    <p>I have a main 'Products' table and a 'Products_Recommended' table. I want the users to be able to select several products from a GridView using checkboxes and then insert those Product IDs (prodid) into the Products_Recommended table in such a way that a main Product ID is entered (coming from query string) and potentially several recommended ProdIDs get entered. So far so good. But I need to be able to show the checkboxes to be checked if there were already prodids in the Products_Recommended table previously. The code below show a 'sqldatasource1' which gets the data from the Products_Recommended table based on query string. I just don't know how the checkboxes can get checked because the GridView has a different sqldatasource binding it. Thanks!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
