The null value cannot be assigned to a member with type System.Int32 which is a non-nullable value t

When i'm trying to update a table using dynamic data, i'm getting the following error. I was trying to google the solution for the whole day, but it didnt work. I tried to declare the type of parameters like this

<asp:LinqDataSource ID="DetailsDataSource" runat="server" EnableUpdate="true"
                OnInserting="DetailsDataSource_Inserting"
                onselected="DetailsDataSource_Selected"
                onupdating="DetailsDataSource_Updating" > <UpdateParameters><asp:Parameter Name="PK_ID" Type="Int32" /><asp:Parameter Name="id" Type="Int32" />
                <asp:Parameter Name="c_titulu" Type="Int32" />
                <asp:Parameter Name="perio" Type="Int32" />
            

Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help. 

Hi,

This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
        {
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
        }

Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

On web.config I already have this:
<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?

Thanks.

The next version of SQL Server, code-named "Yukon," will offer enhanced support for user-defined types (UDTs). Because UDTs can be managed by the CLR, you can represent a wide variety of data structures to create types not possible with previous versions of SQL Server. With UDTs you can more precisely control the kind of data your type accepts, resulting in better data management. This article explores UDTs in "Yukon" and covers their design and implementation.

Hello,
 Why am I getting this error on line:

               sp.Price = Convert.ToDecimal(collection.GetValue("Price"));

sp is :
  SPecials_Templates sp = new SPecials_Templates();

SPecials_Templates Defined:

    [MetadataType(typeof(SPecials_TemplatesMetaData))]
