layers

ThaoNguyen

Hi experts,
I have 2 layers in my map as follow:
<esri:Map x:Name="TestMap" Extent="-130,10,-70,60" Width="700" Height="500"
                  MouseRightButtonDown="TestMap_MouseRightButtonDown"                  
                  Grid.Row="0" Grid.RowSpan="2" Grid.Column="0"
                  VerticalAlignment="Top"> 
       <esri:Map.Layers>
                <esri:ArcGISDynamicMapServiceLayer ID="BigMap"
                    Url="http://xyz/ArcGIS/rest/services/MyMap/MapServer" />
                   
                <!-- graphic map  -->
                <esri:GraphicsLayer ID="ResultMap"
                                    MouseLeftButtonDown="annotations_MouseLeftButtonDown"
                                    MouseEnter="GraphicsLayer_MouseEnter"
                                    MouseLeave="GraphicsLayer_MouseLeave">
                </esri:GraphicsLayer>
       </esri:Map.Layers>
</esri:Map>

Question 1:
Whenever I select an area (e.g a region or group of states), the graphic layer will paint that area with a color (it is like the spatial query sample provided by ArcGIS).  Since the graphic layer is on top of the "BigMap" layer, the BigMap layer looks vague under the selected area (you can see that in the sample version as well).  Is there a way I can make both layers look clear? 

Question 2:
If I change to Pan mode, I cannot drag the map when the cursor is on top of the painted area.  In my code, when a tool bar icon is clicked, I also enable/disable a Draw instance.  Don't know if this is the cause of the problem.  The spatial query doesn't have this problem and it doesn't enable/disable Draw instance.


Thanks so much!

Actually, when the map is first launched, there is no tool activated, I still cannot drag the map when the cursor is on the graphics layer.  Draw.IsEnabled = false, draw mode is None.  What else do you think may cause the problem?  When my Pan icon is clicked, I disable the draw and change draw mode to none as well.  I guess something else causes the problem, but can't figure out what.

I found out why I could not drag.  In the event handler method for MouseLeave, I had the line
QueryDetailsDataGrid.Focus(); which focus the data grid.  After I removed this line, the drag problem was resolved.  Don't know why.
