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.
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.
Can a required field validator be called from the code behind page?We have several check boxes and some of them require the user to enter a date, but not all of them.(This is not a checkbox list, but individual checkboxes).Any 1 of 6 different checkboxes selected makes a txtBox visible for users to enter a date.If they don't select one of these checkBoxes which require a date - it doesn't matter, the form will still be valid.I don't think validation groups can work here so looking towards doing through .vbHere's the existing code:
I'm trying to create a custom control that has a dropdown list and a required field validator in it.I've got as a far as being able to set the error message if the control fails to validate, but I can't actually get it to validate, not can I figure out how to call a .Validate method server side. This is driving me nuts! To create my control, I followed the article here I ran the text box example through, and I can get that to validate without any problems, so I then went through and created a new set of class files relating to a drop down list.Anyone got any thoughts, or hints as to what might be wrong, or where I should start looking?
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?
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.
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 am trying to get the required field validator to work. I have given it an initial value of the first index value in the dropdown list. I is just not working. Will my contrrols residing on a View of a Multiview control effect anything. I am using all drop down lists?
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:
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:
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 have usercontrol which has required field validation in it. I have 2 instances of this usercontrol in single web page . Now if I click button on first usercontrol the validation messages are fired for 2 user controls. But only the required fields of that user control has to be fired.
