master/detail using code behind sample

[Henry]

I am trying to build master detail grid. This is the sample I checked: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/selectedvalue/defaultcs.aspx 

I am not using sqlserver and would need to do the bindings in the c# code behind, is there any sample/demo for this? say I need to get the select row from the master grid, get the detail records for that row and bind to the detail grid. 

Thanks.
