Client side Validations are not working

Hi all, 
I have a Registration Page which is used for registering new users. on the Client click of a button "Submit" i have written a javascript code "return Checknull()". CheckNull is a function in javascript externally written in file called MandatoryFields.js. When I run the application. I am getting an exception in the code behind where i have written the code for saving the fields, whenever i just click on the button without entering the details for registering. what could be the Problem. I have given the script tag also...

Please help me.

I think that ur have disabled the scripting in ur browser.If u r using IE the go to properties of IE and there u will have ADVANCE Tab.Just Click on that remove the "check" from "Disable Script Debugging".I think then it might work

 I think it's better to use ASP.NET on validator control. They serve the same purpose.

Did u use return false in your javascript code whenever the field is null ?

Did u check whether the javascript function is getting called by giving an alert message on start of the method?

Client-side validation works, but server-side does not.
Hey all,I have got this text box control on my webform, which has two validators.. 1. RegularExpressionValidator and 2. CustomValidator.Now, RegularExpressionValidator control works if I enable client-script. But somehow it does not work for server-side validation. Any idea why this is happening? This happens to another textbox control on other web form as well which has similar coding.

Validation Controls in .NET ( Client side or server side?)
 i have a very basic question. We have all these validation controls in ( required field, range validator and others) question is the required field validator is a server side control.

Server side validation affecting client side validation
Hi there I have some client side validation that is working fine and enables/disables buttons based on user selections. This works great. However, when I perform server side validation using custom validators (like checking if the user has entered < HTML > tags or decimals in the integer boxes) and the server side validation returns isValid = false then all of the JavaScript validation that I've already done when the user clicked each control is lost. I don't understand why the enabled/disabled state of the control is not maintained.  What is calling the JavaScr...

avoiding redundant server-side validation after client-side validation
I see an inaccurate validation behavior on my (2.0) form. The EnableClientScript property of my validation control is set to True by default, so it performs the validation on clientside. But as soon as this occurs, it also performs the server-side validation, so the page refreshes. When the validation error occurs on clientside, it should not do the validation on serverside (I'm not calling Page.Validate() or doing Page.IsValid). In my past experience, handled this automatically, but I guess it's not always the ca...

Client side or server side validation???
I have multiple usercontrols each displayed by pressing a button and then change the apperance to a new user control and so on. I have to check that almost every field in this user controls have a value entered, and then indicate (e.g. with a red star) those textboxes that does'nt have a value entered. How should I do this in the best way, client side or server side with some validator? I have in mind that when using a server side validator, it may dissapear when making a postback. But I'm not sure, and I assume there is a way to come around this problem?What do you all say? Client side or s...

validation, is it better to have client side or use server side validator controls
 Hi All. I want to do validation on text boxes etc. Is it better to do client side validation or just use the server side validation controls?   Hi!  If for server side controls you mean RequiredFieldValidator, CompareValidator, RegularExpressionValidator, etc.. i can tell you that they use client and server validation. For instance if you use a RequiredFieldValidator, on the client will be a validation, but on the server this condition will be evaluated again. Probably one of the objetives of this is deal with client with javascript disabled. Of course I ...

Disabling Client Side and Server Side Validation
I have a page which contains a User ID and Password field which have RequiredFieldValidators against them. The page can also load a User Control which contains another field which also has a RequiredFieldValidator against it. When I submit the form I use the ValidatorEnable function to disable the validator, on the User Control Page, when the user is signing in. This works fine on the client side but the page fails on the server side as I presume it does not know that I have disabled the control from the client side. Can anyone tell me the best way to solve this problem. Thanks M...

When do the validators kick in? Are they server side or client side?
 Hello,I am confused. I was under the impression that validators work on the client side.But I was confused when I set the enabled property of validator to false and then the validator did not work. (RegularExpressionValidator1.Enabled = false;)But the other confusing thing to me is that if the validators  work on the server side then when don't i see the page refresh like on other postback events? Kindly throw some light.Thanks!   Validators always work on the server side (assuming they're enabled), but also work on the client side if EnableClientScript is t...

I wonder if this is the right forum to post this question because it is an issue about both server and client side processing. I am developing a web application (online store) which will run in a hosting company. Users accessing this app will be able to place orders with one limitation; the store has a schedule to accept orders. For example, it can be open from 8AM to 10PM and/or it can be closed on Mondays. I just can't validate time and/or day directly because time zone may lead to wrong results. So I thought about getting the schedule information, which is saved in my database, ...
