How to go into different windows using dropdown list?

Ignition
1

Hello,

I want to know how to use the drop down list. Is it possible to go to another window using the drop down list instead of using the buttons?

For example, I have two windows for Trends namely Trend 1 and Trend 2. I made two columns, both for string.

Col1 Col2
Trend 1 Trend 1
Trend 2 Trend 2

Col1 for the windows to open and Col2 is the display name. Now by selecting Trend 1 in the dropdown list, can I open the Trend 1 window? Please tell me how to do this?

All you need to do is add a propertyChange event to the dropdown list that opens a window when the user selects a different option. Add the following script to the propertyChange event handler:if event.propertyName == "selectedStringValue": value = event.newValue if value != "": system.nav.openWindow(value)You can use the following to swap:if event.propertyName == "selectedStringValue": value = event.newValue if value != "": system.nav.swapTo(value)If you get any errors post the full details of the error.

Thanks a lot Travis, it works fine now.

There is a problem with this script.
If I have several windows to select and i selected one of them before and then i returned to specific option again there is no new Value because it selected before.
How can I initialize selectedStringValue after clicked on it?

I figured out, after selected I just put 0 inside selectedValue.

What is it complaining when it works? How can I get rid of this message?

Thanks a lot.

Never mind…it looks like you have to have the if condition for event.newValue != “” in there!
