I am assuming you mean using XSD files. Surprisingly there aren’t many python XML libraries that support this. lxml does however. Check Validation with lxml. The page also lists how to use lxml to validate with other schema types.
Is that what you had in mind? http://jsfiddle.net/erqrN/1/ <label class=”required”>Name:</label> <input type=”text”> <style> .required:after { content:” *”; color: red; } </style> .required:after { content:” *”; color: red; } <label class=”required”>Name:</label> <input type=”text”> See https://developer.mozilla.org/en-US/docs/Web/CSS/pseudo-elements
You should first correct your validating events this way: private void textBox1_Validating(object sender, CancelEventArgs e) { Regex regex1 = new Regex(@”^[a-zA-Z]+$”); if (!regex1.IsMatch(textBox1.Text)) { //To set validation error errorProvider1.SetError(textBox1, “Nosaukums nedrīskt saturēt ciparus!”); //To say the state of control in invalid e.Cancel = true; } else { //To clear the validation error this.errorProvider1.SetError(this.textBox1, “”); } … Read more
I agree with the other comments that validating a name is probably a bad idea. For virtually everything you can think of to validate, there will be someone with a name that breaks your rule. If you’re happy with the idea that you’re going to be blocking real people from entering their names, then you … Read more
I would suggest an experiment that i have only been trialling for the last week or so. Based on this inspiration i am creating DTOs that validate a little differently to that of the DataAnnotations approach. Sample DTO: public class Contact : DomainBase, IModelObject { public int ID { get; set; } public string Name … Read more

In case you aren’t using ajax, or are still on JSF 1.x, and you really need to invoke a business action in cancel() method (i.e. just reloading the page is insufficient), then your best bet is to add immediate=”true” to the button. This way all input fields which don’t have immediate=”true” will be skipped in … Read more
You can create a custom validation attribute for comparison two properties. It’s a server side validation: public class MyViewModel { [DateLessThan(“End”, ErrorMessage = “Not valid”)] public DateTime Begin { get; set; } public DateTime End { get; set; } } public class DateLessThanAttribute : ValidationAttribute { private readonly string _comparisonProperty; public DateLessThanAttribute(string comparisonProperty) { _comparisonProperty … Read more
<form class=”upload-form”> <input class=”upload-file” data-max-size=”2048″ type=”file” > <input type=submit> </form> <script> $(function(){ var fileInput = $(‘.upload-file’); var maxSize = fileInput.data(‘max-size’); $(‘.upload-form’).submit(function(e){ if(fileInput.get(0).files.length){ var fileSize = fileInput.get(0).files[0].size; // in bytes if(fileSize>maxSize){ alert(‘file size is more then’ + maxSize + ‘ bytes’); return false; }else{ alert(‘file size is correct- ‘+fileSize+’ bytes’); } }else{ alert(‘choose file, please’); return … Read more
