How to get "Add New" button on empty detail grid?

I have a Master Form with a detail grid.

When there is no detail record, the grid shows the Quicksearch field but no Add New button, so there is no way to add a new record.

What’s the solution?

Thanks

You know probably but as I understand your question …

Did you link your detail grid with a form ?
The “Add New” button will be accessible in the link parameters.
In other words the “Add New” will appear when a grid is linked with a form.

I found out if you save the record in the master form the new button appears in the empty detail form.

Sort of; I found that I need to reload the browser after creating and saving the master record. Then new details could be added. Very klunky and counter intuitive unless one knows the kludge.
