update radgrid with radiobuttons

[David Gunderson]

What I have is a grid that I am loading questions with a asp radiobutton with a go or a no\go.  I have a set of questions and then some question might have sub questions that i load into the grid.  a nested radgrid with the main question and sub questions.  What I need to happen if a sub question radio button is picked as a no\go I need the main question button to automatically be changed to a no\go as well.  Is this possible with a nested grid.  Here is an example of my radgrid.  I also need to save all of them to a table with the question answer on a asp submit button, how do you itterate through the main and then sub tables to save the information.


<table width="100%">

Hello David,

Please refer to the following help article explaining how to iterate items in hierarchy. You can also access the parent row from the child item like that: item.OwnerTableView.ParentItem. Then you access the radiobutton in the cell as described here.

Best wishes,
