[How Do I:] LINQ to SQL: LinqDataSource

Great video Scott! You make some of the best videos. You are quick to the point, but not too quick.

Sweet video, almost a new way of querying the datasource without having to write one.

I tried to follow the steps of your video and I'm getting

"Operator '==' incompatible with operand types 'Int32' and 'Object' " when I try to view thw web page.

why?

Hi Scott,

Thankyou

uthai, you probably need to add a reference from the website project. In the solution explorer, right click the website project node, choose "Add reference..." and select the System.Data.Linq.

Many thanks for the great videos

VB Please!!!!

I don't get something...  I was trying to do the <%# Eval("Category.CategoryName")%> stuff in the ItemTemplate, but it wasn't working.  It showed "Databound" in the designer view ok, but in the browser, the field was empty.  

But then I went to The GridView arrow menu, under "Configure Data Source...", Next>, Advanced..., and I had to check "Enable the LinqDataSource to perform automatic updates".  Then the fields started showing up correctly.  Why is that?  

I can Eval other direct properties of the Product, like "CategoryID", but no foreign key lookups (i.e.: something of the form "Category.xxx" )

Why doesn't the automatic JOIN, through Category.Category name seem to work if I disable the LinqDataSource auto updates?

What's going on?

how to ADD NEW RECORDS as this wonderful video described select/edit/delete operations but not about ADDING NEW RECORD

kindly tell that way as well or some link ...

thanks

Thanks !Jërëjëf!

Just wish to say that it was simply great

I have tried to add the Linq data C# class but i haven't been able to successfully accomplish that because there isn't a Linq data C# class just the normal C# class and i have tried those too but they dont give me the ability to add the data mapping file to the class. Please explain to me how i could accomplish this task. Thanks.

Simply Superb..

thanks your video
