Hi,

The flowchart I have is using Polyline arrows, SegmentCount is 1, SnapToAnchor property is set to saOnCreateOrModify.

I allow the user to add multiple controls points to the arrows between boxes by dragging them, however, I also want to provide the functionality where they can just remove all the control points (apart from 2 needed for a 1 segment arrow) by selecting an arrow and choosing a menu option.

Here is the code I have been trying to do this with:

foreach (Arrow arr in this.FlowChartMap.Selection.Arrows)
{
arr.SegmentCount = 1;

int NoOfControlPoints = arr.ControlPoints.Count;

for (int i = 1; i < (NoOfControlPoints - 1); i++)
{
arr.ControlPoints.RemoveAt(i);
}

arr.UpdateFromPoints();

}

However, the flowchart appears as a huge X when I run this code. How should I be removing the control points?

Thanks,
Charles

Hi,

That code works when the arrow has 3 control points. However it doesn't work when the arrow has more than 3 control points, the arrow appears to be disjointed/split after running the code.
Also, setting to SegmentCount = 1 does not change the no. of the control points, the number of these always stays the same.

Any ideas?
Charles.

Yes it is polyline.
It has originally only one segment and the user can then drag it around to add more.

Yes that's it !
I set AutoRoute to false and that resolves it.

Thanks a lot,
Charles.
