Infragistics UltraTabControl - Problem changing the selected tab.

Posted on 2010-11-30
Last Modified: 2012-05-10
I'm using an Infragistics UltraTabControl version (Infragistics2.Win.UltraWinTabControl.v8.3.dll)

In my code depending on a certain data criteria I try to change the tab being displayed, with the following line of code.
Me.utcTemplatesAndWorkings.SelectedTab = Me.utcTemplatesAndWorkings.Tabs("tabBudgetSummary")

Nothing happens the tab does not change?

Any ideas.

I tried the code by adding a tab control on a form with 10 tabs.
In a button click event I call:
Me.UltraTabControl1.Tabs(9).Selected = True
and the tab scrolls into view and becomes active.

Where in your code do you make the tab active (which event)?

Hi I tried the calling my code from a button click event and it worked.
The scenario that does not work is if I call the SelectedTab or Selected = True from the validated event on a combo box.

The selectedtab code is definately being hit i put a break point on it. The breakpoint only get hit once so it is not in some sort of crazy loop either.

Try calling the Application.DoEvents or Refresh method of the tabcontrol.

I added a brand new tab control to the same region on the form with nothing on it just two tabs.
Same result.

Strangely I'm still able to disable tabs.

Here is a workaround.  Not pretty, but it works.
1) disable the active tab
2) select a different tab
3) re-enable the previous active tab

        Dim activetab As Integer = UltraTabControl1.ActiveTab.Index
        UltraTabControl1.Tabs(activetab).Enabled = False
        UltraTabControl1.Tabs(2).Selected = True
        UltraTabControl1.Tabs(activetab).Enabled = True

Thanks For the suggestions.

A colleague of mine solved the problem using a delegate.
When you want to change the tab you invoke the delegate and in there you change the tab.

Don't ask me why this works but it does.

You never mentioned you are using threads or timer or backgroundworker etc!

If you want to make the tabs invisble you should also use a delegate if you have a similar problem.
