Show progress bar to Thematic load

MichelleGonzalez — Wed, 16 Jan 2013 13:11:08 GMT

Hello,

I have developed a Silverlight Map Application that has a thematic button. It's base on the Atlas sample. The button works fine, but my problem is that I have a lot of data related to each thematic option and the load of the graphics on the map takes more time than the load of the legend. Because of this the users think that there was an error. I have managed to show a loading image in the legend's canvas, but of course when the legend loads it disappears and there are no graphics on the map. The graphics appear some 5 to 10 seconds later.
I want to show the map's progress bar while the new graphic layer is loading, but I can´t find a way to do so.

Is that possible??

Thanks for your help.

Michelle

<widget:ThematicMap x:Name="ThematicMap" Visibility="Collapsed">
            </widget:ThematicMap>

MainPage.cs : Added this references

            ThematicMap.SetParent(this);
            ThematicMap.SetMap(MyMap);
