get data from gridview in HierarchyChildTemplate

[Sam Ur]

Hi,
I have created a RadGridView with HierarchyChildTemplate, this template contains DataTemplate which contains RadGridView.
I was wondering how can i get to this RadGridView (inside my template) from code, because I would like to get all selected items in this RadGridView.

Well I don't know, what i want is the followning scenario:
 I have already loaded data Hierarchicly - now i have like categories and when i expand them (one, two, etc.) i have a radgridview with subcategories which i load using RadGridView.HierarchyChildTemplate.
Now I can select this subcategories and as a final result i would like to get selected subcategories for every category.

I thought i might solve this by looping through all my main items (categories) and then for each category (item in my "main grid") i would sort of get (do not know how) - a radgridview with selected items.

So if i have something like....

[+] Category one -- i expand this row in my grid i see my sub categories ....
    [ check ] Sub Category 1
    [ check ] Sub Category 2
    [ ] Sub Category 3    
    [ ] Sub Category 4

Now if i select only Sub Category 1 and Sub Category 2 ... i would somehow like tho get only this items (?)

Maybe I should use different approach.
Maybe I should use a hook on selection change and monitor items aded or items removed values and based on that fill my list of selected subcategories (?)

Thnx for your help.

Solved my issue...basically I helped myself with Selection changed event...and then used 
...
var senderElement = e.OriginalSource as FrameworkElement;
var rowType = ((RadGridView) senderElement).SelectedItem.GetType();
...
and based on this implemented my logic :-)
