Master/Detail Icon Missing - No JavaScript Errors, Relationship Configured Correctly

Hi everyone,

I've been struggling with this issue for quite some time. Initially, I thought it was caused by migrating my project from ASP.NET Maker 2020 to 2025, but after further testing, I've realized that's not the case.

The problem is with the Master/Detail icon that should appear in the row for navigating to related detail records.

In my old project, the icon is displayed correctly and works as expected. However, in the new project, the icon is simply not generated or displayed at all.

Here are the things I've already checked:

  • I am using a licensed version of ASP.NET Maker.

  • There are no JavaScript errors in the browser console.

  • The project does not use user security, so it's not a permissions issue.

  • The Master/Detail relationship is configured correctly (the relationship appears in the Master/Detail setup).

  • The tables and foreign key relationship are the same.

The pages work normally otherwise, but the Master/Detail icon/button is missing from the list page.

Has anyone experienced this before or knows what could prevent ASP.NET Maker from generating the Master/Detail icon?

Any suggestions would be greatly appreciated.

Thank you!
