Hi Francesca,
Thanks for your email. Code is working fine.
But here my requirement is I have a FPM Toggle Toolbar button to Hide/Dispaly. If I click Toogle toolbar button it should hide page master area again if I click on Toggle Toolbar button it should show Page master area. Here My FPM button in in Process_Event method. Please let me know how to achieve this functionality.
