Hi Matthias,
The child tables are known only when the row from the parent table is selected and the sorting information will be lost once you change the selected row from the parent table. But until you did not change the selected row in the parent table, even if you leave the child grid and enter again it wont lose its sorting information. So, if you want to keep the sorting of the child table even after changing the selected row from parent table, you have to store it and apply it explicitly. Here is a sample.

Calvin.
