Multiple DetailKeyField MasterKeyField

[Nikhil]

Hello

I want to know how can I implement Multiple DetailKeyField  MasterKeyField b/w parent and detail table view.  I am developing 5 level grid and want to show data on detail table from parent table, hotel_booking_id and seqnum column in detail view table.

Thanks

Hello Nikhil,

RadGrid's ParentTableRelation property does support multiple master/detail keys, you just need to specify a separate GridRelationFields collection for each. For example:

<ParentTableRelation>
    <telerik:GridRelationFields DetailKeyField="hotel_booking_id" MasterKeyField="hotel_booking_id" />
    <telerik:GridRelationFields DetailKeyField="seqnum" MasterKeyField="seqnum" />
</ParentTableRelation>

More information you can find at the following help topic:

Hope it helps.

Hello Nikhil,

In this case you will have to manually bind the detail tables using the DetailDataBind event of the RadGrid control. In the event handler you can access any parent level through e.Item.OwnerTableView.ParentItem property and extract the necessary parent data keys. More information you can find at the following online example and the related help topics:
