Gray-out the text on the tab control display?

[KMiller]

I would like to control entry into one or more of the tabs

I have set up on my Tab control based on set rules. Does
anyone know how to grey-out the text so that a user will
see that they do not have access to that particular tab?

I tried setting the enabled = false for the given tab, but it only seems to work in the form assembly section (that
is, if I do it after the form is loaded through a
function, it doesn't seem to work), and doing that
disables the controls on the tab, but does not grey out
the text of the tab display itself.

Thanks

I assume you don't know before loading the form which to enable/disable? If
so a contructor passed a tabindex would work fine.

I also assume that you have tried setting the enabled property for the
particular tab page that you want disabled...

Is this true?

Hi K,

wow, I see your point.

I thought I had it fixed in my app too but my titles aren't disabled either.

You can do ownerdrawn fixed and change the color of the font easy enough.

Private Sub TabControl1_Dra wItem(ByVal sender As Object, ByVal e As
System.Windows. Forms.DrawItemE ventArgs) Handles TabControl1.Dra wItem
Dim tp As TabPage
Dim layoutrct As New RectangleF(e.Bo unds.Left, e.Bounds.Top,
e.Bounds.Width, e.Bounds.Height )
Dim sf As New StringFormat(St ringFormatFlags .FitBlackBox)
sf.Alignment = StringAlignment .Center
sf.LineAlignmen t = StringAlignment .Center

tp = TabControl1.Tab Pages(e.Index)
If Not tp.Enabled Then
'for some reason not printing the 3-d part--tried to print twice
with offset but no luck
e.Graphics.Draw String(tp.Text, e.Font, SystemBrushes.C ontrolLight,
layoutrct)
layoutrct.Offse t(2, 2)
e.Graphics.Draw String(tp.Text, e.Font, SystemBrushes.C ontrolDark,
layoutrct) 'SolidBrush(e.B ackColor), layoutrct)
Else
e.Graphics.Draw String(tp.Text, e.Font,New SolidBrush(e.Ba ckColor),
layoutrct)
End If
End Sub

This works if items are not enabled. But there must be an easier way--also
they shouldn't even be able to click on the tab.

I haven't found out how to avoid that.

this is a really big pain for something simple--but it seems that most of
the control included are lacking in very bacic features and require lots of
extra coding to just do standard things.

I hope you find an answer--I would also like to know.

You'll have to OwnerDraw the Tabs if that's the appearance you want.
Why not simply remove the Tabpages that the user has no access to?

Mick,

I told her the same thing, but how do you draw them with the normal 3d
enabled look?

I tried drawstring using a layout rect and then offset(1,1) or offset(2,2)
on it and drew again using the same with a different color but it doesn't
work.

Also,
disabled means you shouldn't even be able to select the tab in the first
place. How can this be accomplished?

Thanks,

Shane

Thanks for the responses to all..

Seems like a lot of trouble to execute a very simple
change. We purchases the Infragistics UltraDev suite a
while back, which includes a tab control, but we had not
been using it. I just checked it out and sure enough, it
grays-out the text by simply disabling the tab. I may
just swap out by MS tab for this one.

Your reply was close. Use ControlPaint.Dr awStringDisable d() not
Graphics.DrawSt ring() twice.
As for not being able to select Disabled Tabpages, that can be emulated,
although I feel it is better to remove the TabPage than display it as
Disabled.

Code follows:

\\\
Private ValidPageIndex As Integer = 0

Private Sub TabControl1_Dra wItem(ByVal sender As Object, _
ByVal e As System.Windows. Forms.DrawItemE ventArgs) _
Handles TabControl1.Dra wItem

Dim CurrentTabPage As TabPage = TabControl1.Tab Pages(e.Index)
Dim r As RectangleF = RectangleF.op_I mplicit(e.Bound s)
Dim ItemBrush As New SolidBrush(TabC ontrol1.BackCol or)
Dim TextBrush As New SolidBrush(TabC ontrol1.ForeCol or)
Dim sf As New StringFormat

sf.Alignment = StringAlignment .Center
sf.LineAlignmen t = StringAlignment .Center

e.Graphics.Fill Rectangle(ItemB rush, e.Bounds)

If CurrentTabPage. Enabled = False Then
ControlPaint.Dr awStringDisable d(e.Graphics, _
CurrentTabPage. Text, _
e.Font, _
ItemBrush.Color , _
r, sf)
Else
e.Graphics.Draw String(CurrentT abPage.Text, _

End If

End Sub

Private Sub TabControl1_Sel ectedIndexChang ed(ByVal sender As Object, _

TabControl1.Sel ectedIndex = ValidPageIndex
Else

End If
End Sub

cool, never have noticed that method.

This should have been implemented in the control to begin with.

That or you could try to make your own control inheriting from the tab
control, "K's Tab Control"

Just add that functionality and display some interface for disabling
tabs....

You're right it's a pain and like most things I've found in .net, is a
standard expectation that should have been implemented in the original
control. (guess they want to make sure you go with 3rd part vendors and not
put them out of business or something.) Still there is lots of room for 3rd
party controls and I agree with you that things like this are just bare
minimum expected behaviors.

Removing the tab does seem to be a lot easier. I suggest that route unless
you want to make your own reusuable control--which shouldn't be too hard....
;) maybe.
