Show Arrows with/without .Text

Hello,
I gladly switch on and off the Arrow characteristic "Text" on push of a button. 

My beginning:  I provide two identical Arrows for a connection (one with Text the other one without).  Then I would set the Arrows visible=true/false with the help of a foreach loop . 

For me-seems that this beginning is not really good.  Has you a suggestion?

tnx lemon

Hello,

Why don't you just set the arrow's Text to an empty string and restore it back when needed ? You can store a copy of the text in the Tooltip or the Tag property and get it from there when it must be shown again. Thus you will have the text in two places, but that's better than keeping a second arrow for just showing and hiding text.

Another option might be to set the TextColor to a transparent one, having an Alpha value = 0. I haven't tried this, but it's very possible that it works...

I hope that helps,
  Stoyan

Hi,

it works!

But now:
two foreach-loops can be a obstacle for good performens. How can I change all arrows on _flowChart at one time?

foreach(Box b in _flowChart.Boxes)
{
  foreach(Arrow a in b.OutgoingArrows)
   {
     a.TextColor = System.Drawing.Color.Black;
   }
}
_flowChart.Print();

Hi,

You must still use at least one loop on the Arrows collection:

foreach (Arrow a in _flowChart.Arrows)
  a.TextColor = ...
