I'm new to the RadGridView and I want to implement rowdetails in my RadGridView. To help performance, I only want to load the data in the rowdetails when I expand it and make it visible.  When the rowdetails is visible, it will get data from the database based on the ID of the parent record.  In the rowdetails, I also have another GridView which will be populated when the rowdetails is expanded.  I'd appreciate it if someone can point me in the right direction.

Thanks.

Hi,

You caould use the Row Details events to lazy-load your data when the user expands them for the first time (using the LoadingRowDetails event).

You can do anything in those events and populate your grid from anywhere.

I hope this helps.

Kind regards,

Thanks Didie.  I've know how to populate data in the details view using the same data context as the parent row but now I'm interested to know how to populate the details view from a separate datasource.  I'm probably getting ahead of myself here as I'm also new to Silverlight in general.  Do you have any tips?

Thanks

Hi,

 You can find your details element like described here. Once you have found it, you can pull the data from the separate datasource and assign it as an ItemsSource for the child element.
