Desable a TabControl Page...

[AlexCode]

As the Framework controls shows us every single day... they suck!

And the TabControl its another good example of that!

 

Is it asking too much to want to desable a TabPage?

 

Is there a way I can achieve this goal?

 

Thanks!

 

Alex :(

Maybe this ??

 

TabPage1.enabled = False

[AlexCode]

:P Certainlly isn't that! Too Easy! :D

 

I want to desable the Tab itself, and desableling lake you told, it only desables the objects on the tab but still allows the user to select that tab...

 

Got it?

 

Alex :D

[feurich]

Sorry For that :-)

 

I knew it was to easy, with a track record of 434 I should have known.

But maybe you can look at the following website:

And search for tabpages

 

It isn't exact what you need but maybe you can derive some answers from it.

[AlexCode]

Ok, I've seen it but I quite don't understand what it is... in fact I don't even know what program opens an *.AEF file...

 

Opening it with NotePad I saw that it's C++ code, but also it's a 1999/2000 code... not that stuff we can apply on a .net TabControl, or at least I can't... my C++ skills are worse than u can imagine! :D

 

Thaks anyway... I'll keep looking for somethig as I think this is an important issue to overcome...

 

Thanks

Could you not remove the tabpage in question instead of disabling it? I've had to do it that way myself before now, annoying that even visible = false doesn't work on a tabpage either.

[AlexCode]

Yeah... that visible issue sucks just like the complete TabControl do...

 

Latelly I've used the Magic TabControl... it seemed to work fine and had all theese issues working like a charm and plus, on thet time, it was free!

But time and experience told me that it has other bug... if sometimes break the databindings of the contained objects.

 

Now this problem:

Right now, I've the tabs removed like you said but I think its more clear to the user, in this case, he can see what he have and what he don't have if the tabs were there but desabled...

 

The most strange thing is that I can't find so many people asking for this as I expected when I started searching on Google...

 

I'll keep trying...

Thanks.

Could you not use a wizard style, with a previous and next button and a point by point guide to let the user now how far they have progressed?

 

Divil has quite a nice wizard component on his web site http://www.divil.co.uk/net/controls/wizardcontrol/ that is pretty easy to use.

Why dont you just check if the user is tying to change to that tab, and just move them back to the old one ?

[AlexCode]

That could be an option but the Tab itself wouldn't be shaded...

 

I'v found a way to work this out. Possibli I'll make an IExpandableProperty to add this functionallity to the tab controls...

 

It still needs some work but it's a start...

 

   Dim CurrentIndex As Integer = -1
   Dim TPs As New ArrayList
   Structure stTPs
       Dim TP As TabPage
       Dim Enabled As Boolean
   End Structure

   Private Sub TabControl1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TabControl1.MouseMove
       Me.TextBox1.Text = e.X & ";" & e.Y
   End Sub

   Private Sub TabControl1_ControlAdded(ByVal sender As Object, ByVal e As System.Windows.Forms.ControlEventArgs) Handles TabControl1.ControlAdded
       Dim TP As New stTPs
       TP.TP = e.Control
       If Me.TabControl1.TabPages.Count > 2 Then
           TP.Enabled = False
       Else
           TP.Enabled = True
       End If

       TPs.Add(TP)

   End Sub

   Private Sub TabControl1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabControl1.SelectedIndexChanged
       For Each TPage As stTPs In TPs
           If TPage.TP Is Me.TabControl1.SelectedTab Then
               If TPage.Enabled Then
                   CurrentIndex = Me.TabControl1.SelectedIndex
               Else
                   Me.TabControl1.SelectedIndex = CurrentIndex
               End If
               Exit Sub
           End If
       Next
   End Sub

   Private Sub TabControl1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem

       For Each TP As stTPs In TPs
           If TP.TP Is Me.TabControl1.TabPages(e.Index) Then
               If TP.Enabled Then
                   e.Graphics.DrawString(Me.TabControl1.TabPages(e.Index).Text, Me.Font, System.Drawing.Brushes.Black, 4 + (62 * e.Index), 4)
               Else
                   e.Graphics.DrawString(Me.TabControl1.TabPages(e.Index).Text, Me.Font, System.Drawing.Brushes.Gray, 4 + (62 * e.Index), 4)
               End If
           End If
       Next

   End Sub

   Private Sub TabControl1_ControlRemoved(ByVal sender As Object, ByVal e As System.Windows.Forms.ControlEventArgs) Handles TabControl1.ControlRemoved

   End Sub

   Private Sub TabControl1_TabIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabControl1.TabIndexChanged
       CurrentIndex = Me.TabControl1.SelectedIndex
   End Sub
