Is there anybody know how to create a closed multipatch ? I create two cubes which I believe they are enclosed. but the ArcGIS 3D analyst told me it is not. I wondered if there is any criteria which should be used to create the closed cube . Please help ! the final result I need is to extract the overlapping part of the two cubes, In order to do this, the cubes have to be closed.

Hello everyone, I am trying to change the sample codes to run time labeling function, which needs to enable labels to show when you click a button ArcGIS API for Silverlight - Interactive Samples | ArcGIS for Developers ---this is the sample I was trying to modify. and the result I got from step-by-step debugging looks fine. but I don't see any labels show up to my map here are my codes: private void Button_Click(object sender, RoutedEventArgs e) { ArcGISDynamicMapServiceLayer DLayer = new ArcGISDynamicMapServiceLayer(); DLayer = (ArcGISDynamicMapServiceLayer)MyMap.Layers["PDLayer"]; DLayer.LayerDrawingOptions = new LayerDrawingOptionsCollection(); LayerDrawingOptions layerdrawingoptions = new LayerDrawingOptions() { LayerID = 1, ShowLabels = true, ScaleSymbols = true }; LabelClassCollection labelclasscollection = new LabelClassCollection(); LabelClass labelclass1 = new LabelClass() { LabelExpression = "[POP2000]", LabelPlacement = LabelPlacement.LinePlacementAboveAfter, Where = "[POP2000] <= 61", MinScale = 5000, LabelOptions = new LabelOptions() { Color = Colors.Red, FontFamily = new FontFamily("Arial"), FontSize = 10, FontWeight = FontWeights.Bold } }; LabelClass labelclass2 = new LabelClass() { LabelExpression = "[POP2000]", LabelPlacement = LabelPlacement.LinePlacementAboveAfter, Where = "[POP2000] > 61 AND [POP2000] <264", MinScale = 15000, LabelOptions = new LabelOptions() { Color = Colors.Black, FontFamily = new FontFamily("Arial"), FontSize = 10, FontWeight = FontWeights.Bold } }; LabelClass labelclass3 = new LabelClass() { LabelExpression = "[POP2000]", LabelPlacement = LabelPlacement.LinePlacementAboveAfter, Where = "[POP2000] > 264", MinScale = 30000, LabelOptions = new LabelOptions() { Color = Colors.Blue, FontFamily = new FontFamily("Arial"), FontSize = 14, FontWeight = FontWeights.Bold } }; labelclasscollection.Add(labelclass1); labelclasscollection.Add(labelclass2); //=labeldrawingoptions.labelclass.add() labelclasscollection.Add(labelclass3); layerdrawingoptions.LabelClasses = labelclasscollection; DLayer.LayerDrawingOptions.Add(layerdrawingoptions); DLayer.Refresh(); MyMap.UpdateLayout(); }

Problem fixed: Solution. I was setting the extent at the runtime, which caused the above problem. So I set the extent in XAML file to let it run in the design time. the problem is gone.

hello, I reviewed my code. here is my solution to figure out the problem. I didn't use generic.xaml. but I put all the merge directory in the app.xaml. and I add the x:Key in the window panel style . here is my codes look like: <Style x:Key="Windowpanel"> <Setter Property="Effect" Value="{StaticResource dropShadow}" /> <Setter Property="HorizontalContentAlignment" Value="Stretch" /> <Setter Property="VerticalContentAlignment" Value="Stretch" /> <Setter Property="Background" Value="{StaticResource CommonBackgroundBrush}" /> </Style> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/dms_geo;component/Map/Arc/Styles/NavigationStyle.xaml" /> <ResourceDictionary Source="/dms_geo;component/Map/Arc/UserControls/WindowPanel.xaml" /> <ResourceDictionary Source="/dms_geo;component/Map/Arc/UserControls/CollapsiblePanel.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> Application>
