Xamarin Forms: Open menu by custom button in MasterDetail based project










0















In my MasterDetail based project, I need a custom appearence for the navigation part for a specific detail page. To avoid rendering a custom Navigation, I set



 NavigationPage.SetHasNavigationBar(this, false);


so navigation disappear an then I create by grid a background and a button like:



<Grid>
<Image Source="BackgroundImage.png"/> <!-- This should fill the grid -->
<Image Source="back_button" HorizontalOptions="StartAndExpand" Aspect="AspectFit" >
<Image.GestureRecognizers>
<TapGestureRecognizer Tapped="Handle_Tapped"/>
</Image.GestureRecognizers>
</Image>
</Grid>


Handle_Tapped should be manage the open/hide menu of master detail. I think i need to manage the IsPresented properties like



 MasterDetailPage nav = new MasterDetailPage();
nav.IsPresented = true;


but that do nothing. Any help?

          You should be able to change the presentation via the IsPresented property. The problem with your attempt is, that you create a new MasterDetailpage instead of using the active one.



          Check if the current mainpage is a MasterDetailPage and change the presentation there:



          if (Application.Current.MainPage is MasterDetailPage mdp)

          mdp.IsPresented = true;



          Edit / important hint



          The above solution works only, if the current Mainpage is a MasterDetailPage. Otherwise you are not able to show the menu from the page.



          For a custom logic / custom slide-in/out menu, checkout the Nuget-Package "SlideOverKit".

          • But your DetailPage is part of a MasterDetailPage. Right? If so, try the code in my answer. The code checks the current MainPage for MasterDetailpage.

          • Tx. Putting your code on my Handle_Tapped, if clause is false. So my main page is not Masterdetail.

          • So I misunderstood you. Can you change the Navigation to use a MasterDetailPage as a parent? Instead of directly navigating to your DetailPage? That would be the right way. Otherwise you have to implement a custom logic to show a custom menu (I edited my answer)
