I have a text box that when it is disabled the text in it is gray and kind of dithered. (This is the standard functionality.)
Is there a way to make this easier to see?
I have tried this:
txtBoxNumber.Enabled = false;
txtBoxNumber.ForeColor = Color.Black;
and that has no effect.
NOTE: This is a .net Compact Framework app, but I am not tagging the question with CF because I think it is the same for normal .net.
txtBoxNumber.ReadOnly = true;
// Then set your styles here...
HTH.
Why don't you make the TextBox.ReadOnly instead? That would allow the user to see & copy the textbox value, but not change it. A read-only textbox is usually rendered the same way as a normal textbox.
From MSDN:
You can use this feature instead of disabling the control with the Enabled property to allow the contents to be copied and ToolTips to be shown.
I often set it to read only or if you have to use disabled set the text box color to white and the font color to black.
Just make the text box Read-Only. And then if you need to set style, set it.

Our application has many TextBoxes that we disable at appropriate times. (We set the IsEnabled property to false). Our customer now wants the content of the TextBoxes to be non-changeable, but able to be copied. We can do this by setting IsReadOnly to true and IsEnabled to true.
I don't really want to go to every place in the application where text boxes change state and twiddle with those settings. How can I localize changes, such that I don't need to make a large number of edits? Basically, I want to do something that would be almost equivalent of redefining the set part of IsEnabled, when the value to be set is false. (BTW, our customer would also like us to do some other related changes, such as setting the background color of the text box to a non-default color when "disabling" the text box.)
One way to do this would be to create a subclass of TextBox that allowed you to make these type of changes. However that requires that you change your application to replace all occurrences of <TextBox ... with your control:
<myControl:MyTextBox....
which doesn't really solve your problem of not wanting to change all the code.
However, it would enable you to do the other changes you mention - changing the background colour, etc. a bit easier (though that can be also achieved by overriding the default style in XAML).
I dont really understand your question but I think it would be easiest to create a Background Worker that checks with if ( MyTextBox.Enabled == false ) if the textbox is enabled/disabled.
Is it possible some how to make the Text of the Textbox invisible or to hide it so the user can't see it , yet it get's the input/keys from the user?
It's better to rely on the built-in capabilities.
For instance, consider to use the TextBox.PasswordChar property.
You can set ForeColor = BackColor
Paste in your Properties -> Behavior -> PasswordChar symbol you need, empty blanks works too.
I have a TextBox disabled but would like the user to still be able to copy its content to the clipboard. However when IsEnabled is not set copy/paste is not allowed.
Is there a way to achieve this?
You're not really supposed to interact with a "disabled" control.
Instead, set the TextBox.IsReadOnly property to true.
If you want it to "look" disabled, you could set the background color to grey, like it is when it is disabled.
I am making a custom MessageBox in my own language (Persian). I want to know which component may I use for the text?
Label is not multiline and TextBox is a little bit not appropriate.
Which component does Visual Studio use itself?
What is the component I specified in the picture?
You can use a label. It has a number of options for laying out the text... One way is to set it to "AutoSize = True".
I support the answer of RQDQ, labels could be enlarged to occupy more than one line.
They have a property named TextAlign. When set to LeftCenter or MiddleCenter you could simulate the behavior of text in a message box. If the text doesn't fit in a single line, the label wraps it automatically on another line. However in this case I will let the property AutoSize to its false default value.
It all depends on what kind of Visual Studio project you are doing. Wpf or Silverlight or Asp.net or even windows, everything will depend upon which kind of project it is.
That looks to me like the MFC style label with an image, or in a browser it would be done with javascript.
You Can Use RichTextBox. I Use it For My Custom MessageBox And it works Correctlly
I need black forecolor in a disabled combobox. Is it possible?
I have searched around for information in the past about this, and as far as I can tell, the best solution is to change the DrawMode of the combo box to OwnerDrawFixed or OwnerDrawVariable and then write your own drawing code in the DrawItem event of the combo box.
I found this article that goes into much more detail about it. Hope it helps.
A "hack" I've used in the past for textboxes is to leave the control enabled, but capture the "OnFocus" event and immediately set the focus to some other object on the form, preferably a label since it doesn't show as being selected. I think this should work for comboboxes, too.
Not sure if your app is Winforms or WPF. The code given below works in a WPF app.
combo1.Items.Add("Item 1");
combo1.Items.Add("Item 2");
combo1.SelectedIndex = 0;
combo1.Foreground = Brushes.Black;
In my XAML I added a combo box and set its IsEnabled property to "false" then in the code behind I used the code given above and it does work.
HTH
All you need to do is say
combobox1.ForeColor = Color.FromName("Black");
It doesn't matter if the control is disabled or not, it should change the foreground color.
comboBox1.BackColor=Color.Black;
