Burger menu hiding when calling a new view Xamarin Forms

Question

I have a View which is being called through a button of the MenuItem. But within those View contains another button that calls a new button View. This new View opens off the burger menu, ie it hides itself.

I need this new View continue displaying the menu just above as in the first image.

I’ve used the PushModalAsync and the PushAsync but continues that way.

How to fix this navigation problem ?

Answer 1

Using Messagingsender in Xamarin we can make a navigation detailpagechanged that keeps the menu instead of queued navigation (push and pop) .

        MessagingCenter.Subscribe<Page>(this, "DetailPageChanged", (page) =>
        {
            DetailPageChanged(page);
        });

    private void DetailPageChanged(Page page)
    {
        var currentDetailPage = Detail as HoldingPage;
        if (currentDetailPage != null)
        {
            var internalPage = currentDetailPage.CurrentPage as IDisposable;
            if (internalPage != null)
            {
                internalPage.Dispose();
            }
        }

        var holdingPage = new HoldingPage();

        holdingPage.PopAsync();

        holdingPage.PushAsync(page);
        Detail = holdingPage;
    }

You can create a Helper and call the method this way :

    public static void SendDetailPageChanged(Page detailPage)
    {
        MessagingCenter.Send<Page>(detailPage, "DetailPageChanged");
    }
