Hi,
You can get this working in couple of ways:
1) You can use a custom comparer for that particluar Grouped column and use an ArrayList.sort to arrange the values based on the up / down navigation. Grid will auto-arrange the groups. Below is a sample that moves a group when you press up or down arrow:
WindowsApplication45.zip2) You can use an unbound column and have a summary displayed in the caption and can sort by summaries in caption. You can control where the Group can be moved by storing the Group info and the unbound column values in a hash table. Related samples:
