url map services

AgatinoLa_Rosa — Mon, 26 Jul 2010 15:54:10 GMT

I have a map with three layers defined as below.

<esri:Map Name="baseMap">
<esri:ArcGISTiledMapServiceLayer ID="BaseLayer" Url="http://worldmap/MapServer"/>
<esri:ArcGISDynamicMapServiceLayer ID="SelectedService" />
<esri:GraphicsLayer ID="myGraphics" />
</esri:Map>

The dynamic service URL is defined in the c# code according to users' selection. The graphics are also added dynamically using the code.

I can clear the graphics in the graphiclayer, how can I clear the dynamic map service before reassigning a new url or should I redraw the whole map. Any suggestion to improve caching problems with many services to be visualized. Thanks.

In my opinion, you have only to reassign the url.

It is working now I am not sure what could be wrong. Thanks anyway.
One more question. The zoom functionality is working using the wheel, I don't get the pan working using the mouse. Any idea?

This can happen if your map is inside a scroll viewer. Is it your case?

sorry for the late reply. Yes, I have also seen another case in the forum and the scrollview is the cause. However I have added a navigator on the map so somehow I solved the problem.

Thanks

When I started this thread I had three layers. Now users can select either a cached or dynamic layer from a list of Layers. So either one between SelectedDynamicService or SelectedCachedService would be displayed.

<esri:Map Name="baseMap">
<esri:ArcGISTiledMapServiceLayer ID="BaseLayer" Url="http://worldmap/MapServer"/>
<esri:ArcGISDynamicMapServiceLayer ID="SelectedDynamicService" />
<esri:ArcGISTiledMapServiceLayer ID="SelectedCachedService" />
<esri:GraphicsLayer ID="myGraphics" />
</esri:Map>

If I set the map layers as above I get problems at run time when either one url is not assigned. Is there a way I can set a generic Layer at design time and then assign a dynamic or cached url at run time?

No way to define a generic layer at desin time.

You might consider to create the layer by code after the user selection.
