Web Forms :: RequiredFieldValidators Are Allowing Postback To Occur?

Jul 28, 2010

I'm adding multiple TextBox and DropDownList controls programmatically on Page_Load. Some of them have attached RequiredFieldValidators that are being built programmatically as well. The issue I'm having is that when the Submit button (also added programmatically) is clicked, a postback occurs before the RequiredFieldValidators mark their respective fields as blank. How can I get these to fire client-side like they're supposed to?

Web Forms :: Create Via C# In An Event Causing Page Validation To Occur On Postback?

Feb 14, 2011

I'm having trouble with an image button I create via c# in an event causing page validation to occur on postback. The CausesValidation attribute is set to false at time of creation in the event. I also wire up the Click event in the page_init with postback so not to loose the event handler if the page posts another way. Here is the code I'm using in the click event of a Button. I've also tried to enable and disable viewstate for the button with no luck. What am I missing here that continues to fire page validation in the Click of this imagebutton?

Web Forms :: Why Does Init Occur From The Bottom Up

Mar 3, 2010

I'm referencing this article:[URL]Specifically, this line:

"The Init event for each child control occur before the corresponding event is raised for its container"

I've never noticed this behavior before, but can definitely see that this is correct. I don't understand WHY this is necessary though. Can someone shed some light on this?

Web Forms :: Scroll Page To The Position Where Validation Errors Occur?

Jul 29, 2010

I have serveral long ASP.Net pages, I use RequiredFieldValidator, RegularExpressionValidator and ValidatorCalloutExtender for validations, Submit buttons are typically at the bottom of the pages. The problem I have: if the errors happen at the top portion of the page when Submit buttons are clicked, the forms do not scroll to the top automatically, the users have to scroll up to see the ValidatorCalloutExtender.

CustomValidators Fire At Same Time As RequiredFieldValidators

Nov 19, 2010

I have a form containing both CustomValidators and RequiredFieldValidators. The Custom Validation doesn't fire until all of the requiredFieldValidators have passed. Can someone tell me how to get them to validate at the same time? I want all the validation messages to show when no data is input.

C# - Server-side RequiredFieldValidators Not Working?

Mar 7, 2011

I have a form representing a survey that is dynamically generated based on some database configuration. I have a custom server control for rendering the survey (SurveyRenderer) which contains custom server controls for rendering questions (QuestionRenderers). I dynamically add RequiredFieldValidators for questions if they are flagged as being required. I add these validators to the SurveyRenderer's control collection.

The gist of the code...

// In SurveyRenderer.CreateChildControls()...
foreach (QuestionRenderer questionRenderer in questionRenderers)
{
if (questionRenderer.Question.IsRequired) [code]...

The client-side validation works fine -- if someone has omitted a required question, the validators catch it and the form doesn't validate. However if I turn off JavaScript and submit an invalid form, the validators do not seem to work.On the server-side I am calling Page.Validate() and checking Page.IsValid in the submit button click event handler. Despite submitting a form where required questions have been left blank - something that would be caught client-side - on the server-side Page.IsValid remains True.

// In SurveyPage.aspx...
public void btnSubmit_Click(object sender, EventArgs e)
{
Page.Validate();[code]....

Should I be adding the validators to the Page's Control collection, rather than the SurveyRenderer? How come it works on the client-side but not server-side?

UPDATE: My QuestionRenderer is annotated with:

[ValidationProperty("IsValid")]

And the IsValid get method is like so:

// QuestionRenderer.IsValid
public bool IsValid
{
get [code]...
If I set a breakpoint and step through, I can see that QuestionRenderer.IsValid is being fired OK. It is returning false when it should do. If I go fine-grained and call in btn_submitClick:

// In SurveyPage.aspx...
public void btnSubmit_Click(object sender, EventArgs e)
{
foreach (IValidator validator in Page.Validators)[code]....

So validator.IsValid is true, even though the call to QuestionRenderer.IsValid returns false. So maybe I haven't wired something up correctly? Is using [ValidationProperty("IsValid")] not enough?

AJAX :: NumericUpDownExtenders Causing RequiredFieldValidators To Validate?

Mar 8, 2010

I have a page that has a few NumericUpDownExtenders, and the same page has some validation like RequiredFieldValidators. The problem is that when you click either of the arrows for any of the NumericUpDownExtenders, it's causing the page to try to validate. This ia making all the "required" boxes for every required field on the page pop up as if you just tried to submit an empty form.If you don't touch the NumericUpDownExtenders, then the page works exactly as intended. The "required" boxes only pop up if you've gone into one of the required fields, typed something, deleted it, and put the focus in another field.How do I fix the NumericUpDownExtenders to make them stop causing the validation?

Multiple RequiredFieldValidators On Page But They Need To Apply To Different Button Clicks?

Oct 13, 2010

I'm working on a asp.net page and I have the following scenario:I have 2 fields that have requiredfieldvalidators which need to "fire" their validation when button1 is clicked but NOT when button2 is clicked and another field which is validated by another requiredfieldvalidator with the opposite scenario. (requiredfieldvalidator for this field needs to "fire" when button2 is clicked but NOT when button1 is clicked.)

I have the following within an updatepanel. If i make a selection somewhere else that has its own updatepanel, this data gets cleared.

[Code]....

What am i doing wrong? each updatepanel has its own trigger assigned to it.. so why would updatepanel#1 trigger cause updatepanel #7 to post and cause the field to clear? Even if i tab out of the textbox before completing it, causes the field to clear..

SQL Server ::error Occur Paste The Generated Query Into Sql Management Studio?

Aug 4, 2010

I have been using a function that replaces some characters from my editor in asp.net with '+CHAR(x)+' to chain together a string with characters such as single quote that would otherwise break the query, i know how to escape the character using double single quote but i was wondering why i get this problem.The problem is that when the string gets too long about 7kb to 8kb its gets cut off for no reason, no error message gets displayed, the query is successful only the string cuts off at a point. When i escape the character without using '+CHAR(x)+' to add the character i can add a very long string that does not cut off,i am using Varchar(max) for my field, (have also tried text).I am using sql 2008 express edition, and encounter this problem when i paste the generated query into sql management studio, and when i execute the query fromasp.net code.

Security :: Allowing Login To A Forms Authenticated Site From Another Location?

Jun 14, 2010

I have a site almost finished that uses ASP.Net membership, forms authentication and roles. There are one or two requirements remaining and I'm not even sure how to properly approach one of them.

The site I've created is going to provide service ONLY through SSL, if that matters. Yes, I'll redirect a request that lands on port 80 but the intent is to encrypt everything.

Is there a "best practice" for creating a session with my site, from another site? In other words the company is building a marketing page that has spaces for a login and password. I can find lots of posts about passing a username and password to another
site to start a session, but very few if any about receiving the username and password.

If anyone can point me to an article or posting with a code sample where the login control of a forms-authenticated site is used as the target of a form hosted as part of a different web page/application on a different host, it'd be awesome.

To be clear, the scenario is essentially "brochureware website on a 3rd-party host" providing the visitor the ability to log in to a secure site on a more "internal" server.

Web Forms :: Validation - Restrict Past Dates While Allowing Edits?

Aug 20, 2010

I have a form that collects some dates. The users can go to this form any time, view the data, and edit the data.

The user should only be able to enter today or future dates only. We don't want users to go in here and be able to past date these dates.

So I created a compare validator which compares the text box against today's date. This works great. The user saves the form and life goes on.

But then, lets say they come back 1 week later and want to change a date. Now all the old dates will fire this validator and they can't save anything unless they change all the dates to today or newer. This is a problem.

So what I thought was when I load the form with the data from the database, I would just disable the validator if there is a date, and if it's null enable the validator. But this won't work because then they can back-date all of those dates with the validator disabled.

So for the dates that are not null, it shouldn't fire the validator unless they change the date.

When I load the form, I'm going to load all these dates into Viewstate. I'm going to create a custom validator and check the value they enter against the previous date that is in Viewstate. If it matches that date then it is valid, if it doesn't match that date then I will run it through the validator to check for past-date.

Web Forms :: Process Radio Buttons As 'group' Allowing For Multiple Selections?

Feb 25, 2011

the form has 15 items to choose with radio buttons, any number can be selected. I would like to process them as a 'group' so I can do something like loop thru them, checking if each one has been selected to build a list and also be saving them to a table row, etc but it seems all the designations as a list or group make it mutually exclusive. just looking for better coding than checking them with an if statement or similar so the question is if there is some way to designate the radio buttons as a group but no force the group to be mutually exclusive

Forms Data Controls :: Formview LinqData Source Not Allowing Updates?

Aug 18, 2010

I've set up a formview with a Linqdata source to allow users to edit records. When I run it, edit data and submit, it blows up and tells me "Linq datasource6 does not support the Select property when the Delete, Insert or Update operations are enabled." I googled that warning and saw a couple of posts on this forum saying the problem is the slect statement has to be removed from the Linq data source for it to allow updates.

But if I remove the select statement then how do I show the user specific info on pageload? plus I thought the two way databind was an advantge of the datasource control.
