Change a data card to read only when in Edit mode

Posted on by LadieKay

I am essentially asking a very similar question to what has been asked before "I am using PowerApps to create a SharePoint Form. I want to have a data card for "Date" that the user can change when they are submitting a new form, but if they click edit in the app, it becomes read only and they cannot change it anymore. Is this possible?"

However, the solution that was given a few years back gets flagged with an invalid argument error:

DisplayMode = "If(SharePointForm1.Mode = FormMode.New, DisplayMode.Edit.View)"

I then found and tried this, and while it doesn't get flagged with an error, it does not seem to be actually making any effect on the function of my form:

DisplayMode = "If(SharePointForm1.Mode = FormMode.New, DisplayMode.Edit, DisplayMode.View)"

Then, I found this answer in these forums, and it sort of works to lock the field when the form is in edit mode, but this includes having the DefaultDate set to "today."

DisplayMode = If(SharePointForm1.Mode=FormMode.New,DisplayMode.Edit,DisplayMode.View)

In short, when the form is edited, it shows todays date, rather than keeping/locking in the date that was entered when the form was first submitted, like I want.

Any suggestions would be much appreciated. I am at a loss as how to further troubleshoot this,

Karissa

Hi LadieKay,

How about you try to use the third formula you've mentioned:
DisplayMode = If(SharePointForm1.Mode=FormMode.New,DisplayMode.Edit,DisplayMode.View)

and update the DefaultDate property to:
ThisItem.YourDateColumn

Hope this helps.

Kind regards,
Nandit

HI Nandit,

I really appreciate your quick response! This might work, but I feel like adjustments would have to be made to the DefaultDate property code you suggest. This is because I already have a code in there that tells the form to autofill with "today's" date, so people don't have to enter it when they are filling out the form for the first time. However, I want this initial entry date to stay the same, so how do I keep the convenience for form users, while having it stay stable/uneditable in edit mode?

DefaultDate = If(SharePointForm1.Mode=FormMode.New,DisplayMode.Edit,DisplayMode.

ThisItem.'Entry Date')

DisplayMode = If(SharePointForm1.Mode=FormMode.New,DisplayMode.Edit,DisplayMode.View)

I am a novice at all this, learning this for work, so I am sorry if this seems like it should be obvious. I truly appreciate the hand holding,

Hi LadieKay,

These sets of should hopefully accomplish what you want to achieve.

DefaultDate = If(SharePointForm1.Mode=FormMode.New,

Today(),

ThisItem.'Entry Date'

)

DisplayMode = If(SharePointForm1.Mode=FormMode.New,

DisplayMode.Edit,

DisplayMode.View

)
