I've create a custom attribute for my web pages... In the base page class I've created I'm trying to pull if that attribute has been set. Unfortunately it does not come back as part of the GetCustomAttributes function. Only if I explicitly use the typeof(myclass) to create the class. I have a feeling it's due to how asp.net classes are generated.
[Code]....
Is it possible to access a parent class from within an attribute.
For example I would like to create a DropDownListAttribute which can be applied to a property of a viewmodel class in MVC and then create a drop down list from an editor template. I am following a similar line as Kazi Manzur Rashid here.
He adds the collection of categories into viewdata and retrieves them using the key supplied to the attribute.
I would like to do something like the below,
public ExampleDropDownViewModel {
public IEnumerable<SelectListItem> Categories {get;set;}
[DropDownList("Categories")]
public int CategoryID { get;set; }
}
The attribute takes the name of the property containing the collection to bind to. I can't figure out how to access a property on the parent class of the attribute. Does anyone know how to do this?
I have an existing class for an input, is it possible to add an additional class for the object in C#.net, instead of doing a if/else and not having a preset class on the object in the first place?

What is the class attribute and how to use
View 1 RepliesI just download XAMPP, and it is running in my local computer. I added the index pages, and it works fine. However, when I copied my pages and all related information,I tried to access the page. Then, it displayed the error message below.

I have an interesting problem with a WCF Service I am creating. As background fodder my solultion uses MVC 3 RC2 as the web interface. I am developing the solution as an N-Tier application using the Entity Framework 4.0 with POCO Self Tracking Entities, repository and unit of work approach. I am using the STE's more as an advanced POCO since STE do not seem to play well as of yet in the real world as they were meant to and since they do seem to give me better interfacing with the DB through my layers still. Additionally, I am incorporating WCF into the solution as the backend for the models based on info I am reading and the fact that I will need to also access these services via a windows service app on the client computers.
So, I have a datastore which includes my edm and the repositories. The POCO STEs are generated in a separate layer in what I have called my Domain Models. Within my domain area I also have a Core app holding my utilities. I am currently incorporating an additional domain element as a WCF service using the RESTful template. This WCF will be servicing both my MVC controllers and a Windows Service app on the client computers.
Now, on to the problem: Within this solution I have an Entity Set of People (or Person?). Within that Entity set I have a chain of inherited entities as follows Person->User->StaffMember->Provider where Provider is the resultant child. Within my WCF I have a ProviderService, a StaffMemberService and a UserService. In each of these Services one of my OperationContracts is a Get(string id) amongst others. the Get(String id) contract is the one that is causing me problems. Within that Get(String id) contract I do the following for the User:
[Code]....
and for the Provider:
[Code]....
Now, what has gotten me completely confused is that the Provider one works like a charm. But if I use the UserService to call the User of the same Id (Since User is a base class for Provider, this should work) I get an error saying it was a bad service call. (The ProviderService, as stated works and returns all the correct data). When I debug it, the UserService Get(String id) function actually works as expected up to and through the return statement (ie the user variable actually contains all the proper data that I would expect on the call). It is only after the return that I get the web page giving me that error and points me to the help page for the service. (I am using the browser to view the results at this point only). </P><P>I am assuming it has something to do with serialization? But why is it displaying the derived class with all expected data, which yes does include the data not being displayed as a user data, I am calling the data using the same UserId. I am not expecting someone to inspect my code, but to be a traffic cop and point me in the direction I need to look.
I have a vb class that reads a single row of data from an SQL view. I want to add a property to it that will expose the value of a new bit field. But whatever I do my class always returns the value "false".What am I doing wrong?
Public ReadOnly Property IsPublished() As Boolean
Get
Return valPublished
End Get
End Property
Here's the relevant line from my datareader: Me.valPublished = Convert.ToBoolean(theObjectReader("Authorised"))Authorised is my bit field. I have tried it with and without the "ConvertToBoolean" statement.When I response write the value of the property for rows where this field is true, it always shows false.
I have a vb.net application which I'm trying to run in VS 2008. The application builds successfully, however, when I try to debug the windows application it throws the following error, "Retrieving the COM class factory for component with CLSID {794D671E-F0F0-11D2-BEB0-009027438003} failed due to the following error: 80040154." I've been searching for a solution for a few days now with no luck. I've tried to register the referenced DLLs (w/regasm command), messed around with the configuration manager, etc. Also, please note that the application ran successfully in Windows XP, but it no longer seems to work since I've upgraded my OS to Windows 7 (I've tried to run the application in x64 and x84 platforms w/no luck). Also, I'm referencing the following DLLs:
INTEROP.ASPEMAILIB.DLLINTEROP.SCRIPTING.DLLINTEROPS.MSXML2.DLL
Is it possible that some of these DLLs aren't supported in Windows 7?

View 1 RepliesIn my Code Behind I use several times this code below to bind and rebind (for refresh) e GridView after an insertion or other operations completed using EF objects.
Using a simple gridview.DataBind(); does not work because I call EF programmatically so I thought to use a Class to keep in memory this code that can create Objects for my GridView and call it how many time I need in my code avoiding redundancy.
IEnumerable<CmsContent> queryContents = myCurrentSlot.CmsContents.Where(x => x.IsPublished == true);
uxManageContents.DataSource = queryContents;
uxManageContents.DataBind();
Or do you know a batter way to Refresh the gridview after EF executing some commands? how to do it?
remember that I do use any data source web control for the gridview but i bind it programmatically.

I'd like to inherit all my controllers from a custom base class that I write myself. I can change the line every time I add a new controller, but it would be nicer if I could somewhere specify the default value that gets set there. That way I wouldn't need to worry about forgetting this, and other people who get added to the project later on would have an easier time.

I have a VS 2003 Web app that I'm creating. I'm using a Panel control and I'm trying to apply a CSS class to this panel. However, when I try coding the following statement

I'm building an n-tier application, with the web client and the class library separate. I'm also using the factory pattern of development, using interfaces to act as containers for different objects they are associated with. The problem I'm expreriencing is that I declared a public interface class in the class library and I can create an instance of it in in my aspx pages but whenever I declare it in my custom control code-side, i get an error, like so:
Error 20 The type or namespace name 'IContentMaker' could not be found (are you missing a using directive or an assembly reference?)
notge that I have inherited the class library namespace using the 'using' keyword just in case you are wondering. My code is like so:
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using TQO_Classes ; //importing the class library project
public partial class PageContentMgr : System.Web.UI.UserControl
{
private IContentMaker _data; //this line throws the error, it works fine on aspx pages

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I have created my own custom role provider class "SGI_RoleProvider" and configured properly.
Everything is working fine.
Suppose that I have added a public method say "SayHello()", then how can i call that. Because if i am using Roles then the method is not displayed. If i am forcefully using that Roles.SayHello() then compiler gives the error.
how can i call this. Because creating a new instance of SGI_RoleProvider is meaningless.
I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.

As you can see the class has the ScriptService attribute and the methods have the ServiceMethod attribute.
