QUESTION
Can the license be used in the testing/development environment?
ANSWER
The server and WinForms license may be used to test/develop applications; however, the website license requires that the registered domain name appear in the browser address text box. This will limit the website license from being used in development/testing.
A property under the chart object: Chart.OverlapFooter may be set to true in order to make the charts render in the exact size as they will appear in productions when the branding is removed to ensure proper testing.
