;
setCookie("UserSettings", userSet, 1);
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*1*60*1000));
var expires = "expires=" + d.toGMTString();
document.cookie = cname+"="+cvalue+"; "+expires;
}
$("#ctl00_UserLogin_btnLogon").click();
}
}
</script>
And here is the buttons:
<asp:Panel runat="server" ID="panekl">
<asp:Button runat="server" ID="btnLogon" UseSubmitBehavior="false" CssClass="no-display" ></asp:Button>
</asp:Panel>
<button class="login-btn" id="btnLogon1" name="btnLogon1" onclick="LoginClicked()">
<i class="fa fa-paper-plane"></i><MultiLanguage:MultiLanguageLiteral ID="MultiLanguageLiteral4" runat="server" Resource="1270" />
And in the back end, i get the cookie, split it, and check for validation:
public void btnLogon_Click()
{
if (LoginSet == false )
{
string[] txtSome = Request.Cookies["UserSettings"].Value.Split('&');
if (Request.Cookies["UserSettings"] != null && txtEmailVal != "" && txtPassword != "")
{
txtEmailVal = txtSome[0].Trim();
txtPassword = txtSome[1].Trim();
}
String[] RemoteAddr = Request.ServerVariables.GetValues("REMOTE_ADDR");
if (RemoteAddr.Length <= 0)
return;
LoginDB oLoginDb = new LoginDB(txtEmailVal, txtPassword, true, RemoteAddr[0].ToString());
oLoginDb.Database = new SQLDatabase(Convert.ToString(ConfigurationManager.ConnectionStrings["dbConnectionString"].ToString()));
try
{
if (oLoginDb.Authenticate(ConfigurationManager.AppSettings["SecKeyIni"].ToString(), ConfigurationManager.AppSettings["SecKeySec"].ToString()))
{
Session["IdUserLogin"] = txtEmailVal;
_loginSet = true;
HttpCookie myCookie = new HttpCookie("UserSettings");
myCookie.Expires = DateTime.Now.AddDays(-1d);
Response.Cookies.Add(myCookie);
Label1.Text = "submit button is press";
}
else
{
_loginSet = false;
}
}
catch (Exception Exception)
{
Context.Trace.Warn(Exception.Message);
Global.ErrorMessage(Exception.Message, Context);
_loginSet = false;
}
}
}
This was the only way i figured out to get values from the control.

Asyncupload control of AjaxControlToolkit

I am using asyncupload control of AjaxControlToolkit and I want to check the file to be uploding is already exists or
not on server.
How we can do this?
Please help me out.
<!-- Client side code for control-->
<script>
function uploadError(sender, args) {
//document.getElementById('lblStatus').innerText = args.get_fileName(), "<span style='color:red;'>" + args.get_errorMessage() + "</span>";
}
function StartUpload(sender, args) {
var nodeSelectedText = document.getElementById('<%=lblFileLocation1.ClientID%>').innerHTML;
if (nodeSelectedText == "") {
$("#msgMissingSelection").dialog("open");
args.set_cancel(true);
}
else {
return true;
}
}
function UploadComplete(sender, args) {
var hdnFieldVal = document.getElementById('<%=hdnField.ClientID%>');
if(hdnFieldVal.value == "1")
{
$("#msgFileUploadExists").dialog("open");
}
else
{
$("#msgFileUpload").dialog("open");
}
}
</script>
<!-- Control Code in aspx-->
<tr>
<td></td>
<td>
<cc1:AsyncFileUpload ID="FileUpload2" Width="265px" runat="server"

</asp:Label>
<asp:HiddenField ID="hdnField" runat="server" value=""/>
</td>
</tr>
//.CS Code for ayncupload control
protected void AsyncFileUpload1_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{
string filePath="C:\Documents\temp.txt"
if(File.Exists(filePath))
{
hdnField.value="1";//Not able to access this value
}
}
Thanks!!
you just need to set your hidden field value at client side script.
See I have made little changes in your server side code:
protected void AsyncFileUpload1_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{
string filePath = "C:\\Documents\\temp.txt";
string hiddenValue = "0";
if (File.Exists(filePath))
{
hiddenValue = "1";
}
//This script will set required value for hidden field.
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "SetHiddenField", String.Format("top.$get('{0}').value = '{1}'", hdnField.ClientID, hiddenValue), true);
}
Make changes in your script location as follow:
<ajaxToolkit:ToolkitScriptManager runat="Server" EnablePartialRendering="true" ID="ScriptManager1" />
<script>
function uploadError(sender, args) {
//document.getElementById('lblStatus').innerText = args.get_fileName(), "<span style='color:red;'>" + args.get_errorMessage() + "</span>";
}
function StartUpload(sender, args) {
var nodeSelectedText = document.getElementById('<%=lblFileLocation1.ClientID%>').innerHTML;
if (nodeSelectedText == "") {
$("#msgMissingSelection").dialog("open");
args.set_cancel(true);
}
else {
return true;
}
}
function UploadComplete(sender, args) {
var hdnFieldVal = document.getElementById('<%=hdnField.ClientID%>');
if(hdnFieldVal.value == "1")
{
$("#msgFileUploadExists").dialog("open");
}
else
{
$("#msgFileUpload").dialog("open");
}
}
</script>
Check if the file exists using the following:-
File.Exists
You can compare based on the filename.

Get Updated Value of a UserControl TextBox within a ListView

I have a page SendResults.aspx that holds a button and a ListView with ItemTemplate set to a user control (3 labels and 2 textboxes) that gets it's data from a matching object.
On Page_Load I fill the List with data (this works well).
When the button is clicked I want to take the user input in the user-control's textboxes and do something with it.
However I always get the initial value and not the updated one.
Here is the code:
The user-control "MatchControl.ascx"
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="MatchControl.ascx.cs" Inherits="TotoMondeal.Controls.MatchControl" %>
<div>
<asp:Image ID="Team1FlagImage" runat="server" />
<asp:Label ID="Team1Label" runat="server" Width="150px"></asp:Label>
<asp:TextBox ID="Team1TextBox" runat="server" MaxLength="2" TextMode="Number" Width="50px" AutoPostBack="true" OnTextChanged="Team1TextBox_TextChanged"></asp:TextBox>
<asp:Label ID="Colon" runat="server" Font-Size="XX-Large" Text=":"></asp:Label>
<asp:TextBox ID="Team2TextBox" runat="server" MaxLength="2" TextMode="Number" Width="50px"></asp:TextBox>
<asp:Label ID="Team2Label" runat="server" Width="150px"></asp:Label>
<asp:Image ID="Team2FlagImage" runat="server" />
</div>
The user-control code-behind:
public partial class MatchControl : System.Web.UI.UserControl
{
public Match Match
{
get
{
object obj = ViewState["Match"];
return (obj == null) ? new Match() : (Match)obj;
}
set
{
ViewState["Match"] = value;
}
}
public string Team1Score
{
get { return Team1TextBox.Text; }
set { Team1TextBox.Text = value; }
}
public string Team2Score
{
get { return Team2TextBox.Text; }
set { Team2TextBox.Text = value; }
}
protected void Page_Load(object sender, EventArgs e)
{
Team1Label.Text = Match.Team1Name;
Team2Label.Text = Match.Team2Name;
Team1TextBox.Text = Match.Team1Score.ToString();
Team2TextBox.Text = Match.Team2Score.ToString();
Team1TextBox.Enabled = Match.EnableTextBox;
Team2TextBox.Enabled = Match.EnableTextBox;
Team1FlagImage.ImageUrl = #"~/FlagImages/" +Match.Team1Name + ".png";
Team2FlagImage.ImageUrl = #"~/FlagImages/" + Match.Team2Name + ".png";
}
protected void Team1TextBox_TextChanged(object sender, EventArgs e)
{
TextBox textBox = sender as TextBox;
if (textBox != null)
{
try
{
Match updatedMatch = new Match()
{
MatchId = Match.MatchId,
MatchDate = Match.MatchDate,
Result = Match.Result,
Team1Name = Match.Team1Name,
Team1Score = Convert.ToInt32(textBox.Text),
Team2Name = Match.Team2Name,
Team2Score = Match.Team2Score,
EnableTextBox = Match.EnableTextBox
};
Match = updatedMatch;
}
catch (Exception ex)
{
throw ex;
}
}
}
The SendResults.aspx:
<%# Page Title="שלח תוצאות" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="SendResults.aspx.cs" Inherits="TotoMondeal.SendResults" %>
<%# Register TagPrefix="TOTO" TagName="MatchControl" Src="~/Controls/MatchControl.ascx" %>

<div class="jumbotron">
<asp:ListView ID="TodayMatchesList" runat="server">

</ItemTemplate>
</asp:ListView>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
</div>
</asp:Content>
the SendResults code-behind:
public partial class SendResults : Page
{
protected void Page_Load(object sender, EventArgs e)
{
List<Match> matches = new List<Match>();
matches = Queries.GetTodayMatches(DateTime.Now);
foreach (Match match in matches)
{
match.EnableTextBox = true;
}
this.TodayMatchesList.DataSource = matches;
this.TodayMatchesList.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
for (int i = 0; i < TodayMatchesList.Items.Count; i++)
{
MatchControl match = (MatchControl)TodayMatchesList.Items[i].FindControl("MatchControl");
TextBox textBox = (TextBox)match.FindControl("Team1TextBox");
string txt = textBox.Text;
}
}
}
The problem is that in this line:
TextBox textBox = (TextBox)match.FindControl("Team1TextBox");
string txt = textBox.Text;
I always get the initial value from the database, and not the user updated input.
Please help I'm new at this.
Your List is getting overwritten every time you post back. Add this in Page_Load for SendResults
if ( !Page.IsPostBack )
{
List<Match> matches = new List<Match>();
matches = Queries.GetTodayMatches(DateTime.Now);
...etc...
}
In addition to checking IsPostBack you need to handle saving your control properties in the ViewState. As suggested here: User control (ascx) and properties
Example from post:
public string Title {
get { return Convert.ToString(ViewState["Title"]); }
set { ViewState["Title"] = value; }
}
You would do this in your control class.

Implement LDAP in ASP.net (C#) MVC4

I originally got this working on a ASP.net application (non MVC) but now that I have to change over to MVC I do not know how to adapt my old code. For reference, I am using the stock website you get for the application (needed to be quick and dirty) and I am also sewing in Zurb's Foundation framework. This is also C# based.
Here is the old way that worked:

Here was the script below (Same Page) that worked.
<script runat="server">
void Login_Click(object sender, EventArgs e)
{
string adPath = "LDAP://DC03/DC=Meowmeow,dc=com"; //Path to your LDAP directory server
Legend_Forms_Manager.LdapAuthentication adAuth = new Legend_Forms_Manager.LdapAuthentication(adPath);
try
{
if (true == adAuth.IsAuthenticated(txtDomain.Text, txtUsername.Text, txtPassword.Text))
{
string groups = adAuth.GetGroups();
//Create the ticket, and add the groups.
bool isCookiePersistent = chkPersist.Checked;
FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(1,
txtUsername.Text,DateTime.Now, DateTime.Now.AddMinutes(60), isCookiePersistent, groups);
//Encrypt the ticket.
string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
//Create a cookie, and then add the encrypted ticket to the cookie as data.
HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket);
if(true == isCookiePersistent)
authCookie.Expires = authTicket.Expiration;
//Add the cookie to the outgoing cookies collection.
Response.Cookies.Add(authCookie);
//You can redirect now.
Response.Redirect(FormsAuthentication.GetRedirectUrl(txtUsername.Text, false));

I included the following references:
~ System.DirectoryServices
I am having EXTREME difficulty finding anywhere that has any iota of consistency in a tutorial that does not date back to 2008 or so.
If you can please help me... I have everything out here and now it just needs to be translated, I think.
I added the .aspx and .cs from the old to the new, added ADConnectionString to web.config, and added tokens to the .cs and the .aspx to prevent cross-site scripting (it forced me to as per the references). You can now get to the page, fill in the info, but when you click 'Submit' it blanks the page and does nothing. Still need help.
