I am developing a 2 level hierarchy radgrid.
The Parent grid is populated by importing a csv file's data.
The child grid is supposed to be populated by custom function i call from code behind.
The issue is that the detailtables is not displaying any data although in "e.DetailTableView.DataSource = dtF;" dtF (datatable) have the relevant data.
importcsv.png shows the data that binds to the parent grid.
subject.png shows the detailsbind event.
dtF.png shows the data that need to be bound to child grid.
ui.png is the parent grid that is successfully bound. But on clicking the expand button, child table is not getting displayed although the datasource contains the data.
