Thingworx List Widget auto trigger Selected row changes event

[vxba]

I have a Combobox list and binding the list data by a service call after this service called I invoke another service to get selected item and binding again to SelectedText properties of Combobox then the event selected row change of Combobox will auto-trigger.  

How can I avoid this case, because this action will trigger another service in my logics    

Thanks All!

If you absolutely need

Service Complete -> Get info -> Set SelectedRow

but need SelectedRow not to trigger the first time, you could .. cheesy as it may be, use some boolean flag to indicate 'First load' and use that into a validator then Selected Row Changed, to either toggle First load or fire the service you want.

could you maybe add a button to run your service and not bind the selected row change to anything at all?

Hi @slangley  and @PaiChung.

I have attempted to implement this solution but. the big problem is I cannot identify when is the first load

Do you have other solutions or some demo?

Thanks!

[PaiChung]

Hi, one way to 'determine' first load is to just have a hidden boolean value or boolean mashup parameter with a default value.

Then you can use the Expression/Validator function to check that value and update it accordingly
