I want to search in DataSources and get the column ID

[tatiang]

You can use an integer for the row id, corresponding to the row number (2 for the second row, 5 for the 5th row, etc.). Or if you really need the row ID, you can get it from the list of values block. See this post:

List Data Viewer List Row ID for Airtable

I didn’t quite understand the problem about the background but to get all the rowID of your Airtable table you need to use the following block in the screen start or open event. [list_of_values] Creat a variable and assign it first as empty list then in the open or start event of your screen assign the block [List of Values] to the variable. Remember to change [column 1] in the image to “ID”. This will give you a list of rowIDs of the table you want.
