Persisting values in hierarchy when inserting

[Vlad]

Hi.

I have a table with a subtable.

The subtable has these fields from main table -
                    <ParentTableRelation>
                        <telerik:GridRelationFields DetailKeyField="SongID" MasterKeyField="SongID" />
                    </ParentTableRelation>

These work great for just showing a list but when I try to Add a new item then SongID becomes nothin but I want it to be the same value as when I see the list.
How can I accomplish that? I need that SongID for my datasource and I want it to be populated even when I do "add a new entry". It just should equal to the main tables SongID.

Thanks

Hi Vlad,

Go through the online demo given below.

I forgot to mention that my objectdatasources return objects so there are no InputParameters of any sort. How do I deal with that?

It did work with parameters but now we converted everything to objects so instead of passing a bunch of parameters we just define DataObjectTypeName.

Thanks
