Changes in custom map colorizer data are not reflected in the corresponding vector layer

created 9 years ago

Hi,

I have a VectorItemsLayer with a custom colorizer inheriting MapColorizer:

C#
public class CustomColorizer : MapColorizer  
{  
    public string ColorName;  

    public CustomColorizer(string colorName)  
    {  
        ColorName = colorName;  
    }  

    public override void ColorizeElement(IColorizerElement element)  
    {  
        MapBubble bubble = element as MapBubble;  
        if (bubble != null)  
        {  
            if (bubble.Attributes[ColorName].Value != null)  
            {  
                int color = (int)bubble.Attributes[ColorName].Value;  
                element.ColorizerColor = Color.FromArgb(color);  
            }  
        }  
    }  
 }

The data of the map is a ListSourceDataAdapter. When I modified the color of an element of the source data, the color of the bubble don't change. Is it possible to refresh the bubble color ?

Thanks,

Olivier

    Hi Olivier,

    We have already fixed this issue and the fix will be included in the next maintenance update: Changes in map colorizer data are not reflected in the corresponding vector layer. As an immediate workaround, set the VectorItemsLayer.Data property to Null and re-assign the Data storage to force refreshing the map.

        We will examine this behavior in greater detail and check for a suitable solution. Your patience is appreciated.
