I am using a combination of GridScreen and VideoScreen examples from the SDK. My goal is to make a GridScreen populated from XML which is hosted on my server. I am populating the List Names properly, but cannot figure out for the life of me how to populate the list of content in the rowIndex (setContentList function). Here are all the relevant code snippets I am using:

XML - EDIT: READ BELOW POST TO SEE SOLUTION!!!
(for now just using a very slightly modified sample feed XML from the SDK. Once I have this working I will make custom XML with my own content)

Relevant part of my appGridScreen.brs. Once again, I am getting the List Names, but cannot populate the contents.

Function showGridScreen(screen As Object, gridstyle as string) As string

    print "enter showGridScreen"
    
    conn = InitCategoryFeedConnection()

    m.Categories = conn.LoadCategoryFeed(conn)
    m.CategoryNames = conn.GetCategoryNames(m.Categories)

    categoryList = conn.GetCategoryNames(m.Categories)

    screen.setupLists(categoryList.count())
    screen.SetListNames(categoryList)

    initCategoryList()

    for i = 0 to categoryList.count()-1
        screen.SetContentList(i, getShowsForCategoryItem(m.CategoryNames))
    end for
    screen.Show()

The problem part is the last for loop. I am just not sure what the heck to pass to the getShowsForCategoryItem function, which currently looks like this:

Function getShowsForCategoryItem(category As Object) As Object

    print "getting shows for category "; category
    
    conn = InitShowFeedConnection(category.kids)
    showList = conn.LoadShowFeed(conn)
    
    return showList
    
End Function

So if you have a suggestion of how to populate the ListNames with the appropriate content, please let me know!
Thanks.

So this took me almost a day to figure out but I finally got it. Here's the solution just in case someone sees this thread in the future!

The issue was that I needed to remove categoryLeafs from the example videoplayer. There is quite a bit of code you have to change to do this properly, so I followed the step-by-step tutorial here:

viewtopic.php?f=34&t=57936

The for loop in showGridScreen ends up looking like this:

for i = 0 to categoryList.count()-1
        m.curCategory = i
        screen.SetContentList(i, getShowsForCategoryItem(m.Categories.kids[i]))
    end for
    screen.Show()

...

and here is getShowsForCategoryItem:

Function getShowsForCategoryItem(category As Object) As Object

    print "getting shows for category "; category
    
    conn = InitShowFeedConnection(category)
    showList = conn.LoadShowFeed(conn)
    
    return showList
    
End Function

hello Matt604,
Did this code actually work for you?. I am still fighting with it. Can you please post the entire mod. code. This may help us solving the puzzle. Thanks.
