PenInput Validation customized with a SharePoint Form

[Julien2]

Hello,

I have customized a SharePoint form through Power Apps and I have added a field called Manager signatures. In this field, I have added a Pen input signature and a button.

What I want to achieve is the following:

• I want to hide the submit button if the signature is blank else it will display. I have set the visibility of the button to false if the SharePoint form is "New". So what would be the function with the signature condition?

If(SharePointForm1.Mode=New,false,true)​

• Besides, I would like to know if it's possible to add a condition to check if the form was already signed by a manager and submitted to hide the Pen Input signature only at "Edit" form action. If so, what would be this condition?

I have tried to implement the following:
1. Set the OnVisible button to the following function which caused an error: (PenInput3 represents my PenInput field)

If(SharePointForm1.Mode=New && IsBlank(PenInput3.Image), DisplayMode.Disabled, DisplayMode.Edit), false,true)

2. I have tried to follow the steps mentioned by Shane but unfortunately, nothing happens.

Pen Input is Blank 

Can someone please explain in detail and provide an example to achieve the following scenario?

Any help will be greatly appreciated.
Thank you.

Hello @WarrenBelz ,

I want to inform you that the visibility of the button is working as expected once, which means for only one record that is signed, but let's suppose I want to add my signature to another record, again the send email button appears.

I expect that because I have to reset the PenInput1 image after the submission or close button in the popup.

Please have a look at the Demo below:

If so, what would be the property to handle this issue?

Looking forward to your response.
Thank you for your support.

Hello @Julien2 ,

Yes - I must admit I never tested that, however it should be easy to fix - just set (as you have mentioned) the variable when opening the pop-up. That way, it will always reflect the current condition of the pen input.

Hello @WarrenBelz ,

I have set the variable to the button that opens the Popup OnSelect property to the following:

Unfortunately, the send email button doesn't take effect to be invisible when opening a new item that is not signed.

What I am doing wrong?

Looking forward to hearing from you.
Thank you!

Hi @Julien2 ,

You need to set the Variable in the screen pop-up

UpdateContext({Popup:true});
UpdateContext({EmptySign:PenInput1.Image})

That way every time you initiate the pop-up the button should not appear as you have set the variable to reflect the current state (empty) of the pen input.

Thank you very much for your support.
The set variable you mentioned in the last post has resolved my issue and worked as expected.
