  I have an application using RadMap that shows zip code or carrier route boundaries (MapPoygons) in a DynamicLayer.  I have ExtendedData properties for each MapShape.  I want to use the Colorizer.  Can you show me how to intialize the colorizer when the DynamicLayer is added in code behind?
  
  Right now when I find the DynamicLayer using RadMap.FindName the colorizer evaluates to Nothing.  So I am unable to set the Colorizer.ExtendedPropertyName or call Colorizer.Prepare().
  
  Thanks
  Sumith

  I created a New ColorMeasureScale with the required properties and set DynamicLayer.Colorizer = ColorMeasureScale and everything is working alright when I set the Min and Max values manually.
  
  Since the MapShapes are created in the DyanmicSource what is the appropriate time (event) to call the Colorizer.Prepare method to set the Min and Max values?
  
  Thanks

  Hello Sumith Jayasuriya,
  
  The DynamicLayer gets items by request so you never know whether all items have been read or not. So you can't use automatic methods to calculate Min and Max values with DynamicLayer, because it will provide different results depends on the number of items that have been read already. The only way is set MinValue and MaxValue properties manualy. For example, if you get data to show from the SQL server then you can execute 2 requests to calculate Min and Max values before the actual data reading.
