TabControl Question... 4

[pzmgmb]

I know i can do this in VB .NET with the TabControl:

Me.TabControl1.TabPages(0).Enabled=False

Why can't i do this?

Me.TabControl1.TabPages("Inventory").Enabled=False

Could anybody help me to achieve this?

Hmmm, interesting one - it appears a tabcontrol page does not have an enabled property and therefore you could not possible perform this task. However, I'm sure there must be a way to do it knowing the complexity and functionality of .net - just haven't found it yet !!!!

OK, this doesn't really help, so as an interim 'get round', why not programatically hide and unhide the tabpage -


eg

If condition = True Then
me.TabControl1.TabPages.Remove(TabPage1)
else
me.TabControl1.TabPages.Add(TabPage1)
End If


Removing and adding a tabcontrol page does not affect the controls on the page itself.


Hope this helps,
Paul

TabPages only accepts an integer index so to get around it you could use the following method

Private Function GetTabPage(ByVal Name As String) As TabPage
        Dim page As TabPage
        For Each page In TabControl1.TabPages
            If page.Name = Name Then
                GetTabPage = page
                Exit Function
            End If
        Next
    End Function

To call it ...

GetTabPage("TabPage1").Enabled = False

Haven't tried your code, but if it works, good on ya!!

Just for your info, the code I posted will accept the tab page name and not just the array/integer reference

jubble,
Thanks for the code... good idea... i just thought there would be a more eloquent way in .NET. Guess Not.

 

[jubble]

You're right .... there should be one tucked away somewhere but I haven't found it yet.
Sometimes there are some methods and properties that don't show up in intellisense so it's worth trying the name of a method or different parameter types just to see if it hasn't been exposed properly.

If you're using visual studio .Net 2k2 do the following:

Tools -> Options -> Text Editor -> Basic -> General

Uncheck the "Hide Advanced Members" check box.

Nice one!

Thanks for the tip.

You mentioned 2k2...it's also checked by default in 2k3.

 

[ThatRickGuy]

hmm, I had heard that the patch for 2k3 unchecks it.

patch?!

I'm getting so bloody concerned with networking patches that I totally missed that one.

Was it provided with MSDN?

 

[jubble]

I've still missed it ... there seems to be very little info regarding a VS.Net 2003 Patch/Service Pack.

 

[ThatRickGuy]

I must of heard wrong. After a quick look all I could find was a security update:

http://www.microsoft.com/downloads/...0e-808d-431d-a7d3-33bc3ace922d&displaylang=en

no service packs or patches

Have a

from me Rick as that has been bugging me for ages (there is a IsStartupScriptRegistered method in ASP.NET that I could use but it never appeared as intellisense and I couldn't figure out why!)

Thanks again
Mark
