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?

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.

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?

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?

I can't figure out why I might be getting this error. It happens on an ajax call.This is the full error text:

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 created a MultiHandleSliderExtender on a web form. All works well with updating the two textboxes with the value. The problem is that when I switch to designer mode, I get the following error:
The code is as follows:
[Code]....
[Code]....
[Code]....
The control works and the 2 text boxes get updated, but I tried putting in an update panel with a trigger on mh_1_BoundControl but it never fired. I removed it thinking that was the cause of the error, but no luck.
Now when I add another sliderextender below it for a different value, the code throws an error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Type AjaxControlToolkit.SliderOrientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.
I found this example on this site and tried implementing it but to no avail.

I have a grid which houses a modal popup panel. When the grid binds it gives a flicker. The modal popup panel becomes visible for a second and then hides in the grid. Is there a way I can avoid this from happening.

I have a dashboard made of multiple webparts. One of the webpart is a usercontrol with a timer wrapped in UpdatePanel. When it is loaded in the dashboard I notice that it causes a Page_Load, and that triggers personalization procedures aspnet_PersonalizationAllUsers_GetPageSettings and aspnet_PersonalizationPerUser_GetPageSettings to fire.
Can can I avoid that? I read many posts on Timer controls within UpdatePanels, and it is my understanding that Timer would cause a full page postback, but only render the UpdatePanel that it is part of. However, these personalization functions execute every time Timer ticks.

am trying to fix an issue. I have an ASP.NET Ajax's TabContainer on the page. And each tab there is a gridview control that gets binded onload. However for some reason the browser gets closed automatically after the page renders. If I remove the TabContainer then it works fine. I think the binding code will no way effect the browser to close bacause no where in my code I am registering any Script block.Also one notable thing is this happens only in IE 8. It works fine in firefox and other browsers.I don't know if anyone encountered a similar issue before.

I have the following tabpanel (it actually contains a bit more content, but that content doesnt influence my issue):

When I remote the MaskedEditExtender and MaskedEditValidator, it doesnt show that (undesired) behaviour anymore.Is there something special these controls do that cause them to refresh? Is there a workaround for this?

I think ive narrowed down my problem, I have a form but the "submit" buttons are being handled by Javascript - since i need to build arrays manually outside of the model for processing
[Code]....
I'm calling the Controller Action "Update" and passing it to string Arrays, when its finished - i want it to redirect to another action - it doesnt.
[Code]....
I just really wanna construct those arrays, and pass them to a controller...i think the ajax is waiting on a result and ignoring the redirect.

Below is the sample code on using the update panel. The page just has a button and a label. On button click it updates the label with the server time. Though the label is inside the update panel the page goes for a complete postback. in understanding why it is behaving like that. I tried the options of Updatemode, using different script references nothing seems working for this simple application.

I am using VS 2010 and making extensive use of tab panels with gridviews inside of each. I very often am required to reformat the whole document as it seems that the gridview mark-up gets completely reformatted in one continuous line. In the act of reformatting unwanted things get inserted such as linebreaks. When I was using VS 2008 this behavior was even worse. Does anyone have a suggestion to fixing this issue? I am wasting time because things are changing visually and tested work is getting automatically changed.

I have a gridview which has a checkbox column which are set to automatically postback. When a checkbox is clicked, a partial postback occurs, and the associated record is displayed to the user (this is the required function).My problem is regarding when a user clicks a number of checkboxes in quick succession. I have got ajax request queuing working fine, so each checkbox postback is eventually dealt with. However as the gridview also postsback, it resets its viewstate on which boxes are checked, removing some of the boxes which the user may have checked.I've attempted to take off the viewstate on the gridview which seems to achieve nothing, neither does placing the gridview in a separate update panel.

If a user enters "<" or if it already exists in a textbox inside an update panel, I am getting "internal server error 500" during post back. I believe the page suspects a HTML injection and is attempting to stop it. I could use Page.EnableEventValidation to avoid it but I really don't want to do that. Is there any other way, I could resolve it (like replace < with > or something like that)?
Update:
This is happening in a textbox inside a gridView.

I have a modalpopupextender and I want to be able to update the information without causing a postback and having to re-show the modal, normally I use an updatepanel and this is working in most cases but I have an issue with a repeater where the ItemCommand has been set but clicking the button does not fire anything, unless I set the repeater as a trigger but this then does postback and I lose where I am. Not the usability I want to provide.

I have a link button inside a template field of a gridview. The gridview is wrapped in an update panel. I want the link button to fire an async postback but it always fires a full postback. Why is this?
This is a similar problem to the one described in the link below. However, I have tried doing a RegisterAsyncPostbackControl in the gridview databound, but this did not work.

Since last week I've had a really odd issue with PageMethods and the back button which i've never seen before. Essentially, I have a 'home page' which on document.ready (using Query), loads some data through PageMethods, and then renders a list - from which you can click through to a details page about the item. In general use, it works fine. However, using the back button after clicking through (ie: going back to the home page), it throws a PageMethods error. The browser's 'authentication required' prompt appears, and if you click cancel, the server returns a 404. The error returned by PageMethods on the client side is 'authentication failed'.
Just FYI, the application is using ASP.NET forms authentication. The weird thing is, this happens as soon as you click the link and click back. It's not like the authentication cookie has expired or anything, and if you click cancel when the prompt appears and refresh the page, it works fine. I just can't work out what is going on. I've tried disabling caching on the page [as I thought it was something to down with some browsers' caches of the DOM), but the same thing happens. One workaround i've had is to redirect the page to itself if the PageMethods error is 'authentication failed', which does work - but only when you cancel the authentication prompt. Obviously the prompt appears, which is not ideal. I don't understand it, and the user is clearly authenticated. Does anyone have any idea which might be happening? It's happening in Chrome, Firefox, and IE.

I am having issue with my ModalPopUpExtender's OKControlID. I have a button inside an update panel that should do AsyncPostBack. The button works fine and runs server side code but it causes full page postback. How do I solve this issue? I want the 'OK' button inside the modalpopup to call the serverside code and update Label control 'label3' without causing the page flash. Given below is my code;
MarkUp:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>Next Gen Web Browser</title>
<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.js" type="text/javascript"></script>

This is likely a n00b question, but I can't seem to find any info on how to solve it. Here's the scenario:
I have a Textbox and a RadioButtonList in an UpdatePanel, both with AutoPostBack turned on (they need to be, can't turn it off on the text box))
The user enters some text in to the textbox, then clicks one of the Items in the radio button list.
Because the textbox post back is executing, the radio button is losing the value that the user selected.
How can I workaround this?

So am adding fields in the code behind and now want to add required field validators. Kicker, I think comes into play becasue all this is in a master page. So even though I may set the id of the textbox to say tb4, it's no longer tb4. So when I add the required field validator and tell it the control to validate is tb4, I get the yellow screen of death telling me thtat tb4 does not exist... cause it's the long huge master page ID. What do I do?
