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;
}
}
}
