MVC :: Validate Entity With List?
Apr 27, 2010Let's say we have a entity to add - an Invoice with multiple Lines
public class Lines
{
public string ObjectName;
public string Color;
}
public class Invoice
{
public string DocumentID;
public DateTime InvoiceDate;
public List<Lines> lines;
public string Observation;
}
The Lines is valid if and only if it has ObjectName and Color
Now, when in AddMode , the requirements are to show enter a new Invoice with 10 Lines by default .
This was easy (binding to an object that contains list, right?) - but in validation mode, the ModelState.IsValid is validating all my 10 lines - regardless if the user have been entered only 2 lines.
I have tried to remove the empty lines by writing a Binder for Invoice, inheriting from DefaultModelBinder and removing the empty lines ( those for ObjectName AND Color both nulls or empty ) .But, no matter what overriding method (CreateModel , BindModel ) I have used , no success. The binding model occurs first.
I have tried to do ModelState.Clear() and ValidateModel(invoice) in the controller. But ValidateModel is not validating "sub-properties of complex properties" - see comments from
[URL]
If you know how to either :
a) re-validate all properties (including for complex object)
b) modifying the model before ModelState grab errors
c) ?
(I can not debug with MVC2 source code - but this is another post...)
Validate A List Of String?
Jan 31, 2011Data annotation to validate an inbound model in MVC:
public class ValidNumber
{
[RegularExpression(@"^d+$", ErrorMessage = "*")]
public string number { get; set; }
}
Would I need to create my own class to validate a List<string> or can I do something like this? What code could I write in C# to add a Regex validator for a list of string?
public class ValidNumberList
{
[RegularExpression(@"^d+$", ErrorMessage = "*")]
public List<string> numbers { get; set; }
}

C# - Validate Dropdownlist Selectedvalue Against A List From Static Property?
Oct 4, 2010I am using javascript to validate user input on my aspx page. I am easily able to validate textboxes and dropdown list for differenet scenarios.
Now, on one of my dropdown lists (for country), I need to check if it is an allowed country or not for a particular service. I have stored the valid country list in a static property. Is there a way to validate my dropdownlist selected value against that static property?
function validateService(source, args)
{
var country = document.getElementById('<%= ddDestCountry.ClientID %>');
var service = document.getElementById('<%= ddService.ClientID %>');
// Get allowed country list from my static class
var countryList = document.getElementById('<%= StaticProperties.EUCountryList %>');
if (service.value == "P")
{
// I want to do something like this
if (!countrylist.Contains(country.value))
{
args.IsValid = false;
}
else {
args.IsValid = true;
}
}
return;
}
Update(Additional Information): The static property is read-only so it cannot be tampered with from the page.

View 1 RepliesForms Data Controls :: How To Validate A Text Box (if It Is Blank) Inside A List View Row, On Selected Index ?
Feb 8, 2010i have a drop down list and a text box, inside a listview row (and this is a repeating layout). i populate each dropdownlist with same contents ( these contents/items come from a custom collection object).
i have added a required field validator in the listview's item template, that has its validation group = the validation group of the drop down list, and validates if the textbox is blank or not. this validation takes place on the selected index changed of the drop downlist for that row.
1. on selected index changed, EACH dropdownlist validates only its corressponding textbox perfectly (which is what i want)
but if i enter some text in one of the textboxes after doing 1, the dropdownlist for THAT particular row, assigns the correct value to the text entered. but for other rows (for which i changed their corresponding ddls to test the required field validation and for which the text boxes are still blank), their ddls by itself assign the values to the blank text without validating.
markup of code for listview is [Code]....
code behind for the ddl selected index changed is [Code]....
method GetIndexFromId retrieves index of the custom object inside a collection depending on the Id (which is a property) of the object.
i notice that the ddl selectedindexchanged is being hit as many number of times as many rows i change (i.e as many ddls in different rows i change to check the required field validation)
JQuery Validate Plugin MS MVC Won't Validate?

Web Forms :: Clicking The Label Of A Dropdown List - Resets The Selected Value To The First Item In The List?
Feb 17, 2010Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.

How to prevent this one. It should be on PRIMARY Only.

Javascript - MVC List With JQuery - Links - View To Display A List Of Products
Nov 5, 2010I am using a strongly-typed view to display a list of products, where every li-element gets a unique id:
<ul id="product-list">
<% foreach (var item in Model.Products)
{ %>
<li <%= "id="product_" + item.Id + """ %> >
<div class="item">
<%= item.Name %>
</div>
</li>
<% } %>
</ul>
Now I want to attach to the click-event of every single li-element, so that if the user clicks on a div-element, detailed product-informationen should be loaded asynchronously into a details-pane. I know how I can use jQuery to invoke an action-method ajax-style and also how to display the json-result which contains the product-details, BUT I have no idea, how I could attach the onclick-event to every single div, so that I can use the productId to load the details.
