I'm using MVC 3 RTM, client side validation has been disabled.I have a simple model with one integer field.Server side validation does not accept numbers including one or more thousandseparators.
It shows: "The value '1,000' is not valid for QuantityInStock".It does not matter what culture I use. Both "1.000" and "1,000" are never accepted.

I'm currently stuck with a problem with MVC2 RC and validation on a dropdownlist :
I have a page with some fields and a dropdownlist. The dropdownlist is not a mandatory field so I would like to save a null value into my property.
Unfortunately, I can't validate my page with a null selected value, because when I look into the modelstate just on the first line of my action, I've already an error telling me I must choose an item.
Is it normal working of dropdownlist validation or is it a bug ?

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();

I've build this function:
I like to convert 1234,222 to:
1.234,22
But what happends below is he converts it to 1.234, so verything after the , is gone. How can i change this function so it works correctly?
Also if the number is 1.234,248 the result should be 1.234,25 , so just 2 numbers after the ,
public static string AddDigits(string source, int digitaldigits)
{
System.Globalization.NumberFormatInfo format = new System.Globalization.NumberFormatInfo();
format.NumberGroupSeparator = ".";
format.NumberDecimalDigits = digitaldigits;
decimal i = decimal.Parse("1234,222");//decimal.Parse(source);
//int i = int.Parse(original);
string str = i.ToString("N0", format);
return str;

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'm trying to import csv file that that uses double qoutes from the text qualifer but doesn't use any qualifiers for the numbers or null fields. The data looks like this:
1,"Jack","Smith",23,
2,"Susan","Smith",,
3,"Mike","Smith",,
2,"Chris","Smith", 18,
The command I'm using is:

I keep getting "Bulk load data conversion error (type mismatch or invalid character for the specified codepage)" when it tries to insert null from the csv into a numeric data type.
I tried changing the codepage, datafiletype, fieldterminator, formatfile but I still can't get it to work.

I have an AJAX NumericUpDown Control that takes a decimal. If I put in 1.30, it removes the zero. I do not want to remove the zero, it must remain at 1.30.
A demo of this can be found here: [URL]
For example, enter 1.30 in the text box then tab out or click somewhere else. The zero is removed.

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

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.
