Hi Mr Santos!
Thanks for definition, I created an application based on your steps, but problem is not reproduced. What VWG version do you use? I tried to reproduced this bug on current v.6.4 Beta1b in VS2008 and 2005.
You may sent sample application, that would reproduce your problem to Support [at] VisualWebGui [dot] com with a link to this forum thread.
Please also clean the solution before compressing it and reply to this post after sending, with the subject of the e-mail you send, so I would know to check for your support request.
Regards,
