MVC :: DataAnnotation Attribute For Integers?
Jan 11, 2011Is there an out-of-the-box DataAnnotation attribute that checks if an integer is greater than a certain value?
public Model
{
[GreaterThan(0)]
public int MyVal{get;set;}
}

View 3 RepliesI am developing a simple application. I have completed.
1 - Using Respositary Pattern
2 - using DataAnnotation for validation.
3 - Selecting, Creating, Updating and Deleting.
My Questions.1 - I have extra BL validation. Should I create Service layer or use that in Partial Class where my DataAnnotation is?
I dont want to use DataAnnotations in one class and other BL validation in another class. Is there a way to combine both or Should I use those separately. Confused here? Any examples to implement BL.
2 - I have lots of Calculations to run once record is reterived and insterted. Where I put these calculations? Should I make extensions and call in controller or Methods in separate file. Any clean approach.
3 - Can I use Repositary Pattern and Service model in ASP.NET webforms with ADO.NET, Entity Framework and Linq to sql?
4 - I don't know id this is stupid question. Can we use ADO.NET with DataAnnotation somehow in Webforms and ado.net with mvc?.
In a vb.net application I have a set of integers currently stored in multiple Arraylist (But this could be something different if required)
al1 = {1, 2, 3, 6, 7, 9}
al2 = {2, 3, 4, 9}
al3 = {2, 3, 19}
I would like to get the set {2, 3}
I thought about using LINQ to join the list, but the number of Arraylist can change. I know I can always loop through everything and check if an integer exsist and keep track of it, but I thought there might be an easier way?
I have 4 drop down menus labeled as with static input as
0-9; JobPerReview1 JobPerReview2 JobPerReview3 JobPerReview4
If for choice the user selects the following;
JobPerReview1 = 3JobPerReview2 = 0JobPerReview3 = 5JobPerReview4 = 9
I would like a function/ script to sum the total inputs as an integer or if that's the correct term for it. So it would calculate something like thisJob
PerReview1 = 3 summed as 1JobPerReview2 = 0 summed as noneJobPerReview3 = 5 summed as 1JobPerReview4 = 9 summed as 1
I would also like a total box labeled "NOF (number of factors)to calculate the selections such as;
NOF = 3
This is starting to be mind bugling function
getItems(){var items = new Array();var itemCount = document.getElementsByClassName("items");
var total = 0;var id= '';for(var i = 0; i < itemCount.length; i++){id = "p"+(i+1);total = total + parseInt(document.getElementById(id).value);
} document.getElementById('tot').value = total;return total;
} getItems();
function getItems() {
var items = new Array();

PropertiesMustMatch fails because for some reason it's hit PRIOR to "Required" property. How come??
how do you set the order or validation so that Required is hit prior to any custom validation?
I have a class like so:
[Validation.PropertiesMustMatch("Password", "ConfirmPassword", ErrorMessage = "'Password' and 'Confirm password' do not match.")]
[Validation.ValidateMemberUsername("Username", "Oldusername")]
public class Member

I am having trouble with the with mvc2.
I am using the Entity Framework as my ORM. I have used the POCO Entity Generator to create POCO objects. I moved the generated objects to a separate project. I followed steps outlined here(Tutorial). This is my project structure
Sports.Data - Entity Frmework and Data Access
Sports.Entities - The poco objects generated and buddy classes
Sports.Web - The web application
In the Sports.Entities project I have created buddy classes for the generated pocos.
The problem I am having is that the attributes are being ignored by the mvc. The validation is not working and the correct label text is not being displayed. Instead of 'Shirt Size', 'ShirtSize' is displayed.
Here is the code.
<div>
<%: Html.LabelFor(m => m.Player.ShirtSize)%>
</div>
<div class="editor-field">

I want to populate a Dropdown list from divisons of a figure in my projects database
for example database figure 50
I want the dropdown list to show 5,10,15,20,25,30,35,40,45,50
The database figure wont always be the same.
how would i go about doing this ? esp the populating of the dropdown list itself based on the way i want to show it.
Been Googling about this for a couple of hours but haven't hit on the solution yet. This is an ASP.NET 3.5 app connecting to an MS SQL 2008 backend. The app uses a strongly typed dataset with ad hoc queries in table adapters. The object data source on the markup page will have one parameter that will accept a string of comma separated IDs. I need to feed that list of IDs to the WHERE clause in a query to pull each of the specified records. This is trimmed down version of the query:

I am sorting the grid using DataView's "Sort" property. I am passing sort expression and the order in which the grid is to be sorted(ASC or DESC). But the problem is, since the column on which I am sorting the grid is listing the intergers, the sorting is happening as if it is a string. But I need integer sorting rather string sorting on that column.
The grid displays below as ascending order(string sorting)
55
77
8
But I need the columns to be displayed like this(Integer sorting)
8
55
77

How can I maintain using data annotation attributes for validations in mvc3 different requirement for edit and create in an elegant manner. I have an different edit and create requirement.
I've got a view with 2 forms on it - one to login and the other to register. My problem is that the client-side validation from MicrosoftMvcValidation is firing regardless of which form I submit - because my forms are rendering the inputs with the same id e.g.
<input id="User_Email"
name="User.Email" type="text"
value="" />
How can I change the generated forms to create different id's for the inputs in such a way that the validation works?
I'm using a strongly-typed view with a model with this property:
Model property:
[Required(ErrorMessage = "Please enter an email address")]
public string Email { get; set; }
First form:
<% using (Html.BeginForm("LogOn", "Account")) { %>
<%= Html.ValidationMessageFor(m => m.User.Email) %>
<%= Html.TextBoxFor(m => m.User.Email) %><% } %>
Second form:
<% using (Html.BeginForm("Register", "Account")) { %>
<%= Html.ValidationMessageFor(m => m.User.Email) %>
<%= Html.TextBoxFor(m => m.User.Email) %><% } %>
My second form produces id's identical to the first form which is causing the problem.
Is it possible to specify the difference in the Html helper on the view or do I need to provide 2 seperate models somehow? I'm a bit in the dark.
I would like to use the IEnumerable function Intersect() to combine a few list and get the similar integers from each list. The problem I'm faced with is that I don't know how many list I will need to compare.
Here is an example:
A{1,2,3,4}
B{1,2,3}
C{1,2}
results = A.Intersect(B).Intersect(C)
This works great, but the next time around I may have a D{1,2} next time I come across the function.
I'd like to use the Intersect method, but I'm open to new ideas as well.
I've got a report w/ grouping and a running total field. The running total is the sum of 'n' integer values, however, when I display the running total field it displays a floating point value. So for example, two rows have 10 and 15, but the the running total displays 25.00. Is there a way to display this result as an integer? I tried using a formula field w/ the 'Int', 'Truncate', and 'Round' functions, but nothing seems to work.

I have a table that displays a user control on each row. The user controls are strongly typed to a viewmodel which contains DataAnnotation style validation. If one of the rows has invalid data entered (lets say the 3rd row) the data annotation validates display agains the first row/user control.How do I get the data annotation to show against the relevant user control?
