I guess my point is more along the lines of, "Why take away something that's working just fine and so many people have already implemented"?  I'm not really looking for any improvements as it seems to work just fine the way it is.  Your comment on searching bing/google for tutorial & source code isn't even necessary with the current toolbar.  It's there. You add it, wire it to your map and done.  This all gets back to my main point, and I think Patrick's point too - Why take away something that aready exists and works just fine? Why is any code deprecated, someone will always be using the code in question. But I am sure ESRI have good reasons 🙂 Maybe one less control for them to support - although a very basic control with little that can go wrong Reduce the overall download size of the toolkit assembly Encourage more interesting and individual websites instead of many ESRI sample site clones Only ESRI Silverlight team can answer your question. But the effort involved to keep your App the same is very little - download the code from Codeplex and add it to your app - 30 minutes work ... View more

To add my £0.02 worth I'm with ESRI on this one, basic control that anyone can create I would much prefer they invested time in better and faster mapping functionality 🙂 than basic controls you can spend 5 minutes searching on google/bing and find a tutorial & source code for. As Dominique has pointed out the code is on codeplex, so no big deal to take the code and add it to your own control library, then point your xaml to this control - very small job Cheers Chris ...

just in case anyone is interested, this is how I implemented it... 1) Added a trigger to InvokeCommandAction on my ToggleControl, this fires on click event 2) Created ReInitialiseLayerCommand on ViewModel -----a) this recreates the layer, -----b) deletes the failed one from LayerCollection -----c) inserts the new one at the original collection index -----d) raises relevant propertychanged event 3) Created ConditionalExpression on trigger, this is bound to Layer.InitializationFailure property using a ValueConverter to convert from Exception to boolean, so when this evaluates to true it will invoke the  ReInitialiseLayerCommand when the user clicks the ToggleControl 4) Added Image (indicates no internet connection/network problem) to content of ToggleControl, visibility = collapsed - 5) Bound the Image to Layer.InitializeFailure using ValueConverter when evaluates to true Image is set visible indicating to the user that there is an issue with the layer A little convoluted but works well Chris ...

Hi Thanks for the responses, apologies for not getting back sooner - app releases & deployments taking priority 🙂 Reflector is indeed a great app InitializationFailure, InitializedFailed & IsInitialized - understand they are events properties etc - I posted at the end of the day and in a rush so may have been a typo in the original posting 🙂 Here is the scenario... 1) ItemControl ItemsSource is bound to a LayerCollection 2) Layers are loaded at runtime in code behind from a config file into the LayerCollection, the available layers change by user group 3) There maybe 20+ layers available for the user to select from 4) Each layer item in the ItemControl contains a ToggleControl to switch layer visibility problem... 1) 1 layer out of 20 fails to initialize 2) the ToggleControl that is bound to the layer when toggled to set the layer visible fails to set the layer visible because it is not Initialized 3) if the layer has failed to initialize then the ToggleControl needs to be able to reinitialize the layer - this wont work as you are not able to reinitialize the layer What I need is for the ToggleControl when toggled to detect initialization failure of a layer and for the layer to be deleted from the LayerCollection if it failed to initialize. The Layer will then need to be recreated and inserted into the LayerCollection at the same index I have a few things to try - will get back at some point if I get a solution that doesnt involve the user reloading the page Still baffled by the IsInitialized meaning it only attempted to initialize :S and not being able to try and reinitialize the layer in code Chris ...

Ok it works with a simple polygon, but if the geometry is a circle or a freehand line that has been closed to make a polygon it produces no results once the map has panned beyond the dateline. ... View more

Hi Can you classify your data in your Map Document (MXD) and use a Dynamic Map Service or does the classification need to be dynamic and on the client? If dynamic and client side then you could take a look at the following link to get an idea of how to create a class that will allow you to classify your data...(I think this is part of GeoTools  I believe it is opensource but check the licensing oh and its in Java but should be simple to convert to .Net) http://www.ccg.leeds.ac.uk/projects/medaction/medact2/medactionservlet/WEB-INF/classes/uk/ac/leeds/ccg/geotools/classification/NaturalBreaks.java Chris ...
