We have the need to show master and detail rows in an aligned, tabular format, similar to how the TreeList displays them. Currently, in our grids, we use some "hack" jQuery to achieve this after Kendo renders its child table. (We remove the child rows which kendo rendered in a sub table, place them in the main table right after the parent, and clean up the debris). This is the only way to ensure column alignment, and have re-sizable columns work, etc.
Using the TreeList isn't an option currently, because we want to use some other features of the grid, such as paging and batch editing. There are obviously several more features supported by the grid which don't exist currently in the TreeList.
It would be great if I could simply configure the grid to render detail rows this way.
