Conditional dropdown selection to hide and show items of fields

Posted on by Community Power Pla... Microsoft Employee

Hi guys,

I'm new to Power Apps, I'm facing this issue.

This is a PA form when I select Projects value in Time entry field the below two fields are enabled Project and Project Role but when I change to other option like this

Project and Project role are hidden for other option selected except Projects option in time entry field.

Everything is working fine but problem is coming when I edit any existing records of list and try to change the Time Entry field option when I'm changing the option from Projects to other options the below two fields disabled automatically which is fine but when I save this form after making changes the value of Project and Project Role remains in list which was existed for Projects option before editing.

So what I need here when I edit the existing records so value of Project and Project Role also wipe from SharePoint list when I select options other than project in time entry field.

Thanks in advance.

Hi @Anonymous :

Do you need such a function:

When you change the value of "Time Entry Type" of an item with the value of "Project" in an existing "Time Entry Type" field to other options, clear its "Project" and "Project Role" values.

Is the project a drop down control or a combo box control?
Is Project Role a drop down control or a combo box control?

I assume project and project role are all combo box control.Please try to set their DefaultSelectedItems to

If( TimeEntryType.Selelcted.Value ="Project", Parent.Default, Blank() )

note:please modify the formula according to your actual situation

Best Regards,

Bof
