radgrid with hierarchy problem

Hi,

I created a usercontrol with a radgrid on it. The grid has 3 levels the first level works
as expected but the second level won't expand. When clicking the second expand button
it just collapses all levels.

When I put the usercontrol on a 'real' webform (one not created via Sitefinity but in the
same web application) it works as expected.

I've tried adding/removing AjaxManager settings (by code as this won't work when dropped on
a masterpage)

Any ideas?

Regards,

  Peter

Hi j8,

Thank you for using our services.

Currently we have a bug with ViewState which blocks the use of RadGrid on Sitefinity pages, unless you bind the grid using clientside logic. Unfortunately until we fix the bug you will not be able to use server side bound RadGrid on Sitefinity 4.0 pages.
