hide "all" textboxes together when button is clicked

How to hide "all" textboxes together when button is clicked? Is there any short method to avoid hiding them one by one?

gamma_textBox.Visible = false;

You could use this generic, recursive method:

private void ProcessAllControls<T>(Control rootControl, Action<T> action)where T:Control
{
    foreach (T childControl in rootControl.Controls.OfType<T>())
    {
        action(childControl);
    }
    foreach (Control childControl in rootControl.Controls)
    {
        ProcessAllControls<T>(childControl, action);
    }
}

It works this way:

ProcessAllControls<TextBox>(this, txt=> txt.Visible = false);

This method searches recursively all child controls of a given container control for controls of a specified type. Then it applies an action(in this case it changes Visibility).

If you want it for any kind of control, use the non-generic overload:

public static void ProcessAllControls(Control rootControl, Action<Control> action)
{
    foreach (Control childControl in rootControl.Controls)
    {
        ProcessAllControls(childControl, action);
        action(childControl);
    }
}

If you using Winforms, you can do it like;

for (int i = 0; i < this.Controls.Count; i++)
{
   if (this.Controls[i].GetType().ToString() == "System.Windows.Forms.TextBox")
       this.Controls[i].Visible = false;
}

foreach(var tb in this.Controls.OfType<TextBox>()) tb.Visible = false;

But note this will not look inside any containers. You can do so recursively though by enumerating each child's Controls collection. An example of this would be:

public void HideChildTextBoxes(Control parent)
{
    foreach(Control c in parent.Controls)
    {
        HideChildTextBoxes(c);
        if(c is TextBox) c.Visible = false;
    }
}

You can put all textbox into a LIST(Or array),then use a for iteration to make them invisiable.

Paste them into panel(or other container), and set visibility of that panel.
