I ran Fiddler while running our SDK sample on Area and Perimeter and I was able to reproduce the negative Area by drawing the polygon in counter-clockwise direction.  This is without any change to the code. When I drew the polygon in clockwise direction, the Area I get is correct.  The best way to avoid incorrect values for Area is to call SimplifyAsync() on the Geometry after draw is complete before calling AreaAndLengthAsync().  You can also try to draw in clockwise direction and you should see the difference in values. This is the link to the Simply sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Simplify Another option is to use the Editor's Add instead of the Draw object, this will ensure that the polygon is simplified before adding to your layer. Look at the Add Polygon button in this sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#EditToolsExplicitSave If you will be using this approach on GraphicsLayer, the CommandParameter need to be set to the polygon symbol, the GraphicsLayer need to have its ID property set, the button's DataContext need to be set to an Editor with Map property bound to the map that contains this GraphicsLayer, and LayerIDs property set to the ID of the GraphicsLayer that will contain the polygon. ...

Image Source property expects a BitmapImage. If your image URL still need to be formed from a graphic attribute, you can create your own image converter that will do this type of extra handling. In your MapTip, you can do: XAML <Image x:Name="OverviewImage" Source="{Binding [ProjectID], Converter={StaticResource imageConverter}}" /> Provided you have an ImageConverter that performs this conversion from string to BitmapImage string imageUrl = string.Format("Images/{0}.png�?�, value); return new BitmapImage(new Uri(imageUrl , UriKind.Relative)); ...

Please try the following sample. I tried to use your same approach of defining the Editor and Binding in code-behind and also add the layers at run-time.  For simplicity, I only have ClearSelection, graphics in my sample are selected as soon as the feature layer update is complete.  I added MouseLeftButtonDown so you can check which graphic belongs to which layer and whether it is infact, selected.  I also added ZoomTo the layer's extent so you can verify visually whether their graphics are being selected/deselected. I could not replicate the issue.

The Attribute window that you see from the EditorWidget and TemplatePicker, is our FeatureDataForm.  How the form looks like depends on the FeatureLayer.  What you define as OutFields in your FeatureLayer, will be the fields displayed on the form.   If your FeatureLayer comes from a MapService, then everything will be read-only.  If your FeatureLayer comes from an editable FeatureService, then whatever type or settings the service had given its fields will also apply to the fields in the form.  In other words, to ensure that your primary key field is not editable, you have to make that setting in the feature service. You can however, create your own attribute window and exclude the primary key field in your form so you can update this attribute with your default value. ... View more

Can you also share your code on how you define the  Editor?  Also, do you set the DataContext of your ClearSelection button?  In the XAML code I have, the StackPanel that includes my button has its DataContext set to the Editor.  Do you do something similar in your code-behind binding? ...

I was able to reproduce this when after clicking onto the second polygon to edit it, and then you double-click to the first polygon whose vertex was just deleted.  This bug will be fixed in the future release.  It will be avoided by ensuring that there can never be more than one feature for edit at one time. Thanks. ... View more

Renderer="{x:Null}" in XAML is equivalent to Renderer = null in code-behind. However during the layer's initialization process, if your feature service has defined its own renderer, and your renderer is null - which is true in this case because of Renderer="{x:Null}" in XAML - the default renderer defined by your feature service will overwrite your renderer.  This means, if you want FeatureSymbol to be used, you will need to set its renderer to null after the layer has initialized.  I suggest you do this Renderer = null after the layer has initialized. ...

I do not see anything wrong in the code you shared. It looks exactly like the sample, except Map was renamed. Check everywhere for GraphicsLayer, maybe it fails to retrieve the layer somewhere else not in this line.  Check the call stack, this usually tells you which code was executed before the NullReference exception. ...

If you are using SL, authentication is handled by your browser.  It is normal to see 401 on Fiddler, this just denotes that the service had required authentication and following this 401, must be a 200 with the results of your query, which means it passed the authentication process. Since you are using Fiddler already, you can look at the webrequests made by your SL app. You can make the same requests outside your SL app by going directly to the browser and sending the same parameters.  You can look at this thread, post #14http://forums.arcgis.com/threads/14730-Area-And-Perimeter for reference. While testing outside SL app, notice that there is 401 on Fiddler. ... View more
