Hi, thunkers.
I have been searching on the forums for an answer to my question, but many of the possible solutions come with a thunkabe link that is expired, so I need to ask here:
I am working on a visual dictionary using Data Viewer list, but there are so many items that I have decided to use a first screen with List Viewer (simple List) to make it easier to locate the element that we need, that is to say, that the List Viewer works as a kind of DVL Index.
The problem is that I can’t find a way to make the List Viewer activate the Data Viewer list …
Is it possible? Any suggestion on how to solve this?
Thanks
You’re using Any Component blocks that require a component ID. This is a hidden value generated by Thunkable and is unique for each component. So the in list app variable RowObject get #i block needs a list of components, not a list of data source values as you have it.
One method is to use the row IDs as I demonstrate here: Conditional Formatting of a Data Viewer List (aka "Painting the DVL").
Another is to use the all Data Viewers block from the Any Component drawer and then get #i of that list. That will provide component IDs.
Hi, Tatiang. Thanks for the reply.
I had already seen your approach to “painting the DVL”. I´m working on my own custom layout
Do you mean I have to create a variable and write something like this to have the ID?
And when you say
“Another is to use the
all Data Viewers block from the Any Component drawer and then get
#i of that list. That will provide component IDs.”
Are you meaning this?
Where should I use it? I´m a bit obfuscated, really.
Yes and yes! I like the latter method. So you replace this:
with this:
I´m trying the latter method, applying it to all of the elements of the DVL
but the web server doesn´t seem to work very well today. Any way, I only get a white screen. Is there any other thing I should change?
A white screen usually means that you’re trying to get a property name that doesn’t exist. Start simple and get one line of blocks working before you attempt to make all of them work at once. I have a method I use for debugging Thunkable projects. The link is below.

I cant find the blocks for debugging
Did you watch the video I linked to? There are no debugging blocks. There is a method I use for debugging.
No. You had the blocks correct before:
You just need to figure out why it’s crashing.
Hi Tatiang.
Yes, I have seen your video, but I can’t find the blocks you use. I have been working in STP, and it generated a blank screen. I have switched to D&D, and it no longer generates it, but whatever choice I make in the Simple List, it always takes me to the same page 1 with the bee.
This is my DVL
And these are my blocks lately:
But unfortunately it´s not working for me.
You don’t need to use cloud variables. When using a data source, it will be stored inside the app. Therefore, you can do something simpler. Just grab the “call data_viewer_list#” and set the row id to whatever you need. I am creating a password manager app, and therefore need to use data sources.

Hi, Ksampei. I’ve just read that you have a way to solve this problem. That’s great. If you want a private conversation, my email is similar2similar@gmail.com
