Hi,

I have problem deleting object from the flowchart.
Here is code:
              try
{
foreach(Arrow obj in objectsToDelete)
{

    if (manager.FlowChart.Arrows.Contains(obj))
{
manager.FlowChart.DeleteObject(obj);
}
}
}
catch (Exception ex)
{
string        s=ex.Message;
}


I have two arrows inside collection objectsToDelete, first one is deleted without problems and second one passes   “if (manager.FlowChart.Arrows.Contains(obj))" but fails on flowchart.DeleteObject with Error:
ex.Message"Cannot remove the specified item because it was not found in the specified Collection."

Could anyone help please?

Thanks.

Enver.

This is  exception stack trace?

you can do it like this:
for (int i = flowChart1.Boxes.Count; i > 0; i--)
{
delete your object;
}

you have 2 obj,boxes[0] is A,and boxes[1] is B,if you delete Boxes[0] A,now Boxes[1] B will change to Boxes[0] B.
