Dear Sir,

I have Teacher class and Student class, both of them have Id/Name/Age properties. Student has a property named TeacherId.
I show a list of teachers in a RadGridView and use another RadGridview as its child table. My question is - how to merge these two grid views' columns, make them look like a single grid view. (Please see attachment.)

NOTE: Because I must retrieve data from web service when I click the "+" to expand a Teacher row, so, I cannot use RadTreeListView.

Thanks and Regards,
Tim

Hi,

 You can still use RadTreeListView no matter how the data are retrieved however you will need to use MVVM instead control events, etc. If you create your own model similar to this blog post RadTreeListView will not know that your data are retrieved on demand using service.
