Hi Matthew,

thanks for the answer.

I would really appreciate being able to set the stroke of the zooming rectangle.

Regarding the second Point, i did something like this (example for the x-axis)

1) in the Chart mouse down Event i set a flag, isZooming, to true

2) in the Chart mouse up Event, i reset this flag to false

3) in the Chart mouse move Event, i currently do this:

            if (isZooming)
            {
                if (!chartSpectrum.ViewportRect.Contains(e.Location))
                {
                    if (e.Location.Y > chartSpectrum.ViewportRect.Bottom)
                    {
                        System.Drawing.Point pCurrent = Cursor.Position;
                        pCurrent = chartSpectrum.PointToClient(pCurrent);
                        pCurrent.Y = (int)chartSpectrum.ViewportRect.Bottom - 1;
                        Cursor.Position = chartSpectrum.PointToScreen(pCurrent);
                    }
                }
            }

this now has to be done for all sides of the viewport rect

Thanks thomas

Hi Matthew,

it took a while, but I just applied SR 2088.

Re-Testing the application showed no side effects at all.

And using the PreviewPathStroke Property works like it should.

This really helps me.

Thanks for implementing that.

Hi Thomas,

Glad to hear it is working and the re-test looks good.  Thanks for bringing the color of the zoom rect to our attention! 

Thanks for adding the PreviewPathStroke property, it is exactly the feature I am looking for.  I am currently on version 2015.2, I guessed this is not available until later versions.  Which version did this property started to appear in?  If upgrading is not possible immediately, are there any interim solutions that I can do in the meantime, like modifying a css or a js file?  Thanks.

The PreviewPathStroke property is present in the latest service release of 2015 Volume 2 and 2016 Volume 1.  It can also be expected in the release of 2016 Volume 2.

Thanks Alan.  I just realized I am on the wrong forum, I needed this for the igniteui igDataChart.  We don't see such property in the 2017.1, do you know if such is available in igniteui?  Thanks.
