Question

In C# form window, say i have 5 controls. I have just hide some of them. When I run the program just the (Visible=true) controls should appear. I want to click a button to appear or unhide all controls. How can i do that?

Answer 1

You could make it recursive, then if you have any panels/group boxes their children get made visible too.

public void MakeVisible(Control control)
{
    if(control.HasChildren)
    {
        foreach (Control child in control.Controls)
        {
            MakeVisible(child);
        }
    }
    control.Visible = true;
}
