Hello everyone,

I try to disable a custom "send" button with PowerFX when a document (field with File Type) is not added to the form. I tried various options within the Visibility field:

!IsBlankOrError(Self.Selected.Item.FileAttachments)
!IsBlankOrError(Self.Selected.Item.Document)
!IsBlankOrError(Self.Selected.Item.Document.FileName)
!IsBlankOrError(Self.Selected.Item.Attachments)

But it doesn't seem to work.

Does anyone has suggestions?

Kind regards,
Elowy.

Hi @Slowytech,

We also faced same issue with Power fx formula.

But if you still want this functionality, then instead of Power Fx formula, you can go for solution using Ribbon workbench to disable the button if the document is not present.

Below are the steps –

Create one solution and add the entity in which you want to add the ‘Send’ button.

Note- Don’t add anything else in that solution. It should only contain the entity in which you want to add the button.

Open the Ribbon workbench and open that solution.

Add the button in the main form and provide the name to that button.

4. As you want to display the button if the file is present then add the ‘Enable Rule’ to that button.

5. Provide the field logical name and then publish the solution.

Result –

When the file is not present then the button is hidden.

When the file is present then the button is visible.

Thanks!

Unfortunately not. I ended up with making the document field mandatory. And to prevent the button from being visible on a "new" form, I added the following to the visible condition of the button: "And Self.Selected.State = FormMode.Edit)" .

Maybe that helps.

Kind regards,

Elowy.
