I've got a simple form with some textboxes. These textboxes all have a RequiredFieldValidator. If field 1 is filled in I need to disable the RequiredFieldValidator of field 2 because only one of these fields is required. What is the best way to accomplish this?

I have to validate that the year entered must be less than or equals to the current year. I am using server side validators in ASP.Net and C#, and all validators are inside a validator group.
View 2 RepliesSo I've got entities set up with Entity Framework that have some properties of types String, DateTimeOffset and TimeSpan. For performing validation on the Strings, I've used fairly straightforward attributes like "[Required]" or "[StringLength]", and the control used is a textbox.
My issue now is for the DateTimeOffset and TimeSpan, I'm uncertain what control to use, but even more uncertain about what attributes to use to validate the input.
I have an ASP.NET form for currency exchange requests. There are two text fields there: amount-source and amount-target.

I'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?

View 2 RepliesI am beginner to MVC. I have created a View with dropdownlist, text box and text area. I didn't create a strongly typed view because these fields are not generating from the database.

How to create a Model class for these fields?

View 2 RepliesI'm struggling with ASP .NET Validators JavaScript issue. Following function (part of framework generated code) tries to access validatioGroup attribute value using control.Field syntax. It works fine in IE, however in FF that value is always undefined. Consequently, validation always passes and my validation scenario is broken... Is there a way to get round it?
function IsValidationGroupMatch(control, validationGroup) {
if ((typeof(validationGroup) == "undefined") || (validationGroup == null)) {
return true;
}
var controlGroup = "";
if (typeof(control.validationGroup) == "string") {
controlGroup = control.validationGroup;
}
return (controlGroup == validationGroup);
}
I have a Contact page, with 4 textboxes and 4 field validators. I made a RESET button to clear the text when pressed. But for an example: if i type on 2 textboxes and then press the RESET button, it tries to validate all 4 textboxes.

View 1 RepliesI have a page where I am using 2 update panels. The first update panel contains a form that has some validation tied to it. The second on has a simple form, but no validation.

I have an asp.net application with basic CRUD functionality. On a page where i am capturing customer details i have several asp.net validators to required fields. I have attached a JS confirm box on the asp.net save button for the form. The trouble is that when the user leaves required fields unfilled and clicks the save button, the JS confirm box comes up, when the ok button is clicked, the save method is called successfully and only after this happened do the asp.net validators fire and display that required information has been left out.
View 2 RepliesI'm using the built-in ASP validators on a few form elements. They work fine - if I click the submit button (a Button), validation occurs without postback and errors are displayed in a ValidationSummary. When that occurs, I also want to call a method in codebehind which changes the CSS of elements, switching their background color to red to reflect errors. I've tried to call this method using both OnClick and OnClientClick in the submit Button, but neither parameter seems to fire the method - client-side validation always takes priority, and a postback never occurs. Can anyone enlighten me?
EDIT #1 Using orandovs link worked alright for changing the element itself, but how about its parent? For example, in C# I'm doing:
foreach (BaseValidator validator in Page.Validators)
{
Panel panel = validator.Parent as Panel;
if (!validator.IsValid)
panel.CssClass = "error";
else
panel.CssClass = "normal";
}
Is there a way to get the parent control (which are all consistently Panels, so I know CssClass will exist) using JavaScript? Something like: $("#" + Page_Validators[i].controltovalidate.parent).CssClass("error");
I have an issue in my application . When I am calling a Javascript function OnClick of Submit button, the range validators on my page doesnt work.
