I have made my own little chat. It it basicly a jQuery that reloads a div by inserting another .aspx site into it.
This is my .aspx site:
<%# Page Title="" Language="C#" MasterPageFile="~/holdOversigt.Master" AutoEventWireup="true"
CodeBehind="chat.aspx.cs" Inherits="HB.chat1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
var reloadtime = 3000;
function load() {
$.ajax({
url: "chat-Content.aspx",
context: document.body,
success: function (data) {
document.getElementById('chat').innerHTML = data;
setTimeout('load()', reloadtime);
}
});
}
window.onload = function () {
setTimeout('load()', reloadtime);
}
</script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h1 style="text-align: center; color: #005da3; font-weight: bold">
<strong>Chat rum</strong></h1>
<div id="chat" class="fisk" style="width: 500px; height: 500px">
</div>
<br />
<asp:TextBox ID="txbMessege" runat="server"></asp:TextBox>
<asp:Button ID="btnSend" runat="server" Text="Send" OnClick="btnSend_Click" />
</asp:Content>
THis is the site it inserts into the div:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="chat-Content.aspx.cs" Inherits="HB.chat_Content" %>
<form id="form1" runat="server">
<div>
<asp:ListBox ID="lbChat" runat="server" Rows="10" Width="400px"></asp:ListBox>
</div>
</form>
This is the sites codebehind:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace HB
{
public partial class chat_Content : System.Web.UI.Page
{
grjenie31Entities gr;
protected void Page_Load(object sender, EventArgs e)
{
gr = new grjenie31Entities();
var query = from es in gr.chats
where es.id > ((from esh in gr.chats select esh.id).Max() - 15)
orderby es.timestamps descending
select es;
List<chat> list = new List<chat>();
foreach (chat chat in query)
{
list.Add(chat);
}
for (int i = 0; i < list.Count; i++)
{
lbChat.Items.Add("[" + list[i].timestamps + "] " + list[i].personID.ToString() + ": " + list[i].besked);
}
this.lbChat.SelectedIndex = this.lbChat.Items.Count - 1;
}
}
}
I can add new lines until it loads... but when the listbox is showed on the site it give me the follow error:
The state information is invalid for this page and might be corrupted.
Anybody got any idea what i can do about it??
It seems you inserted all page content even ViewState hidden tags.
I think it's better to clear your response and write your html tags which you needed in chat.
Response.Clear();
Response.ContentType = "text/plain";
Response.Write(GetChatResult());
Response.End();

When I try to submit information from client to server, I receive Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>. I've tried most of the suggestions in the answers and they don't seem to be helping.
At the top of the .aspx page in question, adding EnableEventValidation="false" does solve the issue. However, I would like to this to remain as set to true.
I've also added (!Page.IsPostBack) in the code behind and this is still causing issues.
Could it be the jQuery timpicker that's causing the issue by inputting values based on what the user selects?
Code behind .cs
public partial class _Default : Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
var DbHelper = new DbHelper();
listOfUsers.DataSource = DbHelper.UserList();
listOfUsers.DataBind();
}
else
{
string test = listOfUsers.SelectedValue;
string time = timePicker.Text;
string reason = ReasonForRemoval.Text;
}
}
}

I've got a upload function that pops up in a diffrent window, when i've submitted i want to send infomation back to the page that the upload window opened from.
Is that possible some way with ASP.net or C#?
Or would i have to use some javascript ? and how?
My 2 pages:
news.aspx - Contains a formview with my news. and a form with some inputs in.
This is where the link to open the upload page is...
uploader.aspx - Contains my upload controller and C# code to upload.
This should send a string from my C# code back to news.aspx and put it in one of my input fields or a label, not important.
uploader.aspx file:
<form id="form1" runat="server">
<div>
Vælg en fil at uploade:<br />
<asp:FileUpLoad id="FileUpLoad1" runat="server" />
<asp:Button id="UploadBtn" Text="Upload File" OnClick="UploadBtn_Click" runat="server" Width="105px" />
<br />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
</div>
</form>
Behind Code:
using System;

using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class admin_Default2 : System.Web.UI.Page

Here is some Javascript code to create a popup window and, before the popup window closes, retrieve some information. (I will add a jQuery example in a bit)

First, I want to let everyone know that I am using an aspx engine not a Razor engine.
I have a table within a form. One of my textbox contains html tags like
</br>Phone: </br> 814-888-9999 </br> Email: </br> aaa#gmail.com.
When I go to build it it it gives me an error that says:
A potentially dangerous Request.Form value was detected from the client (QuestionAnswer="...ics Phone:<br/>814-888-9999<br...").
I tried the validation request="false" but it did not work.
I am sorry I didn't add my html code for you to look at so far. I am pulling some question up where I can edit it, if need be.

</form>
</asp:Content>
before the page is submitted you need to html encode the textbox's value, with window.escape(...)
If you need the un-escaped text on the server side then use HttpUtility.UrlDecode(...) method.
very quick sample:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="SO.WebForm1" %>
<!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>
<script>
function makeSafe() {
document.getElementById('TextBox1').value = window.escape(document.getElementById('TextBox1').value);
};
function makeDangerous() {
document.getElementById('TextBox1').value = window.unescape(document.getElementById('TextBox1').value);
}
</script>
</head>
<body>
<form id="form1" runat="server" onsubmit="makeSafe();">
<div>
<asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" Rows="10" ClientIDMode="Static"></asp:TextBox>
</div>
<asp:Button ID="Button1" runat="server" Text="Button" />
</form>
<script>
makeDangerous();
</script>
</body>
</html>
Make these changes to your code:
<script type="text/javascript">
$(document).ready(function () {
makeDangerous();
$("#freqQuestionsUserUpdateButton").click(function () {
makeSafe();
$("#updateFreqQuestionsUser").submit();
});
});
// Adding an ID attribute to the inputs you want to validate is simplest
// Better would be to use document.getElementsByTagName and filter the array on NAME
// or use a JQUERY select....
function makeSafe() {
document.getElementById('QuestionAnswer').value = window.escape(document.getElementById('QuestionAnswer').value);
};
// In this case adding the HTML back to a textbox should be 'safe'
// You should be very wary though when you use it as actual HTML
// You MUST take steps to ensure the HTML is safe.
function makeDangerous() {
document.getElementById('QuestionAnswer').value = window.unescape(document.getElementById('QuestionAnswer').value);
}
</script>
Decorate your controller action with the [ValidateInput] attribute:
[ValidateInput(false)]
[HttpPost]
public ActionResult Foo(MyViewModel model)
{
...
}
Client JavaScript:
function codificarTags()
{
document.getElementById('txtDescripcion').value = document.getElementById('txtDescripcion').value.replace(/</g,'<').replace(/>/g,'>');
}
<form id="form1" runat="server" onsubmit="codificarTags();">
Server:
protected void Page_Load(object sender, EventArgs e)
{
txtDescripcion.Text = txtDescripcion.Text.Replace(#"<", #"<").Replace(#">", #">");
}
I would suggest using the AjaxControlToolkit's HTML Editor. I'm implementing that now. If you're textbox is multi-line and big enough to accommodate HTML, why not just bump it up to an HTML editor. Your user will be happier too.
http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/HTMLEditor/HTMLEditor.aspx
Using html in textbox is not a good practice, maybe use linebreaks (Environment.NewLine) or \r\n instead of br ?
.NET Reference
Example (in C#) :
textBox1.Multiline = true;
textBox1.Text = "test" + Environment.NewLine + "test2";
I took a bit of a different approach. I wanted to use html textboxes widely across my application. I made a user control which would avoid editing the javascript every time I added a new control. My entire control is very custom but the heart of the html handling is as seen below.
The UserControl markup has some simple javascript to escape and unescape the textbox.
<script type="text/javascript">
function UnescapeControl(clientId) {
$('#' + clientId).val(window.unescape($('#' + clientId).val()));
}
function EscapeAllControls() {
var escapeControList = JSON.parse('<%= new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(EscapeControlList) %>');
for (var i = 0; i < escapeControList.length; i++)
EscapeControl(escapeControList[i]);
}
function EscapeControl(textClientId) {
document.getElementById(textClientId).value = window.escape(document.getElementById(textClientId).value);
}
</script>
<asp:TextBox ID="Txt_SavableText" CssClass="form-control" Width="100%" runat="server" ></asp:TextBox>
The code behind is responsible for escaping the controls before the post back using RegisterOnSubmitStatement and unescaping them using RegisterStartupScript after the post back.
public partial class SavableTextBox : System.Web.UI.UserControl
{
public List<string> EscapeControlList
{
get
{
if (Session["STB_EscapeControlList"] == null)
Session["STB_EscapeControlList"] = new List<string>();
return (List<string>)Session["STB_EscapeControlList"];
}
set { Session["STB_EscapeControlList"] = value; }
}
protected void Page_Load(object sender, EventArgs e)
{
if (EscapeHtmlOnPostback && !EscapeControlList.Contains(GetClientId()))
EscapeControlList.Add(GetClientId());
// When using a script manager, you should use ScriptManager instead of ClientScript.
if (EscapeHtmlOnPostback)
ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "UnescapeControl_" + GetClientId(), "UnescapeControl('" + GetClientId() + "');", true);
// Ensure we have our escape script called before all post backs containing escapable controls.
// This is like calling OnClientClick before everything.
if (EscapeControlList != null && EscapeControlList.Count > 0)
this.Page.ClientScript.RegisterOnSubmitStatement(this.GetType(), "SaveableTextBoxEscaper", "EscapeAllControls();");
}
public string Text
{
get
{
return Txt_SavableText.Text;
}
set
{
Txt_SavableText.Text = value;
}
}
public string GetClientId()
{
return Txt_SavableText.ClientID;
}
}
Now we can use it anywhere like this while setting EscapeHtmlOnPostback="True".
<%# Register TagPrefix="STB" TagName="SavableTextBox" Src="~/SavableTextBox.ascx" %>
<STB:SavableTextBox ID="Txt_HtmlTextBox" EscapeHtmlOnPostback="True" runat="server" />
Note, when we access Txt_HtmlTextBox.Text during the post back it will already be escaped for us.
I code a example like telerik Upload demo but have the following error when submit(in FF):
The connection was reset.
The demo of telerik RadUpload is here
This is the code of .aspx file:

validFile.SaveAs(Path.Combine(targetFolder,validFile.GetName()),true);
}
lblNoResults.Visible = false;

rptInvalidResults.DataBind();
}
else
{

}
}
}
Thanks!!!!
I'll go ahead and tell you with almost 100% certainty that the line that is causing this is:
var targetFolder = Server.MapPath(Commons.PAGER.UPLOAD_FOLDER);
It could be that you do not have permission to connect the server, or a variety of other issues.
To test this change "var targetFolder" to something like:
var targetFolder = #"C:\Users\j\Desktop\TEMP\"
Run this and it works perfectly, hence the idea that the path you're trying to access on the server is the problem.
Perhaps you should specify the path if possible. For example, if you are on a domain:
var targetFolder = #"\\server\Users\"
This would access that server and then the users folder therein that I have on my domain.

AND THIS ONE IS THE CASE ADMIN PAGE BASED ON THE MASTER PAGE. THERE ARE TWO BUTTONS ON THE LEFT NAVIGATION PANE THAT SHOULD LOAD A THIRD PAGE (OPENCASE OR ADDEXHIBIT) IN THE CENTRE SPACE DEPENDING ON WHICH BUTTON IS CLICKED. THE CASE ADMIN PAGE .ASPX BELOW.

ALL I WANT TO DO IS GET THE RESPECTIVE PAGES TO LOAD INSIDE THE MAIN CONTENT AREA (THE MIDDLE SECTION) WITHOUT RELOADING THE PAGE. ITS BEEN A LONG WAY COMING BUT PROVED SUCCESSFUL WITH A LOT TO LEARN BUT I JUST WANT TO KNOW HOW I CAN APPLY THIS SAME TECHNIQUE TO THE OTHER BUTTON CLICK(ADD EXHIBIT) SINCE IN THE AJAX CODE IN THE HEADER OF THE MASTER PAGE SPECIFIES THE URL ON JUST ONE PAGE. HOW DO I DO THAT FOR SUBSEQUENT PAGES THAT USE THE MASTER PAGE AND WOULD BE DOING SIMILAR ACTIONS. FOR EXAMPLE THE CASE MANAGER PAGE THAT LOOKS LIKE THIS.
<%# Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="CaseManager.aspx.cs" Inherits="Prototype4.CaseManager" %>
This is a place holder for allerts about cases to which the investigator has been assigned to.
<div style="margin-top:20px; margin-bottom:20px;">
<p class="actionButton"><asp:LinkButton ID="AllocateOfficerLinkButton" runat="server">Allocate Officer</asp:LinkButton> </p>
<p class="actionButton"><asp:LinkButton ID="ReallocateLinkButton" runat="server">Reallocate Officer</asp:LinkButton> </p>
<p class="actionButton"><asp:LinkButton ID="SetPriorityLinkButton" runat="server">Prioritize Case</asp:LinkButton> </p>
<p class="actionButton"><asp:LinkButton ID="OpenCaseLinkButton" runat="server">Open Case</asp:LinkButton> </p>
<p class="actionButton"><asp:LinkButton ID="RegisterExhibitLinkButton" runat="server">Register Exhibit</asp:LinkButton> </p>
</div>
I WANT TO TO DO SOMETHING SIMILAR LIKE IN THE CASE ADMIN PAGE BUT AM WONDERING WHAT THE CODES WILL ADD UP TO BE LIKE IN THE MASTER PAGE.
THANKS...
I actually just wanted to load a form
that is created in another asp. page
into the main content area...
I fear that what you need is not UpdatePanel but rather "ordinary" AJAX loading that other page contents into some element.. using jQuery it's as simple as:
$("#OtherPagePanel").load("OtherPage.aspx");
Where OtherPagePanel is the ID of some element in your .aspx code.
You can pass parameters to the other page over the URL, if you need to Post data it's still possible but requires some extra lines - let us know in such case.
Edit:
In the placeholder where you want the data from other page to appear, have this:
<div id="OtherPagePanel"></div>
Have such link in the other placeholder: (no need in LinkButton, ordinary HTML link is enough)
<a id="lnkShowOtherPage" href="#">Show other page</a>
Now in the <head> section of your master page add this code and it's all done:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$("#lnkShowOtherPage").click(function() {
$("#OtherPagePanel").load("OtherPage.aspx");
});
});
</script>
You can also copy the jQuery.min.js file to your own server and change the src accordingly.
Edit 2:
In order to debug add such lines to the code, it will tell what went wrong:
<script type="text/javascript">
alert("JS code in general: OK");
$(function() {
alert("Page load: OK");
$("#lnkShowOtherPage").click(function() {
alert("Link click: OK");
$("#OtherPagePanel").load("OtherPage.aspx");
});
});
</script>
Reload the page and let us know what alerts you get.
Edit 3:
Based on the previous debug results, have this code now:
<script type="text/javascript">
$(function() {
$("#lnkShowOtherPage").click(function() {
alert("OtherPagePanel length: " + $("#OtherPagePanel").length);
alert("OtherPagePanel load: " + $("#OtherPagePanel").load);
$("#OtherPagePanel").load("OtherPage.aspx");
});
});
</script>
Edit 4 and hopefully last:
In order to load different page into different div by clicking different button in addition to everything you already have, have such code:
<script type="text/javascript">
$(function() {
$("#lnkShowOtherPage").click(function() {
$("#OtherPagePanel").load("OtherPage.aspx");
});
$("#lnkShowDifferentOtherPage").click(function() {
$("#DifferentOtherPagePanel").load("DifferentOtherPage.aspx");
});
});
</script>
Is it a postback trigger or an async postback trigger?
i think you can register controls as post back or async on a script manager level with:
Control oControl;
ScriptManager1.RegisterAsyncPostBackControl(oControl);
you could try that
