Making controls read only within a group box

[southstander132]

Greetings,

 

I know how to loop thru controls in a groupbox and disable them, or make the entire groupbox enabled = false, but the users say they can't see the text when the fields are disabled - the color is greyed out and too light.  I can't figure out how to make these fields (text boxes, comboboxes, etc.) readonly instead.  I get the error: 

 

Error 2 'System.Windows.Forms.Control' does not contain a definition for 'Readonly' and no extension method 'Readonly' accepting a first argument of type 'System.Windows.Forms.Control' could be found (are you missing a using directive or an assembly reference?) 

 

Is there any way to do this?  Or are they just stucked with greyed out text?

 

Thanks so much in advance!

Hi southstander132,

You can simpy do this trick so user can see the text even the control
is disable:

textBox1.ReadOnly = true;
textBox1.ForeColor = Color.Black;
textBox1.BackColor = Color.Yellow;

Just don't use 'SystemColors' for the ForeColor or BackColor value,
because the result will be difference in difference system/OS/Theme
windows.

You're missing the cast to the type of control you are referencing.
The Controls property lists a collection of all child controls
implicitly cast as the base Control class. The error message is
correctly telling you that the Control class does not have a ReadOnly
property.

For example,

---

private void ToggleControls(bool enabled)
{
foreach(Control ctl in MyGroupBox.Controls)
{
if (ctl is TextBox)
{
TextBox txt = ctl as TextBox;
txt.ReadOnly = enabled;
}
else if (ctl is ComboBox)
{
ComboBox cmb = ctl as ComboBox;
cmb.Enabled = enabled;
}
}
}

That's exactly what I couldn't figure out how to do - thanks much - worked like a charm and I am moving forward!
