Hi Mirek,
Thank you for your question.
The
AutoSize property comes from the base
Control class, but is not relevant for all controls.
RadSplitContainer is one of the controls that does not support
AutoSize. Furthermore, when you set the
Dock property of
RadSplitContainer to
Fill, it always occupies the entire client area of its parent (the
RadPageViewPage) and therefore cannot be sized. On the other hand, the
SplitPanels are arranged internally by the
RadSplitContainer and also cannot be sized.
To achieve the desired scenario, you can implement the automatic sizing by handling some events. This is demonstrated in the attached files.
I hope this will help you. Do not hesitate to ask if you have any additional questions.
Regards,
