Posted on by ashishkapur

Hello Experts,

I have a power pages multistep form based on entity A. I have a subgrid displayed that saves child records for entity b in one of the steps. Is there a way where in mutistep form I have conditional step based on records in child entity B?

Thank you

Hi @ashishkapur,

is the condition like if there are child records or does the condition shall check which kind of child records are associated?

I think what you want to achieve is not available via OOTB.

Something what could work is setting up another yes/no column and let the user click to kind of force the conditional multi step. Maybe that could work in your case.

Hope that helps.

Not out of the box. You may be able to work around it, but it may depend on exactly what you are needing to do.

As suggested by Lucas you will want a field to hold a value that indicates which step to go to next, but then it depends e.g.:

if it is just that the Subgrid contains a record you could use JavaScript/JQuery to populate the flag

if it is more complex you may need to write a realtime plugin or workflow (may also be able to use Power Pages Flow - but not sure about it) to update the Flag

Hey @Lucas001 and @Fubar

Thank you for the replies. I need to validate against what kind of records are in child entity.
My site is for pet license renewals. The child entity will hold multiple licenses for each application that uservwants to apply. Can a dataverse plugin (pre operation on update) be executed on each step of multistep form even if parent entity is not changed? If so, then I can perform logic and store true/false in a field of parent entity. I can then use this field in condition step. I need to show certain sections of application based on license type.

Hi @ashishkapur ,

You need to create a rollup field to indicate your subgrid values or create plugin to loop on the create, delete or update any of the records at the subgrid to update the field on thee parent entity, then use this field on the parent entity on your conditional step.

I'm not 100% sure if the pre-operation would work or not, but it doesn't have to be pre-op it can be post op as long as it is realtime - the Next button saves the record prior to the next Condition step getting evaluated and pretty sure when you Next the condition is reevaluated each time irrespective of if there is dirty data or not.

Another alternative may be to Disable the submit/next button, add an event listener on the Subgrid "loaded" (or a mutationobserver) and then use that event to run a Portal WEB API call (or maybe even a Portal Flow) and use it to validate and if valid re-enable the button etc.
