From what I understand, if I have a grid with EditMode="EditForms" with a WebUserControl and everything works correctly, the only thing I have to change for this WebUserControl to turn into a PopUp windows is the EditMode="PopUp".
The reason I ask is that I have already tried this, but I get no PopUp screen.
You can see the attached screen for what I get instead (third record).
I would appreciate any help.
