DataSource Controls :: Linq OrderBy With Nullable DateTime?

May 3, 2010

Is there a way to use the OrderBy command in Linq with a DateTime field using the Date portion only (without the Time Stamp portion) that is nullable such as in the following query?

var query1 = from myTable in MyTable
where myTable.EnteredDate != null
group myTable by myTable.EnteredDate into myOutput[code]....

Since myTable.EnteredDate is a DateTime field that can contain nulls, it does not support the .Date conversion call such as

Is there a way to convert the myTable.EnteredDate field into a date only string in the group by portion?

DataSource Controls :: Query A Nullable System.DateTime Column?

Apr 23, 2010

Am I going to be able to query (using LINQ to SQL) a database field with a type like the following "public System.Nullable<System.DateTime> Spouse_DOB"?

I'm trying to use the following code: [Code]....

and I get the error "'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)"

Is it because this DateTime column allows a NULL value (since everyone isn't married in my database)?

Error 1 'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)

MVC :: Nullable DateTime And DatePicker - Dictionary Requires A Non-null Model Item Of Type 'System.DateTime

Apr 1, 2011

I have a problem:

I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)

Here is view example:

<div class="editor-field">

@Html.EditorFor(model => model.BirthDate)

@Html.ValidationMessageFor(model => model.BirthDate)


BirthDate is Nullable<DateTime>

but during loading my View I get this exception

The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.

That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.

And I have Shared EditorTemplate:

@model System.Nullable<System.DateTime>

@if (Model.HasValue)

DataSource Controls :: LINQ To SQL Add's Extra Precision To DateTime - Causing Error

Apr 26, 2010

I am having an issue when trying to update a ModifiedDateColumn in the database via LINQ. I am setting the ModifiedDate property (which is a DateTime in both SQL Server and my code) using DateTime.Now. I am getting an error where LINQ is generating too many precisions when generating the SQL to execute. Here is what the LINQ is generating (see @p3 & @p5)


How do I get LINQ to only generate to only 3 decimal places?

C# - Orderby A HashSet In An Object In Linq?

Jan 7, 2010

I have a pretty complex Linq statement with multiple joins, but am having a problem with an orderby statement.

I think I can reduce the question down a bit, but will expand if needed.

First my object has the following properties:

myObject.ID This is a basic Int

myObject.BrandName This is my HashSet<string>.

I need to sort my Object by the BrandName using the lowest or highest value depending on if I am sorting ascending or descending.

DataSource Controls :: OrderBy Parameter Type In EntityDataSource?

Feb 26, 2010

I'm playing with an EntityDataSource and specifying a simple order by clause containing one column name, for instance "it.[DNS_NAME]".

When I run the following:


I get an EntitySqlException saying that @sort's type is incorrect. It is expecting a Transient.rowtype that matches one of the columns. What is going on here? Order by parameters don't really have a meaningful type other than a string in my opinion. When I try specifying DbType.String instead of TypeCode.String, the same error is thrown.

The exception:

'@sort' is not a member of type 'Transient.rowtype[(SOFTWARE_DSPL_ID,Edm.Int32(Nullable=True,DefaultValue=)),(COMPUTER_NAME,Edm.String(Nullable=True,DefaultValue=,MaxLength=64,Unicode=True,FixedLength=False)),(DNS_NAME,Edm.String(Nullable=True,DefaultValue=,MaxLength=64,Unicode=True,FixedLength=False)),(DIRECTORATE_NAME,Edm.String(Nullable=True,DefaultValue=,MaxLength=24,Unicode=True,FixedLength=False)),(OS_BROAD_CAT_NAM,Edm.String(Nullable=True,DefaultValue=,MaxLength=25,Unicode=True,FixedLength=False)),(OS,Edm.String(Nullable=True,DefaultValue=,MaxLength=64,Unicode=True,FixedLength=False)),(EQP_TYPE,Edm.String(Nullable=True,DefaultValue=,MaxLength=64,Unicode=True,FixedLength=False)),(EQP_PROP_NO,Edm.String(Nullable=True,DefaultValue=,MaxLength=10,Unicode=True,FixedLength=False))]'
in the currently loaded schemas.

How can I dynamically provide the column name to order by?

C# - Comparing Nullable DateTime's In

Nov 17, 2010

I am a c#/ developer and I am having to work on a VB/ I started out with VB.NET but after years away from it I'm getting confused with the syntax.

I have two variables

Dim originalDate as DateTime?
Dim newDate as DateTime?

Both nullable datetimes, originalDate is a nullable date I am getting from the database and newDate time is set in code, I need to compare them, they can either both have dates, neither have dates or one have and one not.

I have a bit of code as follows:

if origEndDate = origEndDate then

When both origEndDate and origEndDate are "nothing" this statement is false (well when I run it in the watch window it comes back as nothing)!

I don't understand why this is the case because I was under the impression doing an "=" compares the two values and as they are the same surely it should be true?

What syntax should I be using as in C# I can do the above as so:

if (origEndDate == origEndDate) { }

and it will come back as true.

Nullable DateTime Parameter Never Bound When Calling Action

Sep 20, 2010

I have the following function signuture:

public JsonResult PopulateGrid(int page, Guid? accountId, Guid? systemUserId, Guid? branchId, DateTime? fromDate, DateTime? toDate, HomeVisitType? homeVisitType)

Every single parameter is bound just fine except toDate which turns out to be always null. When inspecting the Request.QueryString["toDate"] it retrives the right value which is 30/09/2010. It seems that DateTime expects another format when binding.
What is the right format?

MVC :: Nullable DateTime Give Invalid Modelstate If Null?

Mar 19, 2011

Got a nullable datetime member on my viewmodel.the moment it hit my controller action, the viewmodel's modelstate allready are invalid (because the member is null) that works? (using MVC2)Basically my viewmodel have a social security number, passport number and passport expiracy date.If the ssn is entered, I want to ignore the two passport related fields, so I made the expiracy date member nullable.

Like all other viewmodels in this app, each model have it's own validation function that will do validation, and in there I add an error that the date is required or not valid (if using passport number). mvc itself should not care about the date at all.I dont want to give the date a default value, because then the date will show when the form loads, and it must be an empty field (unless I already got a date of course.

C# - The Type Arguments For Method System.Linq.Enumerable.OrderBy Cannot Be Inferred From The Usage

Jan 28, 2011

I'm trying to follow the demo from this link to add a jqGrid to an MVC app.

I have a table named Companies that I'm trying to display in a grid. A Company simply contains an ID and a Name.

I'm running into an error in my controller function:

public JsonResult DynamicGridData(string sortIndex, string sortOrder, int page, int rows)
int pageIndex = Convert.ToInt32(page) - 1;
int pageSize = rows;
var companies = companiesRepository.Companies.OrderBy(sortIndex + " " + sortOrder).Skip(pageIndex * pageSize).Take(pageSize);
//Error here

I'm getting an error on the line that is calling OrderBy():

The type arguments for method 'System.Linq.Enumerable.OrderBy(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

I really have no idea what the error means, and I haven't been able to find an explanation. I'm not sure what is causing this error on a simple OrderBy function.

MVC :: Unable To Get DataAnnotations Client Validation And Nullable DateTime Property

May 12, 2010

I am having a problem with the Client Validation not firing when I have marked a nullable DateTime field as [Required] and the value of the field is null. (It is actually stopping ALL client validation on the page working - not just the DateTime field).

Interestingly enough, once a post back has been done and the error picked up on the server, the client validation starts working.

Also if you set the date to a none null value (see commented out line in the controller) it will also work

I have replicated this behaviour in a small test project (this is deliberately very Noddy - just enough to replicate the problem)

Am I doing something fundamentally wrong or am I looking at coding some sort of work around here? (I realise that a Required nullable field sounds like a bit of a oxymoron, but I wanted to present the user with a blank field which they must then fill, not one pre-populated with an arbitrary date value)

DataSource Controls :: How To Call TableAdapter Stored Procedure With Nullable Parameter

Jun 24, 2010

I spent about 60 minutes sifting through search engine listings trying to figure this out and couldn't find an answer, so I decided to make this post for others.

Situation: Using a Stored Procedure to insert a row and return the new row ID, explained here. In my case, I used the Idenity_Scope to return the new row, like so:


Next, following steps as described in link above, went into the dataset XSD page, configured the table adapter to use this stored procedure. By default, it wanted my return value to be set to some value, but I set to allow Null (makes sense, since I don't want to pass the value in, I want to get it out, so it should be null to begin with).

Problem: Where I ran into an issue was in the method to call this stored procedure. The intellisense displayed the prototype it was expecting, basicly like this:

DataSource Controls :: The Null Value Cannot Be Assigned To A Member With Type System.Decimal Which Is A Non-nullable Value Type

Dec 22, 2010

I am making a website to store invoices so i can mail them to clients. So i got a table for clients, invoices and one with invoice products/services. When an invoice has no products/services added to them and it returns null i get the error "the null value cannot be assigned to a member with type System.Decimal which is a non-nullable value type."

I just started with linq. Before i always used mysql. Mostly i just had to call data from 1 table so forgive me if my linq query isn't really correct.

Dim invoices = From i In db.invoices _
Group Join p In db.products On Equals p.invoiceId Into invoiceProducts = Group _
Select New With {i.client.naam, i.titel, (From iP In invoiceProducts Select iP.prijs).Sum}

i show the client's name, the title of the invoice and the total amount the clients will need to pay for products and services.
