Problem associating linq view with table

Hi EE,

I have a listview that is bound to my Products table.  Within this listview I have dropdownlists that are bound to a view.
The reason I am using a view is because I need to display 2 fields from different tables.
The primary key for the view is a key in the Products Table.
I keep receiving an error, saying... Message: DataBinding: 'Service2020.ProductsLU' does not contain a property with the name 'vBrandsTypes'.
I assume it is coming from...
 <asp:Label ID="lblProdcat" runat="server" Text='<%# Eval("vBrandsTypes.ProductType") %>' />

I tried dragging the view onto the table in the dataclass designer, but it did not work.
What can I do to get this to work?

Thanks

To your statement, "I tried dragging the view onto the table in the dataclass designer, but it did not work.", a view is like a table so when you drag it on to the Linq to SQL design surface drag it to an empty area and NOT on top of another table.

Yes, I know that.  I just thought I read somewhere that I could associate a view with table by doing that.
How can I get my view to link with the table?

Thanks

Hi Sheritlw;

Sorry I misunderstood you. Here is how you can do this.

1. In the design make sure you have your Products table and the View.
2. In the OR/M designer, drag an Association from the toolbox and click on the Primary key field
    in the Products table then click the field in the View that the primary associates with.
3. In the View click on the field which is to be the primary key which was selected in step 2 above.
4. Now open the Properties window and change the property "Primary Key" from False to True.
5. Save and compile, you should be good to go.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Hi Fernando,

I tried what you said, except for step # 4 (didn't have primary key option) and I still get the same error.
'Service2020.ProductsLU' does not contain a property with the name 'vBrandsTypes'.
The primary key would be in the View (vBrandsTypes) and the foreign key in the ProductsLU table.
I've attached a picture of how I did it.
Thanks so much for your help.

Hi Sheritlw;

I took the same steps I put in the procedure above and the image below shows the results.

OR/M of Northwind DB with Table & View
Also please not the direction of the association. If it is still not working what version of Visual Studio are you using?

Pleas note that the Properties panel has a Primary Key property and is set to True.

Hi Fernando.

THANK YOU... It works GREAT!  
I didn't select the id to see it's properties, that is why I didn't see Primary Key.

You are great...
Thanks again.
