Questions related to ADO.NET EF and one unrelated

Hi Imar,

I have 2 little questions, i wanted your opinion on the first question and the second is related to GridView display.

1- In which scenarios it is better to use ADO.NET Entities Framework or SQL to LINK ? It is okay to use ADO.NET EF for a simple website too ?

2- It is normal that the asp gridview render as a floating element ? (Such when i add a <p>test</p> on the line after the gridview end tag it still write test at the right of the grid. Is there an explanation to this ?

Thanks a lots.

1) Yes, you could. Whatever you feel more comortable with. EF can be just more complex.

2) It doesn't do that by default, so there must be something in your page and CSS that causes this to happen.

Cheers,

Imar

What you mean by "EF can be just more complex." ? Actually the only tasks i need to do is using EF with LINQ in order to perform CRUD operation in my table.. such as your book showed.

Thanks for your fast answer!

It's a broader, more powerful and thus more complex technology. For example, it supports many to many relationships, and has a slightly different API than Linq to SQL has.

AFAIK, yes, the Pro 4 book discusses EF, but I don't know to what extent. You may also want to look at the Entity Framework book by Julie Lerman. There's a second version coming out soon.

Alright, i will stay with EF and probably learn more about it.

Thanks Imar.
