Lable Toggle

[LanceCrumbliss]

Hi there,

With the new dynamic labeling in v3.2, is possible to actually toggle the visibility of labels (and not just for point features), not just set their placement location?

In order not to see the label you can set the LabelClasses to null.

For example starting from the dynamic labelling sample, you can toggle the labels visibility with code like:

private LabelClassCollection _labelClasses; private void ToggleLabels_OnClick(object sender, RoutedEventArgs e) {     ArcGISDynamicMapServiceLayer dynamicLayer = MyMap.Layers["PopulationDynamicLayer"] as ArcGISDynamicMapServiceLayer;      if (_labelClasses == null)     {         _labelClasses = dynamicLayer.LayerDrawingOptions[0].LabelClasses;         dynamicLayer.LayerDrawingOptions[0].LabelClasses = null;     }     else     {         dynamicLayer.LayerDrawingOptions[0].LabelClasses = _labelClasses;         _labelClasses = null;     }     dynamicLayer.Refresh(); }
