Can you explain how to use this reference type to overcome this error
I seem to be having issues with posting forms with DropDownLists. I've looked all over the net and tried various solutions, but none seem to work for me.
I'm getting the following error: The parameter conversion from type 'System.String' to type 'Models.Organization' failed because no type converter can convert between these types.
Here's my ViewModel:
[Code]....
Here's my controller:
[Code]....
The objects are generated by ADO.NET Entity Framework. Organizations is its own object, but also a property of Profile (each user belongs to one organization). Now I understand what the error message is saying, just not sure how else I'm supposed to do this.

I just copied the website files to hosting server. I dont have any bin folder in my website containing dll files.. i googled this error, results are showing that, the website should be compiled and bin folder should be in correct place.
I can not figure out what the problem is with my programming. There is no problem working locally, but uploading and making live is where this problem occures.
I have created a web application project in vs2005. This is a simple website which has one form and a master page. It runs fine in my local machine but when I publish it to my hosting server it shows error in master page i.e.Parser Error Message: Could not load type 'WebApplication1.Site1'.

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 i.id 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.
I have an ASP.NET 3.5 website application using C# and SQL 2005 running on a web server. Now the application has the ability to create new aspx pages with content and the relative aspx.cs and design.cs pages needed on the fly and store them in the base directory on the server. Think of it as a crued Visual Studio website on the server for admin to click a few options on a page then the new pages are created for them without the need of a web developer. This all works fine and the code is working 100% (for the moment).
My problem now is the following: When i now navigate to this newly created page i get the following error - Parse Error : Could not load type 'Namespace.PageName'
I've looked into the reasoning and microsoft say "These errors occur if the .aspx page contains a reference to a code-behind module and if the application has not been built." Which now makes sense the application does not realise that these new pages are part of its system even though i can navigate to them.How do i get the system to recognise these new pages and rebuild itself accordingly?Now i cannot rebuild the system localy then reupload to the server, this needs to be accomplished on the server by the system, because the site cannot afford to have down time everytime admin decide to add new pages.
I am developing the Windows Live@edu SSO integration with asp.net custom code.It uses the DLL called "System.Management.Automation" for executing Windows powershell v2.0 commands for connecting Outlook Live Apps.It works fine in localhost,but during deployment in Windows server 2008 , it shows error called
Could not load type 'System.Management.Automation.Runspaces.PSSession' from assembly 'System.Management.Automation, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'."
