I've a radio button list which expands a section of a form depending on which item is selected. While I've got this working, how do I switch off the validation for the (additional) form items when the form is not in the expanded state? Do I group the expanded section form control validations and turn off that validation group? Is that the best way to do it and if so, how do I do that in C#.net?

View 1 RepliesI have two fields in a form that a user can only put either 0 and 1. Both cannot have same value. if first amount is 0, the second amount must be 1. and someone show me how to write a validation in Javascript that I can call it from JS.file At the same time, I want to be able to create the same validation when the form is generated dynamically. so the Javascrip validation has to be created from code behind once the input form is created. If you have any link in the site that can show me lots of this kind of example, I want to learn this stuff.
txtAmount1.Text =0
txtAmount2.Text =1

I was using a view to create an object for my specific project, but now I have to adapt this to another requirements, such as the creation of this object must be integrated in the creation of another one. The thing is, that this object must be created before starting to create the other one, and the way of doing it will be poping up a modal dialog box with JQuery with the form to create it. I've got to adapt the creation and it works fine, except for the validation messages. It is made in the controller like :

I'm using the latest RC with asp.net mvc 3, and have turned on unobtrusive javascript validation and added the necessary scripts to the page. All of the validation works perfectly, but when I try to submit the page, it simply doesn't post. If I turn unobtrusive javascript off in the web.config without making any other changes, everything works perfectly fine.
Here's my scripts I'm using:
<script src="@Url.Content("~/Scripts/jquery-1.4.4.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
I have applied validation through JQuery Validation Plugin on my page. The validation works fine but once the Clear button is hit to clear out all the fields on the form, and then the save button is clicked again, the validation doesn't fire and the form gets submitted. I have called the following javascript function on click of Clear button to clear out all the form fields :-

The Clear button is on a ChildPage and ResetForm function is on the MasterPage.
I want to validate some asp.net textboxes with the jQuery Validation plugin found at[URL], but it appears that the elements must be between a form tag. If I have just a couple elements, I would hardly call that a form, so I would rather not have them wrapped inside a form element. Is there a way around this? Also, if I have two buttons on the form, a cancel and a submit button and I want the form only to validate when the submit button is clicked, but not the cancel button, how is this accomplished?
View 2 RepliesI have a simple form on an ASP.NET MVC site that I'm building. This form is submitted, and then I validate that the form fields aren't null, empty, or improperly formatted.
However, when I use ModelState.AddModelError() to indicate validation errors from my controller code, I get an error when my view is re-rendered. In Visual Studio, I get that the following line is highlighted as being the location of the error:
<%=Html.TextBox("Email")%>
The error is the following:
NullReferenceException was unhandled by user code - object reference not set to an instance of an object.
My complete code for that textbox is the following:
<p>
<label for="Email">Your Email:</label>
<%=Html.TextBox("Email")%>
<%=Html.ValidationMessage("Email", "*") %>
</p>
Here's how I'm doing that validation in my controller:
try
{
System.Net.Mail.MailAddress address = new System.Net.Mail.MailAddress(email);
}
catch
{
ModelState.AddModelError("Email", "Should not be empty or invalid");
}
return View();
Note: this applies to all of my fields, not just my Email field, as long as they are invalid.
I am using Accordion with multiple AccordionPane. Each AccordionPane has a form tag that contains asp controls such as dropdownlist and textboxes and buttons to submit or cancel. Each asp control has a requiredFieldValidator assign to it. However when a i am in a particular AccordionPane to submit the form, the validator for other fields in other fields is highlighted preventing me from submitting.

View 6 RepliesHaving an issue with some form validation. Everything works great right up untill I add a postbackurl to my button. Any ideas on how I can make my form check validation before the postbackurl is used?

I have a page that I'm working on that I trying to do the following with:
1. Name a file upload.txt (with codebehind) every time a file is uploaded with a user pressing a submit button.
2. Validate that the file is a .txt file (again with codebehind)
3. Lastly, once the user presses the submit button, that a sql query is run.
I realize that .xml is the proper way to do this but as I'm new to .net, I want to do this with simply inserting the sql query into the codebehind. Here is my codebehind thus far: [Code]....

View 2 RepliesI'm working on a very dynamic site build at the moment. What I'm trying to do is creating something like a survey that can be created dynamically from a control panel. In the control panel you add input fields (these are saved in a database), what the user then see is a form that I generate from the database. So if I add 3 input fields to the database the survey will contain 3 fields. If I add 20 fields the survey will have 20 fields.
Now my problem is that I want to validate these fields, and I would like to be able to hook me in with the standard validation flow. I can't create a Model with validation rules since the number of fields and their names are dynamic the only thing I know is what kind of data that is expected in every field (this rule is found in the database). In an ordinary case I would get the automatic highlighted fields that are not valid and so on thanks to the built in validation flow with ValidationResult and so on.
So the question now is can I somehow simulate parts of the validation and then hook me back in with the validation result, and if not valid, the form prints the error messages and fill the fields with the data that was given?
I am a completely new to ASP but have been given the task of creating some simple forms for my employer. how I could validate the Email, Website fields? And also make the Post Code a required field?

I have added the .dll file in my project's BIN folder and for Matt Gibb's solution I have also added the tagMapping code to web.config file. But for both of the solution, when I ran the project I noticed it doesn't have any effect on the validation controls.
I have a form for the user to add a Contact's details. Within this form I have fields to enter telephone, mobile, fax numbers etc.
Each have a separate textbox for country code, area code and number. Basically, what I want to do is have validation on these fields so that all or none of the textboxes are filled.
So if the user just adds a number in they are required to enter also the country code and the area code. Or if they don't enter any of the details then the validation will not kick in.
