Hi, As a fan of being able to declare my symbols directly from XAML, I've implemented an extended PictureMarkerSymbol to support this. As a side benefit, I ended up being able to set the symbol from any ImageSource, including DrawingImage. This provides me with the ability to define symbols from Path or other geometries to create richer symbols, without having to create my own fonts, and still make things scale. I realize too rich symbols may cause clutter in the map, so it is still important to keep it simple. If anyone sees a problem with this implementation (like it won't be supported in the future), points of improvement, or anything else, please let me know. ... View more

Hi, I would like to create some sort of layer list, where I can toggle visibility of layers. The display should also include group layers. I tried using the Legend control in the toolkit, but it only displays a flat structure. Looking at the source code, there are some layer options, which includes ReturnGroupLayers, but I'm not able to set this. Is this limitation a related to "not yet implemented", or something that will not be supported? I figured I could hide display of symbols, and only display the tree structure of the layers, and filter out the layers I don't want using the Refreshed event. I'd like to support both tree structure and/or expanders for the group layers. Setting IsHidden = false if IsGroupLayer is true in Refreshed event doesn't have any effect. Is this something that will be supported in the near future, or do I have to modify the sources myself to support this? ... View more

Hi, While playing around with the MVVM approach for the controls, I discovered something I believe is a bug. I was trying to display multiple viewmodels where the DataTemplate contains a MapView in an itemscontrol (TabControl), I discovered that the map is not displayed. I get an empty map, which is of no real use. It is just an empty control with the ESRI logo. I get the same result using a ContentPresenter. The following should be sufficient to reproduce. SomeClass is just an empty class in this example. Having a map property on this class, and binding the MapView.Map to that property doesn't work either. <Grid>     <Grid.ColumnDefinitions>         <ColumnDefinition Width=".5*" />         <ColumnDefinition Width=".5*" />     </Grid.ColumnDefinitions>     <esri:MapView Grid.Column="0">     <!-- This map works -->         <esri:Map>             <esri:ArcGISTiledMapServiceLayer ID="h" ServiceUri="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer" />         </esri:Map>     </esri:MapView>     <ContentPresenter Grid.Column="1">     <!-- This map does not work -->         <ContentPresenter.ContentTemplate>             <DataTemplate DataType="viewModels:SomeClass" >                 <esri:MapView>                     <esri:Map>                         <esri:ArcGISTiledMapServiceLayer ID="h" ServiceUri="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer" />                     </esri:Map>                 </esri:MapView>             </DataTemplate>         </ContentPresenter.ContentTemplate>         <ContentPresenter.Content>             <viewModels:SomeClass />         </ContentPresenter.Content>     </ContentPresenter> </Grid> I have to admit that this is rather inconvenient for what I need to do in my application, so I was wondering if there is a suggested workaround, and if this is possible to fix somewhat shortly? ...

Hi, We have an existing application using Runtime for SDK, and I'm doing some research on how to migrate to the .NET Runtime. Our application uses MVVM. These are the requirements: - Multiple maps, as documents, as in Visual Studio - All maps contains the same layers and Graphics - Visibility of categories of objects should be able to toggle individually per map (Display all vehicles of type x, all alarms of type y) - through checkboxes made available for the user. - Selecting an object in a list should select it in the map, and make it visible Current Runtime for WPF implementation: - Viewmodels are added to a "MapManager" - Geometry is retreived from the item itself (IMapItem.GetGeometry) - A new Graphic is created per map, and graphics duplicated x number of maps - Updates to geometry is updated in all maps - PropertyObservers listen to IMapItem.IsSelected to synchronize selection - Custom renderers have been implemented to return symbol based in IsSelected attribute, or IsVisible set for item category - Whenever a new map is created, it is added to mapManager, and then added to the UI (and graphics are duplicated) If I can have one map, and multiple map views, that would be great. Seems there would then be an issue with setting visibility of different categories, as it would then be the same renderer/layer/graphics represented in each map. I may be able to use the same graphics in all maps (assuming there are no restrictions against that, but there doesn't seem to be). Changing visibility of layers would disable the ability to display selected graphics. Since there are no public events being raised related to Graphics.IsSelected, I'm not quite sure to reflect selection back to the MapItem, unless MapItem derives from Graphic. Any suggestions to how to proceed? ... View more
