Related API Members

The following members return BingSearchOptions objects:

• BingSearchDataProvider.SearchOptions

Remarks

Bing Search options are represented by the BingSearchOptions object that can be accessed via the BingSearchDataProvider.SearchOptions property.

Then, you can specify the search radius (BingSearchOptions.SearchRadius), the displayed number of search results (BingSearchOptions.ResultsCount) and other search parameters.

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“.
