GraphicsLayer labels disappear on zoom-in/out

AlexanderGleyzer — Sun, 17 May 2015 15:22:42 GMT

I've been trying to use GraphicsLayer's Labeling property and have defined LabelClasses.

I need the labels to be constantly visible, regardless of their overlapping or of map scale.

Unfortunately, when I zoom out - some graphics' labels disappear and don't reappear even if I zoom back in.

I've used the following settings:

LabelPosition = LabelPosition.FixedPositionWithOverlaps

DuplicateLabels = DuplicateLabels.PreserveDuplicates

LabelPlacement = LabelPlacement.PointCenterCenter

LabelPriority = LabelPriority.Highest

to no avail.

I'm attaching 3 screenshots:

1) labels_good: all labels are displayed ok;

2) labels_bad1: some labels missing after zoom out;

3) labels_bad2: some labels are missing after zooming back in to the original scale of 1).

Please, assist.

Alexander Gleyzer.

Hi, Michael.

Attached is a C# project reproducing the problem.

When zooming out a little - some labels disappear.

Thanks,

Alexander.

Hi,

Thanks for the reproducer app, it is exactly what I needed.

I have some good news - whilst I could reproduce the problem you are seeing with the released 10.2.5 product, I am unable to reproduce using the current dev build of the forthcoming 10.2.6 release. We have addressed an issue in this area which appears to resolve the issue you are seeing too.

We anticipate shipping the 10.2.6 release in early-mid summer 2015.

Cheers

Mike
