The provided code snippet is greatly appreciated. When you change the value in a grouped grid the GroupDescriptor is not automatically reevaluated. This is why you need to do it manually. Please refer to the updated Button_Click event:
privatevoidradButton1_Click(object sender, EventArgs e)
List<GroupDescriptor> groups = new List<GroupDescriptor>();
this.data.First().children.First().Prop2 = 1;
if (groups.Count > 0)
I hope this helps. Do not hesitate to contact us if you have other questions.
