GridView - Master / Detail expand button is not displayed

Hello Rico,

Thank you for contacting us. Would you please describe the issue you have encountered in greater detail?
- What does the issue look like? If possible, make a detailed screencast that illustrates how to reproduce this issue from scratch. For example, use the Jing tool for this purpose;
- If this issue is browser-specific, specify the browser family/version:
    - Detailed information about the browser: make a screenshot of the "Help -> About ..." dialog;
    - Browser/Document mode settings - press the F12 key to invoke the Dev Toolbar (for the IE browser only);
- Provide us with a simple working project that illustrates the issue in action. With a small example project, it is much easier for us to verify that the code that calls ours is valid, and that the way our controls are being used is recommended. This way, we can concentrate our resources on the problematic area:

Your time and cooperation are greatly appreciated.
