Make a globle function and call this function at load event for every form public void colorchange() { Action Control . ControlCollection > coll = null ; foreach (Control c in coll) { if ( c is TextBox ) ( control as TextBox ). BackColor = Color . blue ; } } }

ok,but i need this code in all forms. so, can i access this globally instead of writing this code again and again

Michal Habalcik · Answer

this code changes the color of all textboxes in the parent container (e.g. form, groupcontrol, ...). However, if the textboxes are nested in some container, you need to iterate it as well. foreach ( var control in this .Controls) { var box = control as TextBox ; if (box != null ) box.BackColor = Color .Red; }
