Web Forms :: To Add A Required Field Validator To A Text Box On Page?

Jan 11, 2010

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.

Web Forms :: Required Field Validator - Called From Code Behind Page?

Nov 25, 2010

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:

Web Forms :: Is Using Both A Required Field Validator And A Compare Validator

Mar 1, 2010

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?

Web Forms :: Required Field Validator Not Catching Empty Field?

Feb 3, 2010

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?

Web Forms :: Required Field Validator Inconsistent?

Mar 9, 2010

[Code]....

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.

Web Forms :: Use Of Asp.net Required Field Validator For Checking Name?

Oct 14, 2010

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 ?

Web Forms :: Gridview Update Not Firing With Required Field Validator?

Feb 17, 2011

I have a gridview that contains a textbox, a drop down, and a checkbox. The commandfield of the gridview has ShowEditButton="true". All of the gridview updating takes place in the "_OnRowUpdating" event. I have a Panel above the gridview with a table and some fields. Everything in the gridview works perfectly, the edit, the update etc., however, when I add a requiredfieldvalidator to the panel above the gridview, the gridview update functionality no longer works. e.g., clicking the update button does not appear to fire. If I comment out the requiredfieldvalidator, everything works fine.
