Example

This example demonstrates how to allow users to search for a specific place on a map using the Search panel.

To enable searching in the map control, do the following.

• Create an InformationLayer and add it to the map.
• Create an instance of the BingSearchDataProvider and assign it to the InformationLayer.DataProvider property.
• Specify the Bing Maps key using the BingMapDataProvider.BingKey property.

The Search panel appears automatically (since the BingSearchDataProvider.ShowSearchPanel property value is true by default).

Note

Refer to How to: Get a Bing Maps Key if you run the application and see a window with the following error message: “The specified Bing Maps key is invalid. To create a developer account, refer to https://www.microsoft.com/en-us/maps/create-a-bing-maps-key“.
