灰显选项卡控件显示屏上的文字？ [英] Gray-out the text on the tab control display?

问题描述

我想控制进入一个或多个选项卡

我已根据设置规则设置我的Tab控件。是否有人知道如何使文本变灰，以便用户看到他们无法访问该特定标签？

我尝试设置enabled = false对于给定的选项卡，
但它似乎只在表单汇编部分工作（
，如果我在表单通过
函数加载后执行，它不会似乎工作），并这样做
禁用选项卡上的控件，但不会灰显选项卡显示本身的文本。

谢谢

K

解决方案

我假设您在加载表单之前不知道启用/禁用？如果

这样一个构造函数通过tabindex会工作正常。


我也假设你已经尝试设置
$ b的启用属性$ b你想要禁用的特殊标签页...


这是真的吗？

在表格组装时，我不要知道。

嗨K，


哇，我明白你的意思了。


我以为我也把它固定在了我的应用程序中但我的头衔也没有被禁用。


你可以修复所有权，并且很容易改变字体的颜色。


Private Sub TabControl1_DrawItem（ByVal发送者作为对象，ByVal e As

System.Windows.Forms.DrawItemEventArgs）处理TabControl1.DrawItem

Dim tp As TabPage

Dim layoutrct As New RectangleF（e.Bounds.Left，e.Bounds.Top，

e.Bounds.Width，e.Bounds.Height）

Dim sf As New StringFormat（StringFormatFlags.FitBlackBox）

sf.Alignment = StringAlignment.Center

sf.LineAlignment = StringAlignment.Center


tp = TabControl1.TabPages（e.Index）

如果不是tp.Enabled然后

''由于某种原因没有打印3-d部分 - 试图打印两次

带偏移但没有运气

e.Graphics.DrawString（tp.Text，e.Font，SystemBrushes.ControlLight，

layoutrct）

layoutrct.Offset （2,2）

e.Graphics.DrawString（tp.Text，e.Font，SystemBrushes.ControlDark，

layoutrct）''SolidBrush（e.BackColor）， layoutrct）

Else

e.Graphics.DrawString（tp.Text，e.Font，New SolidBrush（e.BackColor），

layoutrct ）

结束如果

结束次级


如果未启用项目，则此方法有效。但必须有一个更简单的方法 - 也是

他们甚至不能点击选项卡。


我还没找到如何避免这种情况。


对于简单的事情来说这是一个非常大的痛苦 - 但似乎包含的控制中的大部分都缺乏bacic功能，需要大量的额外编码才能做标准的事情。


我希望你找到答案 - 我也想知道。

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

K

解决方案

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?

At the time the form is assembled, I DO NOT know.
However, shortly thereafter (during the loading process),
I DO know whether they have access or not to the
particular tab. It''s at this time when I''m attempting to
disable (gray-out) the tab text, but nothing works.

I''ve tried setting the enabled property to false for the
tab, but doing that does nothing to the tab text display,
and users have no way of knowing they DO NOT have access
to the tab other then by clicking into it and finding out
that nothing works because all the controls have been
disabled. Leaving the functionality this way is
inadequate and out of spec.

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_DrawItem(ByVal sender As Object, ByVal e As
System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem
Dim tp As TabPage
Dim layoutrct As New RectangleF(e.Bounds.Left, e.Bounds.Top,
e.Bounds.Width, e.Bounds.Height)
Dim sf As New StringFormat(StringFormatFlags.FitBlackBox)
sf.Alignment = StringAlignment.Center
sf.LineAlignment = StringAlignment.Center

tp = TabControl1.TabPages(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.DrawString(tp.Text, e.Font, SystemBrushes.ControlLight,
layoutrct)
layoutrct.Offset(2, 2)
e.Graphics.DrawString(tp.Text, e.Font, SystemBrushes.ControlDark,
layoutrct) ''SolidBrush(e.BackColor), layoutrct)
Else
e.Graphics.DrawString(tp.Text, e.Font,New SolidBrush(e.BackColor),
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.
