Hi Friends,
I am using the Telerik RadGridView. I need to show a list of master records and on expansion I need to show the detail of child records. Do you have any such sample. What will be the class structures with MVVM approach.
Right now I have a - GridViewModel - that has an ObservableCollection of GridRowViewModels (master records). GridRowViewModels is set to the ItemsSource property of the Gridview.
Now on expansion, I need to display an ObservableCollection that I am exposing through GridRowViewModel in the expanded section.
Please help.

Hello Andy,
I attach a sample project that suggests a possible approach for using MVVM and how you can set the RowDetailsTemplate property of the GridView.
For more information you can check:
- our Row Details documentation section.
- our Hierarchical GridView documentation section.
- our demos for WPF / Silverlight (some are in the Hierarchy section).
- our SDK examples.
I hope this helps.

Hello Boris,
Found your sample very informative and it helps explain how to use the GridView. On the Telerik Demo application it has a topic "Grid View | Exporting to Xlsx and PDF" that will address a coming project. I tried to merge its sample code with yours but it breaks your code. Is there way to you can guide me to add the "export" with excel grouping to your code to test and understand the operation?
