I have been trying a number of different ways to batch edit child rows and click one save button to then save those changes locally and update the associated master rows. I am not using Ajax, ServerOperation is set to false on both grids. My problem is that upon setting the master row cells, the main grid is refreshed, collapsing all my child rows, losing their edits and ultimately only the first row changes are saved. Any advice on how to stop this refresh from happening until my loop is complete?
