How to reset Drop Down control value (NOT uidropdown) - with example
显示 更早的评论
I have the following code (showing picture because I can't display the drop down here)
I can't find a way to make sure that each time the code is run, the drop down is set to the first item in the list. The second line was my attempt but it doesn't work. Is there a way to do this (in the Configure Control dialog the default is set to "Acetamide". Sample code is attached.

Hi Paul,
I understand that while using a Live Editor Drop Down Control when we change the selected value in the dropdown during execution, and then re-run the script, the dropdown remembers the last selected item instead of resetting to the default value.
Live Editor controls in MATLAB preserve state between runs, they do not reset automatically even if we have specified a default value in the Configure Control.
If we are looking for the UI itself to reset visually, that is not possible with Live Script controls alone, we would need to use App Designer or uidropdown in a uifigure.
A MATLAB Central Answer that highlights this point:

Hope this helps!
