The CustomTileProvider sample demonstrates how to create a custom tile provider using IMapTileProvider and IMapTile interface and configure it in a Map Control which is placed on a RDL report. This sample makes use of two projects - CustomTileProviders and TileProviderEndUserDesigner in a single Visual Studio solution. The CustomTileProviders project contains the tile server configurations for the tile providers, whereas the TileProviderEndUserDesigner project references the created CustomTileProviders project assemblies.

Note: CustomTileProvider is for use with the Professional Edition license only. An evaluation message is rendered when used with the Standard Edition license.

Run-Time Features

When you run this sample, the ActiveReports End User Designer appears with an overlaying Help-Creating a Custom Tile Provider dialog. This dialog gives you step-by-step instructions to create a new tile provider for a Map control with custom settings.
The End User Designer displays a RDL report containing a Map control with MapQuest set as the default tile provider. To change the existing tile provider, double-click on the Map control to display the existing tile layer and right click to select Edit. In the Map Tile Properties - General dialog that appears, click the Provider drop-down to select the tile provider you want to apply to the Map control. Go to the Preview tab to view the data in the selected tile provider. You can choose from the following tile provider options:
Note: The Microsoft Bing Map server offers static map images. This requires an Application key for authentication. The default key provided by ActiveReports is for demo purpose and can not be used by 3rd party applications. In order to obtain a Bing Map Key, see HowTo - Create a Bing Map Account and HowTo - Generate a Bing Map Key.

This folder contain files that are used in the CustomTileProvider project.

CloudMadeTileProvider.cs

This class implements the IMapTileProvider interface and contains the settings for the map tile images provided from http://cloudmade.com.

GoogleMapsTileProvider.cs

This class implements the IMapTileProvider interface and contains the settings for the map tile images provided from http://maps.google.com.

MapQuestTileProvider.cs

This class implements the IMapTileProvider interface and contains the settings for the map tile images provided from http://www.mapquest.com.

MapTile.cs

OpenStreetMapTileProvider.cs

This class implements the IMapTileProvider interface and contains the settings for the map tile images provided from http://www.openstreetmap.org.

WebRequestHelper.cs

This class picks the raw data from the tile providers and loads them into the System.IO.MemoryStream class.

TileProviderEndUserDesigner folder

This folder contain files that are used in the TileProviderEndUserDesigner project.

CustomTileProvider.rdlx

This report contains the Map control that visualizes the oil production in different parts of the world on a virtual earth background. The map control uses the color rule set on a polygon layer to differentiate parts of world as per their oil production capacity. These colors are defined using a color rule which is described in the legend at run time. The report gets the data from Factbook.rdsx shared data source. 

DesignerForm.cs

This is the main form that gets displayed when you run the sample. This form uses multiple controls like the ToolStripPanel, ToolStripContainerPanel, SplitContainer, Designer, Toolbox, ReportExplorer and PropertyGrid controls to create a customized End User Designer. It also contains code to load CustomTileProvider.rdlx report into the Designer.

GrapeCity.ActiveReports.config

This configuration file contains the settings for the various tile providers, and is located in the same folder as the EndUserDesigner.exe file for the tile provider settings to work.

HelperForm.cs

This form uses the HelperForm class to display a screen containing step-by-step instructions for the user to create a custom tile provider.
