Bizzare ViewState issue (ASP.NET)

Hello there,

I've created UserControl which is used as a menu. It is populated dynamically and has two levels.

The weird thing is though that second level controls' click event is fired but it the code executed in it seems to have no effect at all:



public void SubCourseRoundMenuClick(object a, CommandEventArgs e)
{
pnlCourseEvents.Visible = false;
pnlCourseSubEvents.Style["display"] = "block";
}

Both properties changes to their old values when observed in any event fired after SubCourseRoundMenuClick.

All menu items and subitems are populated at the same order on every postback. EnableViewState=false on UserControl (though i've tried other way round as well).

For suspect ViewState is playing tricks on me.

This issue is really driving me bonkers so any advice or guidance would be much appreciated.

Best Regards,

Dave
