Scroll Bar does not appear for TabPage.

Hi,

While trying to convert an ERP from VWG to Wisej, I have encountered this problem:

The Scroll Bar of TabPage control does not appear even the contained controls are out of the boundary of the TabPage. For example, I set the size of the TabControl to 200 X 200. I add an Panel to a TabPage of this TabControl, and set the size of this panel to 800 x 800 (refer to the image attached).

In the Designer, the scroll bar appear as expected. But at run time, the scroll bar cannot be shown.

Regards,

Felix CHAN
