Map is slow if assigning Bing provider

[DMC Helpdesk]

Hi,

I have been working on a project that uses RadMap with Bing provider for few months and everything seemed fine but recently I am seeing a delay of 13 seconds.The delay will not occur if I remove the code of provider assignment.

BingMapProvider provider = new BingMapProvider(MapMode.Road, false, "key");
radMap1.ZoomLevel = 12;
radMap1.Provider = provider;//delay will not occur if I remove this line
radMap1.Center = new Location(24.487987518310547, 54.483178253173828);

<telerik:RadMap Name="radMap1"  ZoomLevel="12" HorizontalAlignment="Stretch" Margin="0"  VerticalAlignment="Stretch"
            MouseDragMode="None" MouseClickMode="None"  MapMouseClick="radMap_MapMouseClick" MouseLeftButtonDown="radMap1_MouseLeftButtonDown" MouseLeftButtonUp="radMap1_MouseLeftButtonUp" MouseMove="radMap1_MouseMove"></telerik:RadMap>

Thanks

Hi,

We haven't received such complaints (that the Map is slow when assigning a Bing Provider). There should be a different reason for this. Please provide us more details on your current RadMap implementation. It will be best if you can send us a sample project where we can reproduce this.

Hi,

Thanks for the project attached. We have tried to reproduce the problem with slow loading application for a couple of seconds during initialization, but unsuccessfully. You may find a sample video attached with what we see on our side.
Could you try to create a sample solution which uses the open street map provider to check a time of initialization on your local environment?
If the initialization using the open street map provider is quick, then the frizzing can be a result of initializing of the Bing Maps imagery service. We use asynchronous request for it, but the code of WCF service client is generated by Visual Studio. So, we can't be sure completely that for example unstable internet connection can be the cause of this problem.

Kind regards,
