Hopefully this will be super easy.

I have a dropdown list component whose data property changes dynamically through binding.

Is there a way to make it automatically default to row 0 of the dataset? I could do it through scripting, but would rather not.

Thanks,

Mike

You can bind the selected value property of the dropdown to the following expression:`try({Root Container.Dropdown.data}[0,0], -1)`

Thanks.

One more question I had, is if there is a way to bind something to ‘No Binding’ in scripting.

for example

if  
(  
boolTag  
, [Client]tag  
, don’t bind to anything  
)

No, in that case it would be better to set the selected value through scripting somewhere else.
