Child Properties Not Initialised Automatically With RIA?
Feb 2, 2011
Within my project I have created an Entity Data Model, complete with relationship links between the various tables. I notice when I do so, Visual Studio automatically creates a property named after this link.
I have then generated a Domain Service Class based on this data model, and once again within this a property is generated representing the link, ie within my ChemicalApplication class there is a Chemical property of type Chemical.
The trouble is, within the silverlight client, I can access the ChemicalApplication data object no bother, and can see the ChemicalApplication.Chemical property, but as soon as I try to access it, I recieve an error that the property is not initialised.
Do these auto-generated child properties not automatically initialise? If not, how do i manually assign a value to them within the RIA Domain Service?

If i have N numbers of classes on each of them i am declaring for example property which contains some app setting values from config file.
public static IAppSettings AppSettings { get; set; }
I want to populate this property automatically when class is created.
I am thinking to achieve this goal using StructureMap.
I want to "say" somehow only in one place, that if class contain this property populate it.

Can anyone give me an idea how to go about this? I've tried searching but most articles talk in the context of web controls...

Consider this abstract class
public abstract class Foo
{
public Injectable Prop {get;set;}
}
i have an application that i want to enhance and simultaneously refactor for simplicity.
I have over 100 classes that call some same stuff (e.g Class Injectable) and i am thinking that this behaviour can be abstracted and set to a base class, and everybody will inherit from this base class so as to remove copy/paste code.
However, i want to avoid copy/paste code in the spring configuration file by defining an Injectable object and then define a child object foreach and every class that inherits from Foo.
I am looking for a way to set the abstract class's properties and then all child elements to automatically get them via configuration. I want to avoid to make the abstract class like this:

I am having a meltdown over something that seems so simple and yet isn't working. Here's my scenario.
I have an object structure of tEvents, which contains properties of an event like a run of concerts. tEvents in turn contains an entity set of tEventOptions, which include properties like EventDate, Cancelled etc. I would like to query a list of tEvents using properties of the tEventOptions, for example filtering by date.
My pageis using a calendar object to show event dates. So I am trying to find if any tEvents in the List coming back from the database match the date of the day element being rendered in my Calendar control like so (in this snip 'data' is List and results from a db query):
[code]....
Except r, my query result var, is always true no matter what data it receives. I have tried the sub query using other properties of tEventOption and get the same 'true' result each time. I know that the data does not reflect this result so I clearly have a problem with the structure of my query, but for the life of me I cannot find a way to resolve it.

In the first case, VS is telling me System.Web.Ui.MasterPage does not contain a definition for urrentUser. In the second case, VS says the type or namespace 'MasterNoNews' could not be found.

I've got a composite control (class) that exposes an asp:Label through a get-property. Is is possible to set the Text property of the Label through aspx-code?
I'd like to do something like this:
<cfw:MyCompositeControl runat="server" Label.Text="Test" />
One solution is adding each property to the composite class (like a public LabelText), but I'd like to set any property of any child control. So as new features of child controls become available, I'd like to be able to use them on my composite control. So basically I would like to set any property of the exposed child control.

I am writing a custom composite WebControl and want to expose styles of child controls it encapsulates to the ASP.NET designer. The code I currently have is similar to the skeleton below (which for simplicity only has one child control).
With the code below, I can see property "ChildPanelStyle" in the designer, but when I try to modify one of the properties (e.g. CssClass) in the designer, it immediately resets itself to its default value. It looks like the designer serialization isn't happening.
What am I doing wrong?
UPDATE
I've updated the sample with an additional style property that is managed directly by the custom control, rather than simply being the property of a child control.
The HeaderStyle property is persisted properly by the designer, but the ChildPanelStyle property isn't.
Of course I could manage all my styles like HeaderStyle, and apply them during rendering, but I'm hoping there's a simpler solution whereby child controls can take care of themselves, and I don't need any custom rendering.

I've got a custom ASP.Net web user control I've built; done this enough times before but this one is misbehaving and I can't spot why.
Where the calling page includes the user control directly in its markup, all is well and the control behaves as expected.
However if the page adds this particular control dynamically (to a placeholder in the master page, which is what's calling this whole thing) the elements within it stay firmly NULL - nothing from the user control gets written to the client at all, including static content within the user control.

I have a user control embedded in a web part. It has the following snippets of code:
[code]....
Why are some controls initialised and others not? How do I get around this if I'd like to update the Text property on currentPageLabel?
Update:
I've placed breakpoints all the way through the page life cycle and found that nextButton and currentPageLabel are never initialised. The breakpoints were placed at OnLoad, CreateChildControls, goButton_Click, OnPreRender, Render and OnUnload.

Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.
[code]....
As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.

I have a web application that uses the master/child page layout you get by default (at least in a VS2010 web project). The Masterpage has a NavigationMenu, each item on that NavigationMenu has a NavigateUrl that looks like "~/Pages/MyPage.aspx". This automatically opens 'MyPage' in the Content of the Masterpage, so that the master page with menu and header etc stays visible.
Now, the client has a guestbook on her old website (I'm basically rebuilding her website, adding the ability for her to upload new content in her browser), and she wants to keep it. This guestbook is from a 'free guestbook' third party website, over which I have no control. It's simply a website in the form [URL] .... which shows the guestbook for a user 'Username'.
In her old website, I was using frames, so the menu on the left side was in a different frame, and I would simply open the third party website in the center frame. That would create the illusion that the guestbook was on her site, while it was actually a completely different website in a separate frame.
In my new website I'm no longer using frames, but the master/child layout as explained. Is it still possible to 'host' or 'embed' this third party website as a 'child' of the master page?
I tried just putting the url to the guestbook in the NavigateUrl of a NavigationMenu item, but that doesn't work, it just navigates to the third party website and doesn't embed it in any way.

I have 5 dropdown lists that define a training class location and line of business: Site, Parent Client, Client, Program, Project I'm trying to build cascading dropdownlists that can work from any direction (i.e. select a site and all other lists are filtered by site...select a project and all other dropdown lists are filtered by project).

I have a webpage which does a lot of processing(for few minutes) and finally produces a result.
i have one more page which contains results of all previous operations.
Both pages are opened from a parent page. what i want is ,As soon as first page finishes its task , the result should be reflected in second webpage automatically.(Or we can say it should update the information according to the latest operation).So i need a page refresh at this instant. I don't want to do a regular interval refresh through Meta tag etc. Is it possible?

In my actions, I want to pre-load the User object and set some other properties, all BEFORE the action loads. I know there are events where I can do this, but how will these objects that I set be made available in my controller's actions once the filter fires and execution is now at the action level?
example:
public actionresult SomeAction()
{
string username = this.CurrentUser.username;

I am trying to come up with the best way to get only certain properties from a type using reflection. How can I differentiate the properties from each other?
I understand that I can use binding flags or name. But say I want only a certain four properties. Would the best way be to create a custom attribute for the ones I want then loop through all of the properties to see if they have that attribute?
