Goodmorning,  
I use a dropdown list with property selected value that binding a plc variable integer.  
This variable is update from a script event, when change property selected value of dropdown list.  
All the time that I open windows with dropdown list, value of property Selected Value is -1.  
Why???  
How is possible memorize the selected value of dropdown list when close and reopened window with dropdown list???

Thank you

you could bind the selected value with the tag and just not poll so that it only calls once on openeing the screen
