Does anyone know which property sets the text color for disabled control?
I have to display some text in a disabled TextBox
and I want to set its color to black.

Just handle Enable changed and set it to the color you need
private void TextBoxName_EnabledChanged(System.Object sender, System.EventArgs e)
{
((TextBox)sender).ForeColor = Color.Black;
}

I've just found a great way of doing that. In my example I'm using a RichTextBox but it should work with any Control:
public class DisabledRichTextBox : System.Windows.Forms.RichTextBox
{
// See: http://wiki.winehq.org/List_Of_Windows_Messages
private const int WM_SETFOCUS = 0x07;
private const int WM_ENABLE = 0x0A;
private const int WM_SETCURSOR = 0x20;
protected override void WndProc(ref System.Windows.Forms.Message m)
{
if (!(m.Msg == WM_SETFOCUS || m.Msg == WM_ENABLE || m.Msg == WM_SETCURSOR))
base.WndProc(ref m);
}
}
You can safely set Enabled = true and ReadOnly = false, and it will act like a label, preventing focus, user input, cursor change, without being actually disabled.
See if it works for you. Greetings

In addition to the answer by @spoon16 and @Cheetah, I always set the tabstop
property to False on the textbox to prevent the text from being selected by default.
Alternatively, you can also do something like this:
private void FormFoo_Load(...) {
txtFoo.Select(0, 0);
}
or
private void FormFoo_Load(...) {
txtFoo.SelectionLength = 0;
}

If you want to display text that cannot be edited or selected you can simply use a label

NOTE: see Cheetah's answer below as it identifies a prerequisite to get this solution to work. Setting the BackColor
of the TextBox
.
I think what you really want to do is enable the TextBox
and set the ReadOnly
property to true
.
It's a bit tricky to change the color of the text in a disabled TextBox
. I think you'd probably have to subclass and override the OnPaint
event.
ReadOnly
though should give you the same result as !Enabled
and allow you to maintain control of the color and formatting of the TextBox
. I think it will also still support selecting and copying text from the TextBox
which is not possible with a disabled TextBox
.
Another simple alternative is to use a Label
instead of a TextBox
.

You can try this. Override the OnPaint event of the TextBox.
protected override void OnPaint(PaintEventArgs e)
{
SolidBrush drawBrush = new SolidBrush(ForeColor); //Use the ForeColor property
// Draw string to screen.
e.Graphics.DrawString(Text, Font, drawBrush, 0f,0f); //Use the Font property
}
set the ControlStyles to "UserPaint"
public MyTextBox()//constructor
{
// This call is required by the Windows.Forms Form Designer.
this.SetStyle(ControlStyles.UserPaint,true);
InitializeComponent();
// TODO: Add any initialization after the InitForm call
}
Or you can try this hack
In Enter event set the focus
int index=this.Controls.IndexOf(this.textBox1);
this.Controls[index-1].Focus();
So your control will not focussed and behave like disabled.

hi set the readonly attribute to true from the code side or run time not from the design time
txtFingerPrints.BackColor = System.Drawing.SystemColors.Info;
txtFingerPrints.ReadOnly = true;

Additionally, in order for ForeColor to be obeyed on a TextBox marked ReadOnly, you must explicitly set the BackColor. If you want to have it still use the default BackColor, you have to make the set explicit, as the designer is too smart for its own good here. It is sufficient to set the BackColor to its current value. I do this in the Load event for the form, like so:
private void FormFoo_Load(...) {
txtFoo.BackColor = txtFoo.BackColor;
}
