I have a form (see attached) that allows users to submit visitor details and then displays the result in a gallery below. The user can submit multiple visitors, but the "host" and "Visiting Site" fields will always be the same as the first form submitted. I have this part working with a "LastSubmit.host", etc. formula, which when the form is submitted, it pre-populates the "Host" & "Visiting Site" fields, leaving the remaining fields empty. This works fine, but it would be nice for the "Host" and "Visiting Sites" fields "Display Mode" to switch from "Edit" to "View" to prevent users changing the pre-poplated values, but I cant figure this out.
I have tried...
If(IsBlank(Visitor_Registration_Form.LastSubmit.Host), DataCardValue14_1.DisplayMode.Edit, DataCardValue14_1.DisplayMode.View);
on various canvas and item parameters, but cant figure it. Help.
Hi @StuartSmith ,
Where do you put your If formula?
Could you please share a bit more about the "Host" field and "Visitig Site" field within your SP List data source?
Based on the formula that you mentioned, I think there is something wrong with it. Currently, within PowerApps, we could not assign value to a property of one control within another control.
Based on the needs that you mentioned, I have made a test on my side, please consider take a try with the following workaround:
Set the OnSuccess property of the your Visitor_Registration_Form to following:
Share
Report

Set(SubmittedRecord, Visitor_Registration_Form.LastSubmit)Set the DisplayMode property of the Host ComboBox (DataCardValue14_1) to following:
If(
!IsBlank(SubmittedRecord.Host.Value),
DisplayMode.View,
DisplayMode.Edit
)or
If(
!IsBlank(SubmittedRecord.Host),
DisplayMode.View,
DisplayMode.Edit
)or
If(
!IsBlank(Visitor_Registration_Form.LastSubmit.Host),
DisplayMode.View,
DisplayMode.Edit
)Note: Same logic for "Visiting Site" ComboBox.
Please consider take a try with above solution, then check if the issue is solved.
Best regards,
