Hi Ronak,
Thank you for contacting Syncfusion Support.
Since, Our SfNavigationDrawer control is a ContentView control, so that we can only change the content view of it. If we use NavigationPage, then the navigated page does not contains Our SfNavigationDrawer.
To achieve your requirement by using our SfNavigationDrawer we have prepared a sample for your reference, please download it from the link given below.
Sample link:
http://www.syncfusion.com/downloads/support/directtrac/general/ze/NavigationDrawer2_22086459981 In this sample we have used two rows of grid, in the 1st row we have placed the hamburger icon and a header label. In the 2nd row we have placed our SfNavigationDrawer control.
When the user clicks on to a DrawerContentView to change the ContentView of SfNavigationDrawer, a Back button will get visible on the 1st grid.
Please run the sample and check whether it meets your requirement, if not please update us with more information regarding your query.
Regards,
Selva Kumar V.
