Help with expression.

[JCarlos]

Hello,

I need help with an expression for a display name in a form view.
I have a "SALES" table with a "SALES" menu view with a submenu with the types of sales (Quotes, Invoices, Delivery Notes...), I want it to show me the name of each type of document, for example in the view detail in display name I put [Document Type] and it shows it fine, but the same thing doesn't happen in the form view, it tells me that it can't find the [Document Type] column

What I can do?

Thank you

A form view's display name expression cannot reference values directly from the row being edited (especially if it's a new row not yet saved to the data source). If you can derive the document type from other data, use that in your display name expression.

Hi!!! dbaum

I don't know how to do it because the type of document can vary.

It depends if I select a document type or another, the value changes and I don't know how to refer to it.

You can't. You would have to set up individual form views for each document type.

Ok,

thank you very much.
