I have a tab control in a C# app and I'm trying to hide and show tabs based off of various user selections off of combo boxes, etc. 

The problem is I have 8 tabs.  I hide/show all the tabs in one routine.  For some reason I am having controls from a tab that should be hidden, show up on one of the visible tabs.  I'm not sure what the problem would be.  Here is the code I am using.

myUltraTab.Tabs["tab1"].Visible = true;
myUltraTab.Tabs["tab2"].Visible = false;
myUltraTab.Tabs["tab3"].Visible = false;
myUltraTab.Tabs["tab4"].Visible = true;
myUltraTab.Tabs["tab5"].Visible = false;
myUltraTab.Tabs["tab6"].Visible = true;
myUltraTab.Tabs["tab7"].Visible = true;
myUltraTab.Tabs["tab8"].Visible = false;
