Seeing this only in Chrome.
The master grid is order when expanded it displays the items in the order.
The problem is when the order detail rows are expanded and the rendering is greater than the master grid height.
The rows that are outside of the height of the master grid, cannot be selected, the edit delete button will not work.
If you make the master grid height much large so that all detail rows are in the master grid "frame" the detail rows can be edited.
This is not present in FireFox or IE.

Hi Scott,
Could you please link to a sample page where this happened or provide the php code with this problem?
Thanks,

Here is the current code - I have increased the master table heightfrom 500px to 1000px
The problem is when you expand a detail ( 2nd level grid) and then expansion renders over the max master table height, the rows in the detail grid outside of that area cannot be selected or buttons clicked on for edit.
