David,

It's been so long since I've used linkmaster grids, but make sure you have the parent table workarea selected and that it's the initial selected alias of the DE.

>LinkMaster WPage

>RelationalExpr Wpage.wpageid

>Now all of a sudden the grid doesn't show the records belonging to the parent. (except intially) It's stuck!
>If I put a command button on the form with "this.parent.grd1.refresh()" as the click event it comes good when clicked. And it refreshes with every "Next" "Prior" etc after that. If I put the same command in the refresh of the page, or in the activate event of the page it fires but doesn't work. That's weird! The data environment hasn't been changed at all from when it was working.
