I,am trying to create a self association relation for an organization chart data tree in Entity Framework,after trying different ways for prevention of exceptions like 3007 and etc. I found that when I put my foreign key in my POCO near Parent and Items navigation properties its work.but I think this is not correct that we have both ParentID scalar property and Parent navigation property. review this and tell me is it correct or not.I'm using VS 2010 RC and ofcource .net framework 4.0 RC

I keep getting the following error message when i try to save a poco entity, using Entity Framework as the OR/M :-
Entities in 'SqlServerContext.Foos' participate in the 'FK_Foos_Bahs' relationship. 0 related 'Bah' were found. 1 'Bah' is expected.
the error message makes sense -- but that is NOT what I modeled :( (or am trying to model). It's saying that if I wish to save a Foo, then I need 1 instance of a Bah. A Foo can exist without a Bah. The relationship should be 1 <-> 0-or-1 .. not 1 <-> 1.
If I use the extenders (for example mask edit) in place of some of the built in validators such as RegularExpressionValidator for exampe, will Page.Validate() still be called automatically and perform server side validation using the extenders?

I have 3 tables: People, Fruits and a table named People_Fruit which connects People to Fruit tables. in table People_Fruit we enter records which determine who loves which fruit. People_Fruit is at "Many" side of both People and Fruits table. at this link you see this in a WinForms project: [URL]
I want to show people in a ASP grid. when the user click on a person's record he sees all record of fruits table regardless of whether the person loves it or not. there is a CheckBox column which its value determines if the person loves the fruit or not. user can check or uncheck the checkbox. If user checks the checlbox PersonId and FruitID must be entered to the People_Fruit table and if the user uncheck the checkbox the correspond record must be deleted.

I have written some vb code that inserts whatever has been written on my page into an Access database. Only problem is VWD throws up an error saying that the syntax of my SQL statement is wrong. I am 95% sure that this statement is correct because when I saw the statement in Text Visualizer and tried that statement in MYSQL the data went in perfectly.
I have pasted the code below:
strSQL = "INSERT INTO User (UserID, FirstName, LastName, Password) VALUES "

View 4 RepliesI have a website which displays news information. It displays the titles at the default (home) page and when click it shows the full story.
I use object datasource to load the news titles.
Now, sometimes the database server lose its connection or changes to the database and it affects the whole website because error is reported at the Application level. I would like the Home page to still show but the section where the news titles usually appears will now show an error message that the database is down (Refer below my part of my code).
How can I achieve that?? I tried to do that at the page_error level but it displays nothing. I don't want to pass the error to application level, I want to handle at datasource load/binding level so that it display this error message at the news section and other home website information can still be shown.
