Form Validation with custom card not working

@LukeW-MSFT

This is driving me nuts. Can anyone please advise me on what the issue is here and how to overcome it?

Created an app from a Sharepoint custom list
Deleted the default label then pasted an existing label into the data card to keep styling consistent
Deleted the text input box and pasted in a dropdown menu to keep styling consistent
- Dropdown Items property set to:
- ```
[" ", "Completed", "Completed w/ Comments", "Exceptions Taken"]
```
Set the data card Required property to true

If I leave the dropdown value set to " ", then SubmitForm(), no Error Message appears and the form is successfully submitted. Text boxes within the form error-out correctly (see below), it just seems to be the dropdown.

I cannot for the life of me figure out why.

Hi @ericonline,

Could you please share a bit more about your app's configuration?

I have made a test on my side and don't have the issue that you mentioned. If I leave the Drop down (new pasted one) control empty, when I submit the form, the error message shows up as below:

On your side, please check if the Update property of the DataCard control associated with the Drop down control (new pasted one) is set to following formula:

Dropdown1.Selected.Value

Note: The Dropdown1 represents the new pasted Drop down control on your side.

In addition, please also check if the Error Message Label is existed within the DataCard control (Associated with the Drop down control):

If the Error Message Label is not existed within the DataCard control, please add a Label control within the DataCard and set the Text property of this Label control to following formula:

Parent.Error

Best regards,

Kris

I really appreciate your detailed follow up. Here are my results. Issue still present:

Dropdown Items Property set to:
[" ", "Completed", "Completed w/ Comments", "Exceptions Taken"]

Error message is present with Text Property set to Parent.Error
Data Card Update Property set to: (I need to report Comments if they are added)
Concatenate( prejobSafetyChecklist_input.Selected.Value, "; ", If( IsBlank( prejobSafetyChecklistComments_input.Text), "No comments", prejobSafetyChecklistComments_input.Text))
Data Card Required Property set to True
Execute SubmitForm(formName) and no Error Message is displayed for the Data Cards in Question (there are 14 of them). The first 9 Data Cards error out just fine. But cards 10-24 do not error.

Its almost like the " " option is being seen as a text value. I've tried "" and Blank() as options as well. No Go.

If I slap a new version of the Data Card in and mark it Required, it errors out no problem.
If I copy in the dropdown menu AND leave the Update property to dropdown_1.Selected.Value, everything errors out correctly.

If I try to copy over the comment box and change the Update Function, NO GOOD, error message disappears.

What is wrong with my UPDATE Function where it overrides the REQUIRED Function of the Data Card?

I know this is 6 years late, but it may help someone in the future. I believe your update statement is always returning a non-blank value even if prejobSafetyChecklist_input and prejobSafetyChecklistComments_input are blank. If these fields are blank, Concatenate() will return "; no comments" which passes the Required validation. The Update should be changed to:
If( IsBlank(prejobSafetyChecklist_input.Selected.Value), prejobSafetyChecklist_input.Selected.Value, Concatenate( prejobSafetyChecklist_input.Selected.Value, "; ", If( IsBlank( prejobSafetyChecklistComments_input.Text), "No comments", prejobSafetyChecklistComments_input.Text)))

so that it only concatenates the values if the drop-down has a value.
