Create a Reproducible Sample Project

As outlined in the DevExpress Support Services Policy, support engineers may ask you to create a sample project if/when an issue cannot be reproduced based on information submitted via the DevExpress Support Center. Your sample project should reproduce the issue reliably (the sample should not contain – or should minimize – unrelated business logic and components).

To create your sample project, you can use DevExpress Project Templates, demos, or examples as a starting point. Alternatively, you can follow the steps below to isolate the underlying issue in your project:

1. Find a small code snippet in your sample project. It can be a function, a template, or a part of a component.
2. Remove (comment out) the code and refactor it so that your project can be executed without errors. You can use IDE refactoring tools to simplify this process.
3. Check if the issue persists. If it does, this means that the code snippet in question was unrelated to the issue.
4. Repeat steps 1-3 until you cannot simplify your code further.
5. Make certain that the sample project can be compiled and executed after all modifications.

The purpose of the steps outlined above is to generate a sample project for further analysis by the DevExpress Support Team. Additionally, creating a sample project can offer unexpected insights as to underlying cause/source of issue, giving you the opportunity to address the matter using existing DevExpress technical resources (Knowledge Base and Documentation).
