I'd like to be able to suspend zooming and panning on-demand. In other words, have a toggle button or any other control that would enable/disable the zooming and panning. Is that possible? Are there any properties for this I can use? Examples?? Thanks! ... View more

I have a map with a specific layer that I want my users to be able to reset the extent to. So I basically added a little button that on the click event has this: GraphicsLayer l = (GraphicsLayer)this.map1.Layers["MY_LAYER_ID"];                                 this.map1.Extent = l.FullExtent; That works fine as long as the window is Maximized. If the window that holds the map is in any other size then it only shows whatever part of the viewing area is shown at that moment. What I'd like to happen is that the map resets to the extent the layer has but that the layer in question if shown entirely in the current viewing area. Is there an example of that somewhere? How can I accomplish this? Thanks! ... View more

Let me start by explaining my business issue. I have two Graphics layer on a map, one of them has the graphics I want to show, the other one has TextSymbol as symbols and shows as a label of the graphics in the first layer (see the attachment for clarification). So, now let's say the user turns off the graphics layer, then the "labels layer" will still be turned on, so that looks awkward. So basically I would like the "labels layer" to be turned off in the same event when the graphics are turned off.  Ok, so here is the technical stuff. I have a Legend added to my map where the users can turn the layers on and off: <esri:Legend Name="legend1" Map="{Binding ElementName=map1}" LayerItemsMode="Tree" ShowOnlyVisibleLayers="False" FontSize="11" Refreshed="legend1_Refreshed">                 <esri:Legend.MapLayerTemplate>                     <DataTemplate>                         <StackPanel Orientation="Horizontal">                             <CheckBox Content="{Binding Label}"                   IsChecked="{Binding IsEnabled, Mode=TwoWay}"                   IsEnabled="{Binding IsInScaleRange}">                             </CheckBox>                             <Slider Maximum="1" Value="{Binding Layer.Opacity, Mode=TwoWay}" Width="50" />                         </StackPanel>                     </DataTemplate>                 </esri:Legend.MapLayerTemplate>                 <esri:Legend.LayerTemplate>                     <DataTemplate>                         <CheckBox Content="{Binding Label}"                    IsChecked="{Binding IsEnabled, Mode=TwoWay}"                 IsEnabled="{Binding IsInScaleRange}" >                         </CheckBox>                      </DataTemplate>                 </esri:Legend.LayerTemplate>              </esri:Legend> So, this is what I need help with. What I'd like to do is capture the event that turns the layers on and off. I guess that would be for the CheckBox?? Or can I capture it in the layer per se?? So, say that I extend the layer and interesect the event there?? Thanks! ... View more

I have a GraphicsLayer where I add several TextSymbols. I'd like to be able to have a List of TextSymbols returned by my layer, so I extended the GraphicsLayer class  and just added a simple function that retrieves the Graphics and cast them into TextSymbols. All good so far until I tried it. Here is the code: public List<TextSymbol> TextSymbolList(){                           List<TextSymbol> l = new List<TextSymbol>();             foreach (Graphic g in this.Graphics)             {                 l.Add((TextSymbol)g); //THIS DOES NOT WORK             }                          return l;         } So, my question is, how is it that I can add the TextSymbol object to the Graphics list but I cannot retrieve it or cast it back to TextSymbol? How can I accomplish this or something similar? Any suggestions? Thanks! ... View more

I have a GraphicsLayer where I show some TextSymbol's. They are place in position and show correctly. The problem is that they are geographically close and the different texts for each position show up on the map like a mass of unreadable text until you zoom in and get close to them. So we thought that we may show the layer only after some position of the zoom. I have seen this effect in other layers but don't know how to create it. Any ideas? Thanks! ... View more
