[Solved] Update localdb from web API data when screen opens

[thinkkable]

is it possible to do this.

i have an array like this

and I want it when the screen opens, then update cells for each array of web api. like this.

I want my application to run offline without an internet connection. By first saving the object in localdb. How can I achieve this workflow. Thanks

Hi,

Does this help you?

Thanks!

I do not really understand it, what you need of LocalDB, if you already have a data set? What of upload LocalDB, if you open the screen, these data already exist in a variable?

I want to make an offline listview. therefore I save all objects in localdb. I have not tried it, but thank you @kartik14 . because thunkable listview cannot be custom and appears only list without image. I tried other ways. Do you have any advice? @actech

[actech]

You do not need to use LocalDB to add data to ListViewer. All data record in the List, and then copy them to the List Viewer.

I’m trying your way @actech

Can this be used to api call so that my list becomes dynamic?

[actech]

Yes. You need to instead of my data in the variable List insert your data, obtained from the API in JSON format.

thanks @actech I will try your way

@actech how to create variable “start”

I did not find you using initialize “start”

[actech]

These blocks are created from the function block parameters

.
