call pre function of mui component page only when required
Can PRE function of a MUI dialog be called only when required?

!define MUI_PAGE_CUSTOMFUNCTION_PRE SkipComponentsPage
!insertmacro MUI_PAGE_COMPONENTS

Function SkipComponentsPage
Abort
MessageBox MB_OK "You chose to UPDATE your current version"
FunctionEnd
//This section will be checked by default, that is , user will not be able to select or unselect this section , this has to be executed..........how to do this?To hide it , i have included a - sign in its name. its name is "mandatory"

Section "-mandatory" SEC_UPDATE
#Do update............
SectionEnd
I have two RadioButtons (Demo & Update) on my custom dialog page in the NSIS installer. I want that when the user choses to install the UPDATE (choses the UPDATE RadioButton), then the Components Page is skipped , and a specified Section is auto CHECKED and executed.

But if the user choses to install the DEM (choses the DEMO RadioButton) , then the Components page is not skipped & the user can Check or Uncheck Sections on that Component page

in your custom page's leave function, store the state of the radiobutton in a variable. Then do

Function SkipComponentsPage
${If} $yourVar == "update"
Abort
${EndIf}
FunctionEnd
