Reports for WinForms supports map fields using its extensible custom field architecture. The Map custom field is implemented as a custom field in two using two assemblies from ComponentOne Studio WPF Edition: C1.WPF and C1.WPF.Maps, which are installed with the report designer application. In the following topics, you'll see how you can customize map fields in reports using the C1ReportDesigner application.

Note that the Map custom field uses two assemblies from ComponentOne Studio WPF Edition: C1.WPF and C1.WPF.Maps. Make sure that these assemblies are available and referenced by your project before you begin.

To start using the Map custom field in the C1ReportDesigner application, complete the following steps:

1. Run the C1ReportDesigner application. See Accessing C1ReportDesigner from Visual Studio for details.
2. Confirm that the map icon is present in the C1ReportDesigner toolbar. If it is not included, you may need to add the following line to the <customfields> section of the C1ReportDesigner.EXE.settings file: <item value="C1.C1Report.CustomFields.4;C1.C1Report.CustomFields.Map" />
3. Create a new report or open an existing report. See Step 1 of 4: Creating a Report Definition for an example.
4. Click the map icon and drag it onto your report to add a Map field.

That's it! The main aspects of the Map field include:

• tile and data layers
• legends
• styles
• expressions
• auto zooming/centering and data tracking
