How To Make Validation Optional For A Complex Type In Mvc
Feb 23, 2011
I want to display an editor for a type User. User contains a field Address of type Address. I made an editor template for the type Address so that it is reusable.
I don't want the field Address to be required for creating a user. But some fields are required for Address, for example country, state etc.
I want to validate Address if I receive any data for it, if I don't receive anything, then I don't want to return any validation error to the UI for Address. I would return only validation errors for User then.

I have made an entry field required somehow but I'm not sure how. When editing a tag, the tag owner entry field should be able to be empty.I have set "allow nulls" in the database table:Does anyone know how I can fix it? To be clear, I want the above form to be submitted without requiring a value for tag_owner.

I have a Page.cshtml similar to the following (that does not work):
@{
Layout = "../Shared/Layouts/_Layout.cshtml";
var mycollection = (ViewBag.TheCollection as IQueryable<MyCollectionType>);
}
<h2>@ViewBag.Title</h2>
content here
@if (mycollection != null && mycollection.Count() > 0)
{
@section ContentRight
{
<h2>
Stuff
</h2>
<ul class="stuff">
@foreach (MyCollectionType item in mycollection )
{
<li class="stuff-item">@item.Name</li>
}
</ul>
}
}
As I said, this does not work. I want to not define the section if there's nothing in the collection. Is there any way to have something like this work? If not, what are my other options? I'm very new to this Razor ViewEngine. Edit In my layout i have:
@if(IsSectionDefined("ContentRight"))
{
<div class="right">
RenderSection("ContentRight")
</div>
}
what i don't want is the div to output when the section is empty.

I'm been working on a GetRuleViolations() method for my User class, but I'm getting a little hung up on on something:
What happens when different actions require different business rules?
My User table has the following columns: Id, UserRoleId, Username, and Password. Several actions involving User are possible (create new user, edit user, set/reset password, and log in), and the business rules for each are not always the same.
For example, when users log in, they are required to enter a password, but when admins create a new user, entering a password is not even an option. And in the case of setting/resetting a password, the password needs to be entered twice, and the two values need to be an exact match. What is the best way to handle this complexity? Is there some kind of design pattern to allow the right GetRulesViolations() method to be selected for the right circumstance?

I thought this would be easy and maybe it is but it's eluding me.
In an action filter (MVC 2) I want to add/edit one of the parameters for the type I'm passing to my action method.
I have an action method:
[Code]....
Bar is a simple class for viewData:
[Code]....
In my BarFilter action filter OnActionExecuting method I want to add a value for paramA which is not set by the view so that Bar will be fully populated in my Foo action method. I've tried various methods of adding values to ViewData, ModelState, Model etc. but I always get a null returned in Foo.

I feel like I am fighting against the current when I develop ASP.NET Webform apps. I frequently run into the same problems, and while I eventually find some kind of workaround i'm never fully satisfied with the results.
Here is an example of a typical problem:
The design requires a grid or grid-like result set. This result set is pulled from a database, however, there are additional controls on each row that are not data bound, but their contents are used to insert data into other records.
A good example of this would be displaying a list of products, then adding selected products to a shopping cart based on values entered into quantity fields, and options selected per product. Throw into the mix that you have to allow multiple lines to be added to the cart at the same time, and it starts to get more complex.
Let's add to that mix that you can't select certain products together (mutually exclusive), that you can only select a certain number of one product, but not another, that prices may change while the user is selecting their items, that you you get an overall discount per item based on quantity purchased (both per item and overall order), that you are using a line of credit and cannot exceed the line of credit, nor can you buy more of a given item than an arbitrary amount set in your account or in the product by your account representitive (think certain over the counter medications that the government limits how many you can buy), etc.. etc.. etc..
What starts out as a simple grid with an add to cart becomes a hopeless mess of business logic, which then of course requires validation and notification to the user of various errors in their choices.
How does one deal with very complex data entry schemes in asp.net? How do you even begin to design a piece of software to do all this?

consider classic example: Product and Category editing Product in dropdown Id of Category is selected - Category mapped as object with all fields empty except Id when submitting Product edit form - validation gives an error: "Category name is required" (I have Required attribute on Category Name property)
How deal with such errors if I want to use built-in validation (
[Code]....
Writing custom data binder which would fill all such id-only-objects with values from database comes to mind.
upd: I did small research of mvc code and found out that validation happens before binding - so this solution would't work.

I have a question regarding validation of drop-down list values. I have a view that is bound to a view model type called ReservationData.
This object contains a property CustomerVehicles of type List<VehicleData>. VehicleDatahas two int properties VehicleMakeId and VehicleModelId.
On my view I am trying to loop over the number of items in the CustomerVehicles collection and displaying two dropdowns for each, a vehicle make dropdown and a vehicle model dropdown usingDropDownListFor.
When I try to submit and validate I do not see any validation errors displayed on the screen.
Just in case you are wondering I have added a ValidationMessageFor for each dropdown as well. I am not sure if this is an issue with the structure of my view model and its complexity and how the controls need to be named or how the ids need to be set.
Here is the code for the looping over the collection:

what i want to do is to set up different validation summary for different type of validators. for example, for required field validators, if user leaves some required field blank, it shows that "You have to fill in mandantory information, indicated with a star"
and if some format is wrong, it shows that "format is invalid"
right now, i set all requied field validators' text to be a star, and leave error message to be blank. so that the validation summart will only display the header message. that is what i need. what i dont know is how to separate regular expression into another summary.
i think the validation group property requires multiple buttons. however, i only want one submit button, and this is where i got stuck.

Using this code, I can get a very cheesy red lettered message.
<form id="frmValidator" action="required.aspx" method="post" runat="server">
Enter Your Name:
<asp:TextBox id="txtName" runat="server" />
<asp:RequiredFieldValidator id="valTxtName" ControlToValidate="txtName" ErrorMessage="enter your name!" runat="server" />
<br />
<asp:button id="btnSubmit" text="Submit" runat="server" />
</form>
Is there some way for me to have a green icon (I have that image so I imagine I just have to reference it) sort of fade into existence beside the control?

I'm trying to let the user download different documents where the data is stored in an SQL DB. In firefox, the filetype is correctly read, but not in IE. I'm trying to do this without having to set the ".pdf" or whatever extension the document has, because I haven't got that information. I only have the filetype.

I'm having trouble with the implicit type validation for model properties. The validation/error messages (for numeric fields explicitly) are printed in English (I want them to be printed in Swedish). Does anyone know how to override those messages? Or can I turn of implicit type validation? The error message I'd like to translate/localize is "The field {0} must be a number."

I've seen various controls in ASP.NET with "collections" of objects, which you can use markup to define. For example:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<Triggers>
<asp
/Triggers>
</asp:UpdatePanel>
In the above example, you can add any number of triggers, and they can be of any type that extends UpdatePanelTrigger. I'd like to do something similar, but with only a single item instead of a collection
