AccordionControl - ContentContainer not visible if Expanded set to true on Form_Load with AnimationType = None

created 9 years ago

As per the subject, setting the AnimationType = None and Element .Expanded = true on Form_Load doesn't show the ContentContainer as you'd expect.

Once loaded you can collapse and re -expand the group and see the ContentContainer.

Example attached.

        Hi,
        We've found a problem with AccordionControl after fixing several issues - AccordionControl - Elements disappear at the form startup when a non-empty ContentContainer is used. Now, the problems are fixed (and you can request a hotfix in that thread). However, it is necessary to wrap your code in the Form.Load event handler with the AccordionControl.BeginUpdate and EndUpdate methods. It is important since the control is invisible at the moment the Load event is raised.
