Is there an IsDirty property on EF data context that I can use with RelayCommand?

Posted By:      Posted Date: December 04, 2010    Points: 0   Category :WPF


I have a grid connected to a viewmodel and I'm using RelayCommand. At the moment, for the CanSaveAddressCommand I'm just returning true, but I'd like to disable the Save button to show that nothing has changed, and I also like to ask the user if they want to save before leaving the form. The viewmodel uses EF 4, so I thought maybe I should check the datacontext for changes. How do I do that?

private RelayCommand _saveAddressCommand = null;
public RelayCommand SaveAddressCommand
    _saveAddressCommand = new RelayCommand
     p => SaveAddress(),
     p => CanSaveAddress
    return _saveAddressCommand;

public void SaveAddress()

public bool CanSaveAddress
  //TODO: Check if datacontext IsDirty
  get { return true; }

Editing a poco's navigation property without the data context



I am using EF 4.

I need to set a navigation property. I could do something like this:

using (MyDataContext context = new MyDataContext())
    affaire.QualityID = 2;

The problem is that I want to do this in the code behind and I don't have any DataContext.
The logic for using a POCO would be just doing this:
affaire.QualityID = 2;
affaire.Quality = quality;

And later let the Bll load a context, attach the poco and save the changes. But I get an error message:
"The ObjectContext instance has been disposed and can no longer be used for operations that require a connection"
Is there any way for doing this scenario?

Automatically set a property value for a new record in a Dynamic Data application.


I have a SalesOrderItem table, and it has a UnitPrice column in case the salesperson wishes to override the unit price of the Product for that order item.

In an ASP.NET Dynamic Data application, what would be the best way to set that UnitPrice property on a new SalesOrderItem based on the standard UnitPrice for the product? In other words, when the user clicks New on the 'Items' screen for a sales order, the UnitPrice field should already be filled in with the normal unit price for the product.

This was originally asked by myself on StackOverflow at: http://stackoverflow.com/questions/3538234/automatically-set-a-property-value-for-a-new-record-in-a-dynamic-data-application

Storing data into property

Hi, I have written a property globally on page load i am storing setting some value into that property but on button click i am not able to retrieve the data. Is there any alternate way to save the data other than viewstate or sessionstate. Ex: Partial Class _Default Inherits System.Web.UI.Page Private s As String Public Property Test() As String Get Return s End Get Set(ByVal value As String) s = value End Set End Property Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then s = "Test" End If End Sub Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click s = "Champ" End Sub Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click MsgBox(s.ToString()) End Sub End Class

A general validation attribute for checking uniqueness in a linq to sql data context

I've been programming asp.net for, oh, a couple of days now. Here's a question I can't even begin to figure out for myself. I hope it's obvious from the code what I want to accomplish, and I have, but it's not pretty. Furthermore I'd like to use it on whatever table, whatever field, i.e. check the uniqueness of a value against a table and field I specify, passing it all into the attribute constructor. public class UniqueEmailAttribute : ValidationAttribute{    public UniqueEmailAttribute()    {    }    public override Boolean IsValid(Object value)    {        //not pretty. todo: do away with this.        var db = new CoinDataContext();        int c = db.Emails.Count(e => e.Email1 == value.ToString());        return (Boolean) (c == 0);    }}

UseExplicit property in infopath with form based context

Hi everyone, I have a problem with my infopath form. The context, user of the site mustn't have acces to lists that provision infopath form field. Administrator should have acces to these lists. When i test the useExplicit property of udc file for impersonate the connection to the list i have no problem ( all my account are local account) But when i try to integrate user from FBA, infopath form services don't take care of the UseExplicit property and try connect to the list with the credential of the connected user ( who don't have access to the list since only the user that i use to impersonate the connection have read acces). Here is my UseExplicit property :  <udc:Authentication>    <udc:UseExplicit CredentialType="NTLM">      <udc:UserId>dev\svc-reader</udc:UserId>      <udc:Password>password</udc:Password>    </udc:UseExplicit>  </udc:Authentication>    09/06/2010 15:06:50.46                w3wp.exe (0x09BC)                                      0x1A08 SharePoint Foundation                General                      

SSRS 2008 R2 Dataset Field Value Property Data Type not numeric

We're building SSRS 2008 R2 reports using SSAS as data sources.  There are several occaissions where the data types of certain dataset field values that represent cube measures are not numeric.  As such, when these fields are used in an aggregate function they throw an error.  Is there a way to remedy this in the dataset? Thanks for your help.

Data Annotation not triggering the client side validation when used on an overriden model property

Hi all, This is a saga from a post that was recently answered:http://forums.asp.net/t/1598187.aspxMy main problem is the lack of client side validation when we use a child model class, the server side validation works like a charm whether you use the virtual/override solution or the new attribute on the child class with the getter and setter linking the property to the base class's one.The client side validation does not work with none of the solutions presented below.This is a sample code of the first solution: [Serializable] public class DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] public virtual int? Year { get; set; } ... } [Serializable] public class BirthDateViewModel : DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] [YearRange(ErrorMessageResourceType = typeof(App_GlobalResources.Messages), ErrorMessageResourceName = "Validation_Range")] public override int? Year { get; set; } ... } This is a code sample of the second solution : [Serializable] public class DateViewModel { ... [Display(typeof(App_GlobalResources.Messages), "Date_Year")] public int? Year { get; set; } ... } [Serializable] public class BirthDateViewModel : DateViewMod

Data Binding to a Button IsPressed Property

Is it possible to create a binding on a button such that the boolean value is set to true when the button is pressed then is set to false when the button is released?
I tried binding to the IsPressed property but get "'IsPressed' property cannot be data-bound".
I am binding to an industrial OPC database and using WPF as a Human Machine Interface (HMI).

class contains non-dependency-property data members that are DependencyObject objects, you must also


I was reading the article Freezable Objects Overviewand came acrosee the statement

"If  your class contains non-dependency-property data members that are DependencyObject objects, you must also call the OnFreezablePropertyChanged method each time you change on of their values, even if you're setting the member to null. "

I quite do not understand the part about non-dependency-property data members that are DependencyObject objects. Can some one explain exactly what this means? If a data member is derived from the DependencyObject  class how then can the data member be a non dependency property?

I am also trying to locate some source code / project that overrides the OnFreezablePropertyChanged method, and have yet to find any on the interenet.

Cannot generate SSPI context. (.Net SqlClient Data Provider)


I have upgraded SQL SERVER 2000 standard edition server to SQL server 2008 with SP1 standard edition. No errors noticed. OS is Windows server 2003 with sp2, Service accounts are configured using domain user account, and mixed mode authentication is enabled.

Both windows and SQL authentications are working fine from the local (server), able to access all SQL server resources.

Server is accessible remotely using SQL authentication, but unable to connect with windows authentication, though user has local admin and SQL admin rights on the server.

Let me know any solutions for this. Appreciate your support

SSAS 2008 - The OLAP data source has no property fields available for this dimension


Last week I was able to view member properties for my Product Dimension in Excel 2010 pivot tables. Suddenly, without having made any changes to the dimension (for example, in the Attribute Relationships window of the dimension), those member properties are no longer available in Excel. I get the error "The OLAP data source has no property fields available for this dimension" when I try to select "Show Properties in Report" or "Show Properties in Tooltips" in the Pivot Table. At the same time, member properties are available for all other dimensions. I have also not made any changes to the data source connection in Excel and in any event, there is no option in the data source connection to enable or disable member property visibility. I am using BIDS 2008 and SQL Server 2008 R2 (10.50.1600.1). Does anybody have an idea why this might be happening?

TwoWay data binding to a specified index and property in a collection


Hello everybody,

my problem is, I can't bind to a specified item and property in a collection. The code:

    <test:ValueConverter x:Key="valueConverter" />
    <ContentPresenter x:Key="cont1" Content="{Binding Path=.[0], Mode=TwoWay}" />

A field or property with the name 'User_x0020_Name' was not found on the selected data source.


I am trying to bind the XML data to a datagrid from an XML file.  I don't know why I am getting the message: "A field or property with the name 'User_x0020_Name' was not found on the selected data source."

The "User_x0020_Name" field does exist in the XML file.  This is a portion of the XML file.
