Android Question AS Wheel Picker: control reset

Aldo's · Apr 3, 2025

I have been using this fantastic @Alexander Stolte control with satisfaction for a long time.
I load a picker from db loading everything on an array.
Now I have to empty the picker, load the array again and re-run the data loading in the picker.
But I can't find a way to clean the picker. I saw that there is a function picker.Clear(col), but putting the reference to the column does not do anything.
Where am I going wrong?

As I understand it, you want to remove all columns and add new columns?
You can remove all columns with the following code:

B4X:

    For i = ASWheelPicker1.NumberOfColumns To 0 Step -1
        ASWheelPicker1.RemoveColumn(i)
    Next

The “ASWheelPicker1.Clear(0)” function clears the list at the specified column, but does not remove the column.
In my test I saw that the list is emptied, if this is not visible for you, simply make a “.Refresh”, but this is not needed because these changes are made directly.
