give same property to all textbox controls

Question

how to give same property to all textboxes present in the same form.

      foreach (var textbox in this.Controls.OfType())
        {
            t         


        

Answer 1

Just use the recursion to go through all controls subcollections:

void SetControl(ContextMenu menu, Control control)
{
    if (control is TextBox)
        control.ContextMenu = menu;
    else
    {
        foreach (Control c in control.Controls)
            SetControl(menu, c);
    }
}

It will find all the textboxes and set one and the same context menu to all of them.

You mal call it,say, from form's OnLoad event handler. While it's assumed that you have yourContextMenu defined for the form.

    private void Form1_Load(object sender, EventArgs e)
    {
        SetControl(yourContextMenu, this);
    }
