why the ValidateRequest dose not work when html tags had sent by __doPostBack method in javascript.

How can I remove all html tags and script tags? consider also short tags like unclosed tags
<script>blah...</script>
<body> aaa<b>bbb</body>
This should return aaa bbb.
notice that all the contents inside the script tag is ignored.
Here's the situation. I have an aspx page that is designed to receive a POST request with some XML values, parse the XML, grab the relevant items, and write them to the page. The problem arises when I try to launch the page using the POST request. When I launch using Fiddler, building the request manually and just pasting the XML in the body of the request everything works fine and dandy. When I launch the page from a basic HTML form, however, things don't go so great. The HTML form that I'm using looks like this:

When the page loads I get the error:
A potentially dangerous Request.Form value was detected from the client Everything I've read so far has told me that the solution is to add ValidateRequest="false" to the page directive in the top of the .aspx file, or in the pages element of the web.config file. But neither of these work. Afterwards, I still get the same error. Any idea what I need to do to make this work?

I want to implement readmore/less feature. i.e I will be having html content and I am going to show first few characters from that content and there will be a read more link in front of it. I am currently using this code :
var txtToHide= input.substring(length);
var textToShow= input.substring(0, length);
var html = textToShow+ '<span class="readmore"> … </span>'
+ ('<span class="readmore">' + txtToHide+ '</span>');
html = html + '<a id="read-more" title="More" href="#">More</a>';
Above input is the input string and length is the length of string to be displayed initially. There is an issue with this code, suppose if I want to strip 20 characters from this string:
"Hello <a href='#'>test</a> output", the html tags are coming between and it will mess up the page if strip it partially. What I want here is that if html tags are falling between the range it should cover the full tag i.e I need the output here to be "Hello <a href='#'>test</a>" . How can I do this?
i'm doing ajax website using PostWebRequest() function, when i call any .aspx page to the target html element the output is coming fine in IE but in FF(FireFox) is coming in html format(html tags) IE output : [URL] FF output : [URL]
javascript functions :
function PostWebRequest(postPage, HTMLTarget, parameter) {
displayElement = $get(HTMLTarget);
displayElement.innerHTML = "<div style='text-align:center;'><br /><br /><br /><br /><br /><img src='images/ajax-loader.gif' algin='center' /></div>";
var wRequest = new Sys.Net.WebRequest();
wRequest.set_url(postPage);
wRequest.set_httpVerb("POST");
var body = parameter;
wRequest.set_body(body);
wRequest.get_headers()["Content-Length"] = body.length;
wRequest.add_completed(onWebRequestCompleted);
wRequest.invoke();
}
function onWebRequestCompleted(executor, eventArgs) {
if (executor.get_responseAvailable()) {
if (document.all) {
displayElement.innerHTML = executor.get_responseData();
}
else {
displayElement.textContent = executor.get_responseData();
}
}
else {
if (executor.get_timeOut()) {
alert("Timed Out");
}
else {
if (executor.get_aborted())
alert("Aborted");
}
}
}
I am raising an event from the javascript function using the below code.
javascript:__doPostBack('<%=lnkSaveBtn.UniqueID %>','');
The event fires when using the below URL
http://localhost:2000/myProjectName/Home.aspx
But when i deploy the project on the production server, it does not raise the event although i have checked that the function getting called but the event is not raised.
In short
* javascript:__doPostBack('<%=lnkSaveBtn.UniqueID %>',''); in javscript works using http://localhost:2000/myProjectName/Home.aspx
*javascript:__doPostBack('<%=lnkSaveBtn.UniqueID %>','');not works when using http://machinename/myProjectName/Home.aspx
I have tried using javascript:__doPostBack('<%=lnkSaveBtn.ClientID%>',''); but still does n't work.
Is it possible to send a html text entered in asp.net text box without making validaterequest to false.
View 1 RepliesI'm trying to manually call the ASP.NET (3.5) javascript postback function __doPostBack from my javascript code. The problem is that the postback script block, that is normally rendered right after the beginning of the <form> tag (and the hidden fields), is occasionally rendered near the closing </form> tag. Is there any way to force it to be rendered near the beginning of the form tag? Also, how does ASP.NET decide when/where to render the postback client script block?
Edit > Additional Info: The javascript code resides inside a user control that references the __doPostBack function. The control itself does not contain any 'postback controls' that would call that function. (When I mention 'postback controls', I mean ASP.net controls that call the __doPostBack function and not the asp.net ImageButton and Button controls)
Based on what I've observed and @Brian's comment on the dependency of the postback script on the availability of 'postback controls' on the page, I've found that when the page contains controls that cause postback, the __doPostBack script block is rendered after the opening <form> tag and when there are none, it renders them near the closing </form> tag (or according to this it's not even supposed to be rendered). Now it would make sense for ASP.NET not to render the postback script if there are no controls that require it, but the apparent position of the script near the closing tag is the one that still eludes me. I haven't been able to find any documentation that suggests this behavior. All I've been able to find was this.
Add a 'postback control' and set its visibility to hidden via css (not the Visible property). eg. <asp:LinkButton ID="RequirePostBackScriptLink" runat="server" style="display:none;" /> (this is what I'm using) Add the control to the Page.RegisterRequiresPostBack and implement the IPostBackDataHandler interface.
Finally, as @Jonathan_Bates mentioned in his post, the proper thing to do is to wrap the reference to __doPostBack inside a function that is an event handler to load (or ready if you're using jquery). That way, there wouldn't be a need to depend on the actual placement of the __doPostBack script.
so I've got some HTML that's generated dynamically. Part of it
StringBuilder.Append("<input type="button" onclick="Email_Clicked" value="Email" class="button" runat="server" />");
I need this to call C# method Email_Clicked
How can I accomplish this without asp:button control?
I have a textbox and i want the user to be able to submit a youtube embed code.
Is this possible without setting 'ValidateRequest' to false?
After upgrading our project to the .net 4.0 framework (from 3.5), we facing some problems with ajax calls with html in the parameters. As soon as the user enters some html in a text area the ajax call isn't executed anymore. If the user enters plain text only, there is no problem.

I have to break a HTML content string in to multiple lines. And each line should have some fixed characters, 50 or 60 Also I don't want to break the word..or html tags...
ex : <p>Email: <a href="mailto:someone@gmail.com">someone@gmail.com</a></p>
<p><em>"Text goes <font color=red>Hello world</font> Text goes here and Text goes here Text goes here 1976."</em> </p>
How can I acheive this in C#?
I've noticed that setting ValidateRequest="true" on the page blocks input of the form • but not • - which are the same characters. Does anyone know why the first type is not allowed but the second type is?I really could not find a place where it defines what is meant by dangerous script and what is actually blocked when the ValidateRequest is set to true.

View 3 RepliesI'd like to get an HTML5 video player working in my mvc 2 project - specifically Kaltura video [URL] , so im trying to integrate their demo html into my Index.aspx..and i get a "Validation (XHTML 1.0 Transitional): Element 'video' not supported"

And im basically just copying their example.html here: Is it becasue of <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" [URL] in my Site.Master? I'm guessing maybe the word "Strict" is not allowing video tag since HTML5 isnt W3C complaint?
I have a long string containing the ,<p> </p> and <br>. I want to clean my string from all these tags and spaces. How it can be done with String.Replace() method. I am doing separately right now, it is working but is there a way to do it at once, without replace() method.
String.Replace(" ","").Replace("<p>","").Replace("<br>","")
It is giving me clean code but I am looking for a general solution, means if I am having more tags (10 to 20) to filter then how to do it efficiently.
how can i use basic html tags(h1,h2 and <p>) in code behind.
View 4 RepliesFor the last time I've been using EWS MAPI to connect to Exchange Server. After this is done I access my mails and firstly display their body (which contains a LOT HTML-tags) in a gridview. After you select a record of that gridview the body is shown in a freetextbox.
View 3 RepliesI have a text area in my ASP.NET web application that is used to enter html code. Now there is also an button control, which upon clicking should retrieve just the text placed between certain html tags in the text box. For example:
1) User types html code including tags etc. and clicks the OK button
2) In my code the text from the text area is retrieved and only the part between a <p></p> tag should be saved to a string object.
I can obviously get the text from the text area and attach it to a string object but I am not able to work out how to just get text within a certain html tag like <p></p>
I want to get some data from html tags in a web page. For example I have a web site that's got [URL], this is text which I want to split. I want to first URL, First text thats between in first span tags and last text that's between the last span tags.
How can I do this with C# ASP.NET 2.0 (not 3.5)?
