I have a details view with editing enabled. When editing, if the value of the CurrentResident field is changed from Y to N (it is restricted to Y/N), I want to activate a required field validator on the DepartureDate field. The DepartureDate attribute allows nulls in the database structure, but I want it to be required if the client is no longer a resident. How can I accomplish this?
View 1 RepliesI have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
Is it possible to have "Required Field Validator" controls to validate more than one field (example I have 12 textboxes that are required. I want to try an avoid having 12 RFV controls. If a validation does get triggered, is there a way to display a customized message ("textA is empty" or "textB is empty") etc.?
View 4 RepliesWhen it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?

I wish to perform validation on the page only when the "add exhibit button" is clicked. so in my code behind, i used an "if(page.isvalid)" to check for page validation when the button is clicked. However any other button i click fires the validation as well... I presume its because every button click tries to load a page and that calls the validator to action. how do i allow work around the validation such that, only the " add exhibit button" triggers the page validation?
Page validation using Required field validator is not firing I configured everything and tested in other page and found its working fine.
I placed my controls under TabContainer is that the reason for not firing.
I have the need to remove my custom field validators on the clientside based on certain conditions

I want to put validation on a combobox to ensure user selects/enters a value. I've tried using a the standard required field validator which doesn't work. So I would like to do the validation using javascript/jquery.
Not sure how to approach. When I look at how the combo box is rendered, it appears as a unordered html list. There is also a hidden field but this always seems to be set to 0.So is it possible to do this validation client side. I've read so many posts about this but I havn't got an answer yet.

I have a form that contains times and dates. Each of these controls has a required field validator so that the user must put in the date and time. This apprears to work fine in testing. The data is stored in sql tables which are then worked with in the office using an Access Database. The webforms are simply used for gathering the data. In analyzing the data, they are finding that there are instances when no time has been stored. I don't know how the insert information could be saved if the control was blank. To make matters worse, the staff swear that they are entering the times.
I'm trying to use the regular expression validator for a numeric ID field.The field needs to be a required field of any number.Currently, I'm using:
="d{1,}"
Shouldn't this make it so the user has to at least enter 1 digit?? If I hit the submit button with the field empty,it passes validation and posts back.But if I enter non-numeric characters, it errors fine. If I wanted zero or more occurrences,I'd use:
="(d{1,})?"
Why isn't this working? Do I need to use this in combination with a Required Field Validator? That would suck ><
Sometimes while registering on the website people don't provide correct details like name and e-mailIn order to check correct e-mail it is better to use e-mail activation link send to their e-mail.But how to make sure the user is providing correct name ?I am really impressed by the Facebook name recognition system, it we try to use any word which is not a name, it asks you to enter a valid name.Is there any way we can make use of asp.net requiredfieldvalidator to check if user is providing a correct name or not ?I know we can make use of requiredfieldvalidator to see how many alphabets / special symbols etc butIf we put minimum alphabet requirement - in that case user can enter "....." and can easily bypass the requiredfieldvalidator or a user can easily write "iamfakeuser" instead of name and bypass the requiredfieldvalidator.
question is how to check if name is correct or not just like facebook registration form ?

I need to add a Required Field Validator to a text box on my page. When I add the validator the following happens when I run the page:
When I click the submit button the page doesn't submit because the page is invalid. No error message displays despite my having set the ErronMessage. When I click inside the text box that has the Validation, then the Required error message shows. When that textbox loses focus the error message goes away. The only way I can get the page to function correctly is if I create 2 Validators for the same text box. The first validator is set to have an ErrorMessage of "" and the second one is a regular error message.
I have used these before many upon many times and never experienced this. Below you will find the Source code.
[Code]....
This code is the only way I am able to get the validation to function correctly where the ErrorMessage displays when I leave the field blank. I appreciate any help on resolving this issue. I have deleted/re-added the validation control many times. This is the only page this type of error happens on.
