Solution 2

ASP.NET supports this out of the box. We have ASP.NET ValidationSummary Control[^] which can be used here. Check the link. More readings - Google search - validation summary in asp.net[^]

To use asp validation controls, place the validation summary, than validators for the each field which you want to validate, assign a Target Control ID and so on.

while in the posted solution above, you just have to add jquery reference once in the head tag, and than just add an attribute in the existing HTML content and that's it..

So what is more time saving??

Ankur^\m/ 13-Mar-14 6:08am

It is about performance and not time saving. Adding jQuery and plugin script files add to the total download time of the website. Plus the plugin contains many other features which is not required. A simple validation control or javascript method will be way too faster.

VICK 13-Mar-14 6:15am

Well.Agreed to some extent.. @ Ankur :)

VICK 13-Mar-14 5:17am

""""Moreover, just few lines of JavaScript will do that"""

So would you be adding few lines of Java Script along with the 50 lines of validators plus a single line of validation summary for a form which contains 50 fields to validate???

Ankur^\m/ 13-Mar-14 6:09am

No, by that I meant if you do not use validation controls, it still can be done with just a few lines of JavaScript.

VICK 13-Mar-14 6:14am

Can you post a bit of code or a better link, which contains short and concise javascript based validation solution, which should be working for the common validations like asp validation controls?? i.e. required, regular expression etc?

I am not an expert developer, but as per my understanding, for a naive user asp validation controls are a best choice to get started and have an understanding of validation work.

But after being a bit more experience, when along with the task completion, look and feel of the application is concerned as well, than we should have a look at this type of plugin.

Ankur^\m/ 13-Mar-14 6:26am

Required validations:
Lets say if you have few controls that you want to check if they are not empty. I would write
var isValid = true;
if (document.getElementById("controlId").value == ")
isValid = false;
Similary I would write this for all of the controls (as they are few of them). And at the end if the function I would return isvalid.
Now if there are lot of controls, I would probably assign them a common class. I will then select the controls based on class and loop through them to see if their values are blank or not and thus valid similarly.
In the same method I would write other validations.
Also if I already have already called in the page jQuery in the page, the syntax will become much easy. Nevertheless you could do everything in JavaScript. That is how we used to do before.

Ankur^\m/ 13-Mar-14 6:28am

Just to mention, the plugin also works on similar principles (the class one I mentioned in my previous comment)

VICK 13-Mar-14 6:31am

Well, So final verdict is that if we want to get some headache or want to practice javascript,we can write the manual validation code, and if we want a ready made solution, we can get the validationengine type plugins in. :D

Solution 1

If I have understood you properly, you want multiple validation messages showing for a single field. Is it so??

If YES, than answer to your question and resolution to all your problems will be JQUERY Validation Engine Plugin.

You can have a further and deep look at this plugin over HERE

Really? ASP.NET supports this out of the box. Moreover, just few lines of JavaScript will do that. Why would I need a jQuery plugin for this?

VICK 13-Mar-14 5:14am

You can google for the benefits of JQuery over JavaScript. further have you seen this Plugin in detail?? It has a lot of pre defined validation types and its better to use a ready made robust solution rather than searching for the javascript chunks for each validation type.

Further Ankur\m/... If you have any better solution in JavaScript. Kindly Please share it here to help others.

Ankur^\m/ 13-Mar-14 6:13am

Do you know that jQuery is build upon JavaScript? Just checking if a some control is blank or a couple of other validations do NOT require using a library. I reiterate my previous comment - Just Javascript method / validation controls method will be much faster. Moreover validation controls also provides server side validation feature out of the box. Just check - if (Page.IsValid) and you are done. So you save many lines of code and time there.
Hope I could clarify what I meant there.

VICK 13-Mar-14 6:18am

Well. when it comes to the large forms with a lot of validations required??

Further as it has become a common trend of present era,to perform most operations on the client side to avoid server postbacks/calls, than dont you think using the oldy server side is good idea ??

Ankur^\m/ 13-Mar-14 6:30am

Server side validation is still a MUST do thing. I can disable the JavaScript on my page and very easily pass through your validation system. That will be a big loophole in your system.

VICK 13-Mar-14 6:35am

Hmmm. Yes, but that can be handled as well by displaying the error message like Javscript disabled could cause some functions to malfunction etc.

Well, Lets wrap this debate up with a concise review..

What would be your preference for validation and in which circumstance??
Explain your views for all of three, i.e. server side Controls, Javscript, Jquery.
