I can use the selection function to find the number of the clicked list.
The selected list changes to the specified color.
I want to specify a selection value in the source so that the list appears to be selected.
However, select a value to the list selection does not change the display.
You have to use the Selection Index block. That block accepts a number.
this will only set selection index to +1 will not show any effect , what do you want to do actually?
When I specify a selection Index in the source, the select item will be highlight
I changed the Selection index, but nothing happens on the screen.
AFAIK, you cannot do this programmatically, a user has to physically select an item in the listview to highlight it.
Thank you for your reply.
How can i implement it in other ways?
Here is one way:
You may find an extension that can also do it?
Buttons are also a good idea.
The program has no right answer
However, my program is difficult to implement with a button because the number of variables in the list varies from 1 to 200.
I looked for an extension, but I haven’t found it yet.
Use dynamic button in that case
