Even many spaces are validated okay. I don't need this to be mandatory. I can trim on server, but cannot regular expression do everyt...

Hi all, Pretty simple question. I have a few ASP RequiredFieldValdators checking some text boxes. Out of the box, it checks validation when a button is pressed, basically disabling it unless all fields are met. I also have a listbox with a bunch of data points, which load new data into the text boxes that are being validated. I want...
I have a group of checkboxes that all have the same name. They all have different values. They are just part of a form. They do not make up the entire form. I want the checkboxes to display their error AFTER the last checkbox of that group. is it possible to do something like this in jQuery? $("#myform").validate({ errorPlacement: fu...
Hi all, My form validation works great, but the messages use the JSF component name and not the field label. For instance, I have a field subject and the error message I get when it is empty is something along the lines of: UIComponent:contactBean.firstName cannot be empty. My Form: <div class="field"> <s:decorate id="firstNameDecor...

I'm playing with LINQ-To-SQL in .NET 3.5 and have built some classes based on an underlying database. I now face the decision: do I validate data in the class code, or in the database? I can see pros and cons either way. If I do validation in the database, the validation takes place no matter what app is using the database. (I currently...
How can I validate an XML file against a DTD that is stored locally as a file? The XML file does not have any DOCTYPE declaration (or may have one that should then be overridden). I had a look at this thread but besides the fact they are using .NET I doubt that this is a good solution. Any input appreciated! ...
I needed a function that simply checks if a string can be converted to a valid integer (for form validation). After searching around, I ended up using a function I had from 2002 which works using C#1 (below). However, it just seems to me that although the code below works, it is a misuse of try/catch to use it not to catch an error but...

I have a simple contact form with Subject and Message that I want to validate to prevent blank e-mails. ActionMailer doesn't support validation.

One of the first things I like to do when I make a site is to put in links at the bottom of the page to check for valid HTML and CSS: HTML5 • CSS <div> <a href="http://validator.w3.org/check?uri=referer">HTML5</a> <a href="http://jigsaw.w3.org/css-validator/check/referer/">CSS</a> </div> However, when you...
Hi all, I use django and I wonder in what cases where model validation should go. There are at least two variants: Validate in the model's save method and to raise IntegrityError or another exception if business rules were violated Validate data using forms and built-in clean_* facilities From one point of view, answer is obvious: o...
I wrote a UserControl that attaches a Javascript function to a form's submit button. The Javascript function ensures that the page is valid by calling Page_IsValid and then proceeds to execute some code. For the problematic pages, the Page_IsValid is set to true on first load. If I don't set the OnClientClick, Page_IsValid is correctly...
