Examples
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 MapControl.Layers collection.
- Create an instance of the BingSearchDataProvider and assign it to the InformationLayer.DataProvider property.
- Specify the Bing Maps key using the BingMapDataProviderBase.BingKey property.
The Search panel appears automatically (since the BingSearchDataProvider.ShowSearchPanel property value is true by default).
NOTE
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”, refer to the following tutorial: How to: Get a Bing Maps Key.
