ADO.NET :: Trying To Update Entities Childs Fail?
Dec 20, 2010
I am working on my first project with Linq to Sql entities/winforms, and I have little problems updating the entities childs in the main form, when I come back from the entity editor....
I have a list of people, and I can edit them or add new. The edited or new person opens in a new form and can have many addresses that can be added modified from the person editor and it opens a third form...
when I have finished edit the new address, so i return to the person editor and add the address, within the person entity context... so person.address.add(newAddress)...
Then I update the list of addresses, referencing: Datasource= foreach(address adr in person.addresses).And when I have finished editing the person i return to the mainform and save the changes from that entity.
_datacontext.save()
The problems I have are that if there is a new person, and I don't add addresses, the person saves without problem. But It doesn't do it if I add any address. With the updates I haven't any problem, they updates all, adds new addresses, but I can't remove anything with the person.addresses.remove(address)...

I'm having a question about an update method using SQL To Entities. I'm sending an object to the class and i'm updating him sucefully, but i need to specify each property of object instead of update in once. For example
[Code]....
In this case, i'm updating name, age and country sucefully but i want to use instead of update each property one-by-one, something like this:
[Code]....
So, the C = New should fill the C with all New values on properties, but this isn't work. To update an object, i've to update each property individual or can i update all in one like C = New?

I have a datamodel with a couple of tables. One of my tables have about 40 fields (I know that is a lot, but we have to keep the structure in place as we are upgrading a classic ASP project to MVC). Some of my Actions only updates 1 or 2 fields in my table.
Is there a way to create Entities, for instance, that only contains the contact details of the client table, and not any other details, and then another entity that contains only the address details. I don't want to submit the entire row when I only update telephone details, or the client's picture.

We are starting a new web based product in which we are planning to expose our business logic through WCF services. We will be using ASP.NET 4.0, C#, EF 4.0. In future we want to build iphone applications and WPF applications based on the services. I have been reading a lot about using POCO vs Self Tracking Entities (STE) and from my understand the STEs do not work well with the web scenario.

I have a table of products on my page, each product has zero or more colors, the colors are shown as a list beneath the product. After the colors I have a button to add a color. The button will do an ajax call with the parent product id to a controller which will return a JSON object with color information. My problem is where to store the product id in the DOM, should I put it in a hidden field and use jquery in the click event of the "add color" to get to it? What is the best way to do this?
EDIT: The page is initially rendered on the server so I don't want to use jquery to add the id's to the page.

Using the code such as found below, sometimes certain .PNG files will fail to load. While other images, nearly identical in size, never have any such problem. Build Action set to Resource. Why is that? Anybody figure it out? This is for a datagrid but I doubt the control has much to do with it. Probably certain .png files make Visual Studio 2008 choke because of some attribute set internally. But it's a mystery to me....anybody else notice this? # private void dGrid_LoadingRow(object sender, DataGridRowEventArgs e) { Employee emp = e.Row.DataContext as Employee; FrameworkElement ele = dGrid.Columns[4].GetCellContent(e.Row); string url ="http://localhost:7642/DisplayImageHandler.ashx?id=" + emp.ID; Uri imageUri = new Uri(url, UriKind.RelativeOrAbsolute); (ele as Image).Source = new BitmapImage(imageUri); } private void img1_ImageFailed(object sender, ExceptionRoutedEventArgs e) { Image img = sender as Image; // Display an image for error here }

I have a PageMethod that works perfectly well when it either (a) running in the VS dev server, or (b) deployed but marked with UseHttpGet=false.
What doesn't work, and is driving me mad, is having UseHttpGet=true and then deploying it to a test server (Vista & IIS7). It fails to call through the proxy with error code 404 coming back. But it works find if I set UseHttpGet=false.
I have gone through all of the basic stuff I can think to check, and as noted it works perfectly well on the dev box. So there must be something particular about full-blown IIS7 and its config that I am missing..
anything to check in the IIS manager that would cause this to fail? I've tried with forms authentication enabled and disabled, as a few posts mentioned issues with that.

I have reasonable experience programming for windows form programs in VB 2005, but I am new in ASP.NET. I have tried the file system website, and it does not seems to have a problem for me. However, when I was trying to create a website to run with IIS, it failed. This is what happened, to start, I chose location:HTTP on the "new web site" dialog box, and using browse button, I opened the "choose location" dialogbox. I choose "Local IIS" on the lefthand side. Then, I create new virtual directory, with the alias name "Test" and folder c:my documentweb site st (new and empty directory). Then I clicked the open button, it was still fine, where it returned to the "new web site" dialog box. However, when I clicked the OK button on the "New Web Site" dialog box, it comes up with this error:
"Configuring web site 'http://localhost/Test' to ASP.NET 2.0 failed. You may need to manually configure this site for ASP.NET 2.0 in order for your site to run correctly"
When I clicked OK, it does come up with a blank website, however if I run it, it will comes up with this error:
"Unable to start debugging on the web server. The server does not support debugging of ASP.NET and ATL Server application. Click Help for more information on how to enable debugging" but there is no Help button!
By the way, all the trials are done in VB2005/ASP.NET 2.0, we are trying to upgrade to VB2010 sometimes next year. The computer is running Windows XP.

What would make something fail in the IDE that is already in production?
I loaded just the aspx file into Visual Studio. it is just the file. It is used as a template on a CMS system (don't ask). The point is that I know that the paths work. So why does it fail in Visual Studio when I try to run it?
I have some asp.net code with a visual basic back end code file. It loads all the associated files located on the server that the aspx file mentions. But when I load the aspx file in Visual studio it says that a mentioned master page file cannot be loaded.

I've received 5 error reports from a site overnight.
XML Code:
Exception information:
Exception type: System.Data.SqlClient.SqlException
Exception message: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
It would seem that it's an issue with the server but it was reported to always occur at DomainModel.Services.ConfigService.get_companyName() which occurs when my config service asks the database for the company name using ByName("Company_Name")
Csharp Code:
private static Func<mvCmsContext, string, Configuration> _byName =
CompiledQuery.Compile((mvCmsContext context, string configName) =>
Is it just a server glitch or am I going to have to do some debugging today? I can't get it to fail no matter what I try.
edit - I just noticed one of the error reports was from a separate site. The first 4 were a local IP (ugh, probably the site owner) on one site between 11:00-11:04pm while the other was a chinese IP on my site at 11:07.

My masterpage has a loginStatus control to let users log out and it works very well on normal pages .Recently, I created a new content page associated with the mentioned master page. Such new page allows users to add textboxes dynamically through ajax asycpostback.
Unfortunately, loginstatus right now fails to work when i click it. I traced the process and i found out that the loggingout event was not fired when i click it.
I follow this video to make such "Dynamically add control" page.

I have several models that implement a array property using null object pattern in the following manner:
[Code]....
The problem is that any time I attempt to bind to a property of this type the DefaultModelBinder.CollectionHelpers.ReplaceCollectionImpl method wants to call ICollection<T>.Clear() and then ICollection<T>.Add() on the zero length array.
The real issue seems to be in DefaultModelBinder.BindComplexModel() method however. The method contains an explicit check for arrays and special handling to account for the fact that they don't support clear/add functionality. The problem is that the check stipulates that the array model must also be null. If it is non-null, normal ICollection<T> handling ensues which presumes support for clear and add. Can any one explain why the null check is there? It seems to me that either 1) the null check should be removed to permit replacement based binding to non-null arrays or 2) an explicit error stating that non-null arrays are not supported should be thrown.
I vote for the former. I can understand that in general, replacing an existing model with a refrence to a different model would be considered a bad thing. The calling code would not expect this in general and it could lead to hard to find bugs. However, in the case of arrays, if the calling code expects the array property to be modified at all, then I think the normal expectation would be that such modification would occur via replacement of the array.
