I am trying to display sorted data using the Data List Viewer. I want to use the data list viewer to show the data rather than using List Viewer because I want to be able to take advantage of the display options and swipe features in the data list viewer.
I have a bunch of values stored as a list in a variable. I want to write that list into a column in a Data Source table so that it can be displayed in the data list viewer. However, I do not see how to do this. Where do I find out what the rowID is for the cells in the Data Source? Is there a way to write the data in the list to a row using a loop?
As I understand it, you can only write data into a cell using the block that requires a click event. I want to write a list of data into a data source column but this does not seem to be possible.
Of course it is possible. If you can explain your requirements in more details and/or provide screenshot of your blocks you will find many in the community who can help you achieve what you want.
I have a list stored in a variable. The list has been sorted according to a user preference. At the moment, that list is displayed using the List Viewer. However, it would be much better if I could transfer the list in that variable into a column in a Data Source so I could display it using the Data Viewer. My question is what blocks do I use to transfer the list from the variable into the Data Source. When I look at the Data Source blocks I do not see a way of doing it. If there is a way to do this, it would be great if you could explain or point me in the right direction. Thanks!
You will need to create a data source and have the user preferences in this data source. You can then use a block in the data source drawer called [List of values] to get all the data available in the data source. You can then assign a list variable the values in the data source.
I think this doing the inverse steps that I want to do. I want the app to sort a list into a variable and then transfer that list into a column in the Data Source. The list will keep changing and so the data source would need to be updated constantly. What I think you are describing is entering data into the data source first and then calling that data using a variable?
The only data block I can see where you can write data to the Data Source (rather than creating the data in a separate table beforehand) is the ‘Set Cell’ block, but that only seems to fire when there is a click event.
The reason for asking about this is to use Data Viewer instead of List Viewer to show certain data in a list. At the moment, the List Viewer shows my list variable nicely. However, it would be much better in terms of functionality if I could have the Data Viewer view the list so that the user can then swipe left/right to perform other functions. As far as I can tell, there is no way to swipe left/right on a list viewer item.
I apologize for the misunderstanding.
I’m out now but when I go back to my computer, I’ll send you the blocks that should perform what you just described.
@slothball
I assumed you already have your choices in a list so you need to loop through the list to add the the contents of the list to the Local Data Source.
You might also need to use [Delete All Rows] block to clear the Local Data Source when needed.
