Question
I do some acutalizations of values in my grid with these event handlers, but OnTimeItem_StartValueResize and
OnTimeItem_StopValueResize are never called?
MainGantt.OnTimeItem_AfterMove += new TimeItemEvent(MainGanttTimeItemManipulation);
MainGantt.OnTimeItem_StartValueResize += new TimeItemEvent(MainGanttTimeItemManipulation);
MainGantt.OnTimeItem_StopValueResize += new TimeItemEvent(MainGanttTimeItemManipulation);
If found Entry Q10044 – FAQ: StartValueResize, but you didn’t answer the concerns that said “but for some reason it wont work” and gave a workarround for this special case?
Answer
(Andreas sent me a sample to work with because I could not repeat this problem)
I changed the code you had in your sample to this:
void MainGanttTimeItemManipulation(Gantt aGantt, TimeItemEventArgs e)
{
if (DragStartedAtCell != null)
{
GridNode TimeItemsNode = e.TimeItem.GanttRow.GridNode;
if (MainGantt.MouseMoveKind == MouseMoveKind.resizee || MainGantt.MouseMoveKind == MouseMoveKind.move )
{
TimeItemsNode.GetCell(3).Content.Value = e.TimeItem.Stop.Add(e.Diff);
}
if (MainGantt.MouseMoveKind == MouseMoveKind.resizew || MainGantt.MouseMoveKind == MouseMoveKind.move)
{
TimeItemsNode.GetCell(2).Content.Value = e.TimeItem.Start.Add(e.Diff);
}
}
}
}
So what the new code does is:
#1 check if what kind of move-op it is and decide if we need to update any or both cells (Start and Stop)#2 If we shall update we update with the value compensated with the Difference that is about to be applied (.Add(e.Diff));
