Scripting Tools: Setting parameters so that one or both must be answered

AlfredBaldenweck

I'm trying out a script that does two related functions.

I have it set up so that either function can run by itself, or you can run both simultaneously.

My parameters are as follows

1. Input GDB
2. Run Function A? (toggle)
3. Output Location (Function A)
4. Output Location (Function B, essentially acts as its toggle)

Is there a way to make it so that either B or D, or both of them together, must be answered? 

Basically I'm trying to avoid the users running the tool in such a way that neither function runs.

Similarly, is it possible to make Parameters have conditional visibility? Like, C only shows up if B is answered or toggled.

Thanks!

Hi Alfred,

What you are after is Script Tool Paramter Behaviour. You can set the Parameter[i].enabled = True/False to enable disable a parameter. You can apply a condition on Parameter B's values to dynamically enable/disable Parameters C/D.

 

The logic would be something like the below:

Parameter B should be a MultiValue list with your selectable (filter) options: Function A, Function B

Parameter C has a dependency on Parameter B and is enabled when Parameter B has Function A in its list of values. 

Similarly, Parameter D has a dependency on Parameter B and is enabled when Parameter B has Function B in its list of values.

If both Function A and Function B are selected in Parameter B, both Parameter C and D will be selectable.

Hope this helps!
