Disable Control From Other Form

Question

I have a Form 1 that opens Form2. How I make all textBox readonly in Form2 opens?

Form 1:

Form2 f2 = new Form2();
f2.ReadOnly();
f2.ShowDialog();

Form 2:

public void ReadOnyTextBoxes(Control parent)
{
    foreach (Control c in parent.Controls)
    {
        if (c.GetType() == typeof(TextBox))
        {
            ((TextBox)(c)).ReadOnly = true;
        }
    }
}

public void ReadOnly()
{
     ReadOnyTextBoxes(groupBox1);
}

What is your actual problem? Your code seems to work OK. – King King Jul 27 '13 at 19:24 — King King, Jul 27 '13 at 19:24
The textBoxes in Form2 are still not ReadOnly – Square Ponge Jul 27 '13 at 19:32 — Square Ponge, Jul 27 '13 at 19:32

there could be other groupboxes or some containers in groupbox1. you need recursion. How to disable all controls on the form except for a button?

Working with your idea, in order to make it work on all TextBoxes you could do this with a recursive function, something like:

public void MakeReadOnlyTextBoxes(Control parent)
{
    foreach (Control c in parent.Controls)
    {
        if (c.GetType() == typeof(TextBox))
        {
            ((TextBox)(c)).ReadOnly = true;
        }
        else if(c.Controls.Count > 0)
        {
            MakeReadOnlyTextBoxes(c);
        }
    }
}

public void ReadOnly()
{
     ReadOnyTextBoxes(this);
}

Edited: you should use the c variable at the recursive call
