Web Forms :: Validation Fails When Fields Are Populated On Page_load
Feb 17, 2011
I'm writing a small web application in c# and i'm running into a small problem.
Basically, on page_load() my backend MySQL db is queried to bring back the user data, and that is then inserted into the textbox controls as below:
[Code]....
Now the problem occurs when the RequiredFieldValidator kicks in. In my form processing function, I call Page.IsValid(), it fails and displays the required message next to the required fields.
I was wondering if there is a workaround for this, or a better way to go about what i'm trying to do.

I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?

Let's say that I have the following HTML for a text box on an ASP.NET page:
<div class="myClass">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>
It is easy enough to add a required field validator to this page like this.
<asp:RequiredFieldValidator ID="valMyTextBox" runat="server" ControlToValidate="txtMyTextBox" ErrorMessage="My Text Box is required."></asp:RequiredFieldValidator>
But I need to modify the HTML slightly if this text box fails validation. I need to add a CSS class to the DIV. So if the user leaves this field blank I need the HTML to look like this:
<div class="myClass error">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>
Is this possible? I can't figure out if there is a way to write code behind that only fires if this particular validator control fails validation or something. I know I can write code that runs when the entire page is not valid. But I just want this code to run when this validator returns invalid. Hope this makes sense.

I am starting a new project in Asp.net MVC 2.I have been mostly a webforms developer and have limited exposure to Asp.Net MVC and hence this is probably a noob question.
My situation is as follows:
I have a create page for saving some data to the DB. The view for this page is not strongly bound / typed - so the way I am extracting the data from the view is by looking at the POST parameters.
Incase there is an error (data validation, etc), I need to send the user back to the previous page with everything filled in the way it was and displaying the message.

At first, I had my datalist being populated by my class 'PM' - I did it all inside the Page_Load event. Since there was a dataset being returned, I could assign different variables to fields in the Datatable, like:
[Code]....
Now, for reasons I won't go into here, I'm changing to an ObjectDataSource, using the same method to do the 'Select' of data... How can I do the same variable assigning, with the ObjectDataSource?

I have a page where user can create their account. I have several validation controls on the page.When user clicks submit button the message box pops up with appropriate messges(as configured in validation summary). But once users clicks the OK button, then the form submits. Ideally it shouldn't do it?

I have a form in MVC3 that includes a check box to copy data if it is the same as a previous form. If the checkbox is checked, it populates the text box with the content from the hidden field. Here's a sample to illustrate what I'm doing:
[Code]....
When the box is checked, it calls FillInfo(), which uses DHTML to fill the TextBox called "ThisInfo" with the value of the hidden field "DefaultInfo."
Here's the problem: if the form fails validation (e.g. "ThisInfo" is a required field and is left blank), the hidden "DefaultInfo" box is getting cleared out -- which I DON'T want it to do. As a result, when the checkbox is clicked, it is copying empty data into the "ThisInfo" field.

Line 44, Column 69: there is no attribute "AlternateText" You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).
This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.
How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the <embed> element to incorporate flash media in a Web page, see the FAQ item on valid flash. I can't figure this out.

I'm populating a DropDownList using JS on the client and validating with a RequiredFieldValidator.This works fine on the client but the Page.IsValid consistently comes back false on the server.Is this because the selected value wasn't in the DropDownList when it was first served to the page?What's the easiest way around this? (I need to leave server validation turned on)

The following message appears in our log:The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request. alot has been written about this subject. However, I cannot reproduce this behavior, and I only find a couple thousand errors per day in the logs; so it's probably isn't that obvious.
The page in question has an UpdatePanel and loads one of three usercontrols depending on the querystring.Is there any known issue with some clients, or any other possible explanation?

What is the best way to debug a CompareValidator that always fails the validation? Is there any way to see what the values are that it's comparing to maybe get a clue as to what's going wrong?

I am uploading a JPEG image in an ASP.NET MVC web site.
The model validation fails in IE, but passes in Firefox, when I try to check the mime type of the
HttpPostedBaseFile.
So I debuged it and I found that when using Firefox the Mime type is "image/jpeg" as expected.
When using IE8 the mime type is "image/pjpeg".
Don't say that Microsoft invented a new Mime Type of JPeg images?

I'm working on an application form for a website which implements ASP.NET validation (including client side).
I have a requirement to display a message at the bottom of the page if the client validation fails. Something along the lines of "Please go back and check your answers".
The problem is, the submit button's OnClientClick event obviously fires before the client validation.

I'm trying to prevent data from loading on the page when its needed.
Currently, I check the IsPostBack bool to prevent loading data in my user controls which allows the data to be loaded when the page is initially requested.
However, if my page fails validation and the page is sent back to the user with error messages, my user controls no longer have data in them because the initial request was a postback.
One solution is to have a flag in every user control (IsFailedPostBack) to force them to reload their data. Is there a better way?

We're running a fairly large site, and a lot of our visitors have started using their Android based cellphones to visit the site. However when they try to login, we get an Event Validation error:
Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Does anyone know of a way to fix this, without disabling Event validation entirely ?
It isn't every single time they visit, but it is often enough that it's a problem.
Also we never get these on PC-based browsers (IE, FF, Chrome, Safari, Opera, etc.)
EDIT:
The page this happens on has no updatepanels, no custom __doPostback code, etc. It's pretty much vanilla with a simple LinkButton that causes the postback.
Also this error occurs on a bunch of other pages as well (Just found out about that now), so I doubt it's a lone design fault.

I've got an ASP.NET webform with asp:TextBox and asp:RequiredFieldValidator at the bottom of the page. If client side validation fails on form submit - the page scrolls all the way up.
I'd like to maintain the scroll position on failed client-side validation.
