My Required validation for a field doesn't work because even the user didn't input anything, the watermark text is sent to the server. What's the best way to handle this? I'm using jquery and asp.net mvc.
View 3 RepliesI have some code where I need two separate required field validators for one control, both in separate validation groups which are then validated by two separate buttons.This approach works well when the buttons are clicked but both validators show if I enter a value in the textbox and then remove it.
Is there a way to turn this"lost focus" validation off? I only need it to validate when the buttons are clicked.
EDIT,Unfortunately, if I set EnableClientScript=false then I dont have any client notifications. What I want is for the dynamic error message to show (effectivly in the OnClientClick event of the button) but not the "lost focus" of the textbox.Is there some way I can disable or "unhook" the lostfocus client event?
EDIT,A combination dDejan's answer and womp's answeer here sorted the problem perfectly.
My final code looks like this (for anyone else with a similar situation)...
Javascript...
<script type="text/javascript">
$(document).ready(function() { [code]....
So, now there is no validation until a user clicks either the "Get Email Confirmation Code" button or the "Register" button. If they click the "Get Email Confirmation Code" button all of the controls validate apart from the textbox where the user is to input the email validation code and we only see one validator message.
If they click the "Register" Button then all of the controls validate and we only see one validation message.If either button is pressed, the user goes back, adds and then removes some text then we only see one validator. Before this change you used to see both messages saying the same thing.
When 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 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?
I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

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 am having one dyanmic grid in that amount and date is not null column user should enter some thing in that spceified column.my issue is that if the save button is pressed the requried validator is firing for all the rows which is empty.it should only show if the user shows in the current row.if the user left the particular row is empty and presses the save button the error message should show in the current row not all the rows. how to do this.

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 ?

Interested in a way to call an event when the Required Field Validator component determines the assigned text field is not valid/empty. Is this possible? Somewhat surprised it doesn't have an event for this. Am I missing something?

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 want to disable the requiredfield validator control for the textbox based on some condition of a variable
if(var==null)
{
//Activate it
