Web Forms :: RequiredFieldValidator Works Clientside With Javascript... But Doesn't Validate Serverside With J?
Mar 12, 2010I'm making a website in ASP.NET 4.0 where I make use of the RequiredFieldValidator control to validate a wizardstep.It works perfectly with Javascript enabled, but when I turn it off (in my Firefox) it just goes to the next step.We don't do a Page.IsValid check, but we don't do much on the "next button clicked" event either.Certainly not something that is forcing it to go to the next step.
View 15 RepliesJavascript - RequiredFieldValidator Custom EvaluationFunction Property?
Nov 28, 2010My custom ASP.Net RequiredFieldValidator renders markup like this...
var af1_ctl00 = document.all ? document.all["af1_ctl00"] : document.getElementById("af1_ctl00");
af1_ctl00.controltovalidate = "af1_af1_txt";
af1_ctl00.display = "None";
af1_ctl00.evaluationfunction = "RequiredFieldValidatorEvaluateIsValid";
af1_ctl00.initialvalue = "";
However, there appears to be no way to set the evaluationfunction property. I need to do this to call some custom script.Ive tried the following methods.Adding a new attribute when the control is rendered and when the attributes are rendered Calling RemoveAttribute followed by Attributes.Add Attempting to reset it via javascript.Nothing seems to work.If I can get a solution that works in the c# code to set the attribute before render that would be the best for what Im doing.
Call A JavaScript Method After The RequiredFieldValidator Fires?
Mar 1, 2011Is it possible to fire a JavaScript method after a form element is considered invalid? Here is my scenario:
There are 2 tabs on the ASPX page. The user has to fill out info on both tabs. The user, while on tab 2 clicks the submit button. However, there is a required field on tab one that needs attention. Do I need to create a custom valuator (either a CustomValidator control or create a new control from the base valuator) to call a JavaScript function to display tab 1 and show where the error is?
Web Forms :: Try / Catch Block Won't Write Javascript?
Jun 10, 2010Since everyone yells at me that MessageBox doesn't work when the project is uploaded to the server, I need to migrate to javascript alert box. As I was changing my MessageBoxes, I tested and found that they weren't being produced. I'm not sure if it matters, but they are in a try/catch block, which is shown here:[Code]....
This all worked before when I had MessageBox - it showed, then the page redirected when I clicked Ok.
I either don't understand how try/catch works, the javascript isn't adding, or Response.Redirect is executed before I can see the alert box and click Ok on it.
(just as a note, everything works fine, but the alert box doesn't show)........if I add the (javascript) code before the try block, the alert box comes up, so it's not something wrong with the writing of the javascript or executing it at least (I think).

How To Write JavaScript For Templated Markup
Dec 22, 2010I've been assigned changes to make to an ASP.NET project. The WebForm I'm working on needs to dynamically display and hide controls in response to user actions.
So far, so good. My approach would be to create a little JavaScript. However, on this page, the markup is part of a template for a Telerik control (which I know nothing about). I'm not sure the ramifications of this. Can I still use JavaScript for templated markup?
I tried to insert some existing JavaScript in the page. The first problem I have is my use of <%= ControlName.ClientID %>, which produces an error because the name of the control in the template is not seen to exist by ASP.NET.
Is there another way to do this, or am I just going to run into more problems?

Write / Create Cookies In JavaScript
May 25, 2010I know how to write/create cookies in JavaScript.
//Create the cookies
document.cookie = "Name=" + Name + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Surname=" + Surname + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Number=" + Number + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Email=" + Email + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Country=" + Country + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Company=" + Company + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Title=" + Job + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
But how can I read each one of them in JavaScript because I want to populate the text boxes next time the user come to the form? I have tried this but it does not work:
var cookieName = ReadCookie("Name");
document.getElementById('txtName').value = cookieName;
Edit with Answer:
I used this code.
<script type="text/javascript">
function getCookie(c_name)
{
if (document.cookie.length>0)
{
c_start=document.cookie.indexOf(c_name + "=");
if (c_start!=-1)
{
c_start=c_start + c_name.length+1;
c_end=document.cookie.indexOf(";",c_start);
if (c_end==-1) c_end=document.cookie.length;
return unescape(document.cookie.substring(c_start,c_end));
}
}
return "";
}
function checkCookie()
{
Name = getCookie('Name');
Surname = getCookie('Surname');
Email = getCookie('Email');
Company = getCookie('Company');
Title = getCookie('Title');
if (Email!=null && Email!="")
{
//Populate the text boxes.
document.FormName.txtName.value = Name;
document.FormName.txtSurname.value = Surname;
document.FormName.txtEmail.value = Email;
document.FormName.txtCompany.value = Company;
document.FormName.txtjob.value = Title;
}
}
</script>
And called the checkCookie() function like so from the window.onload
<SCRIPT TYPE='text/javascript' LANGUAGE='JavaScript'><!-- //
window.onload = initPage;
function initPage()
{
checkCookie();
}
//-->
How To Write / Code Javascript (mouseover Event) Using C# Methods

C# - HttpModule To Write Out JavaScript Script References To The Response
Mar 11, 2010On my page in the Page_Load event I add a collection of strings to the Context object. I have an HttpModule that will fire EndRequest and retrieve the collection of strings. What I then do is write out a script reference tag (based on the collection of strings) to the response. The problem is that the page reads the script reference but doesn't retrieve the contents of the file (I imagine because this is occurring in the EndRequest event). I can't fire the BeginRequest event because I won't have access to the Context Items collection.
I tried to also registering an HttpHandler which Processes the request of the script reference but I can't access the collection of strings in the Context.Items from there.

Javascript - How To Write An NPAPI Plugin With Functionality Of WScript.Shell
Sep 2, 2010I am very new to Web development, and have been writing some javascript that makes use of WScript.Shell via ActiveX. I am aware that browsers other than IE don't support ActiveX though.
After doing some digging through Google, I have discovered that I may be able to do something similar on all web kit based browsers via NPAPI. I have no idea where to even begin when it comes to this though. Is it possible to do what I am after via NPAPI? If so, where would I begin?

View 1 RepliesAJAX :: JavaScript Generated Output Using Document.write Does Not Appear In UpatePanel?
Oct 5, 2010I have a ListView (in an UpdatePanel) connected to a LinqDataSource. When the page loads and/or I navigate through Postback, the code snippet (below) will display the following output:
[email.gif] someone@adomain.com [email.gif] www.adomain.com
However, when I use a few DropDownLists (also in the UpdatePanel) to filter the results (reset the DataSource to a Linq query and call DataBind), the same Contact is displayed like this:
[email.gif] [email.gif] www.adomain.com
[Code]....
If the parameter is a URL, the FormatEContact method will return:
[Code]....
So, after spending some quality time with Bing and Google, I've learned that the above js code is treated as just text and not evaluated. Therefore, the most often recommended solution is to eval() it. Unfortunately, I can't figure out exactly how, when or where to call eval().
