json = ParseJson(ReadAsciifile("pkg:/dir/file.json"))

   for i = 0 to json.Count()-1

      print i,"Description is ";json[i].description
   end for
end if

it gives me an error it doesnt compile

[youssefsherif]

json = ParseJson(ReadAsciifile("pkg:/assets/Data.json"))

' check json:

if json <> invalid then

print json.Count(); "entries"

for i = 0 to json.Count() - 1

print i, "Title is " json[i].title

print i, "poster is " json[i].poster

print i, "desc is " json[i].description

end for

end if

this is what i did but this only displays the data on the terminal, i actually want to use the data to set them for the fields i already have and display on screen

[youssefsherif]

instead of doing m.tile.title = "title1"

and m.tile.descriptionText="this is new description for first tile"

i want to load it from the json file

I don't understand why use a json with multiple content and get only 1, you should use a rowlist and select the one I want to display information from

[youssefsherif]

i want to retrieve all data in the json file but i was just trying on one i dont know how to do that 

[xoceunder]

Could you help to know more about the code so I can help you?

[youssefsherif]

okay so what i want to do is that instead of setting the fields {title and image and description} manually from here like the code below i want to load them from the json file.

so instead of doing this:

m.tile.titleText = "Title1"

m.tile.descriptionText = "this is the new description for the first tile"

m.tile.posterUrl = "pkg:/assets/images/image1.jpg"

i want to use the data in the json file

@youssefsherif, when you post code don't do a screenshot, do a copy and paste into a code block.  The icon looks like </> when you expand the toolbar when you make a post.  It will open a popup for you to paste your code into.

Just replace the text in the code with the proper object property from the parsed JSON.

Instead of:

m.tile.descriptionText = "This is a description"

You would have:

m.tile.descriptionText = json[2].description

json[2] is third entry of json and is an object with several parts:   title, poster, and description.  Just "json" is an even larger object (an roArray) with, in this case, 3 entries each of which is an object itself (an roAssociativeArray).  Array indices start from 0, so in this example json[3] doesn't exist.  There's only json[0], json[1], and json[2].  You need to understand these concepts or you're going to have a tough time with BrightScript.
