You can create your own custom fields and add them to the Report Designer palette. To do that, you have to:

1. Create a custom field class that derives from C1.C1Report.Field.
2. Register your custom field assembly in C1ReportDesigner.exe.settings.

For registering a custom field, say MyField, add your control to the <customfields> section in the C1ReportDesigner.exe.settings file as follows:

<customfields>
<!-- THIS LINE ADDS A NEW FIELD TO THE DESIGNER -->
<item value="MyCustomFieldAssembly;MyCustomFieldAssembly.MyField" />
</customfields>

Note that the code above assumes that your field is called "MyField" and it can be found in the assembly called "MyCustomFieldAssembly".

Following are built-in standard custom fields that are loaded in the C1ReportDesigner application by default:

• Chart
• Gradient
• SuperLabel
• QRCode
• Map
