c# - XNA: My richtextbox is invisible when fullscreen is toggled -

i have added richtextbox in xna invisible when fullscreen toggled

this code:

    richtextbox richtextbox1 = new richtextbox();     public engine()     {         graphics = new graphicsdevicemanager(this);         content.rootdirectory = "content";         this.ismousevisible = false;         graphics.preferredbackbufferwidth = 1280;         graphics.preferredbackbufferheight = 720;         graphics.isfullscreen = true;     }      protected override void initialize()     {         richtextbox1.location = new system.drawing.point(100, 100);         richtextbox1.name = "richtextbox1";          richtextbox1.size = new system.drawing.size(100, 100);         richtextbox1.tabindex = 0;         richtextbox1.text = "";         control.fromhandle(window.handle).controls.add(richtextbox1);     } 

the code above working fine if graphics.isfullscren set false

when set direct x run full screen, form no longer visible. when form not visible, controls not visible.

you better of implementing own ui textbox. bit of work, not bad may seem...
