I have used master detail page to create an hamburger Menu. I would like to have a menu with 3 items initially, once user logged in, the menu should be changed to 4 items.
<MasterDetailPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:xxx"
x:Class="xxx.MainPage">
<MasterDetailPage.Master>
<local:MasterPage x:Name="MasterPage"></local:MasterPage>
</MasterDetailPage.Master>
<MasterDetailPage.Detail>
<NavigationPage>
<x:Arguments>
<local:Pages.LoginPage></local:Pages.LoginPage>
</x:Arguments>
</NavigationPage>
</MasterDetailPage.Detail>
</MasterDetailPage>
Main Page.axml.cs
public partial class MainPage : MasterDetailPage
{
public MainPage()
{
InitializeComponent();
MasterBehavior = MasterBehavior.Popover;//new
MasterPage.listView.ItemSelected += OnItemSelected;
Master = MasterPage;
NavigationPage page = new NavigationPage(new Pages.LoginPage());
page.BarBackgroundColor = Color.FromHex("#29B6F6");
Detail = page;
}
private void OnItemSelected(object sender, SelectedItemChangedEventArgs e)
{
var item = e.SelectedItem as ClassFiles.MasterPageItem;
if (item!=null)
{
Page displayPage = (Page)Activator.CreateInstance(item.TargetType);
NavigationPage page = new NavigationPage(displayPage);
page.BarBackgroundColor = Color.FromHex("#29B6F6");
Detail = page;
//Detail = new NavigationPage((Page)Activator.CreateInstance(item.TargetType));
MasterPage.listView.SelectedItem = null;
IsPresented = false;
}
}
}
Master Page.axml

listView.ItemsSource = masterpageItem;
}
}
Login.axml.cs
async void Login_Procedure(object sender, EventArgs e)
{
tbl_Login objLogin = new tbl_Login();
objLogin.UserName = EntryUsername.Text;
objLogin.Password = EntryPassword.Text;
if (objLogin.checkInformation())
{
if (data.GetLoginUserDetails(objLogin))
{
Navigation.InsertPageBefore(new Pages.HomePage(), this);//Navigate to Home page in master details relation
await Navigation.PopToRootAsync();
}
else
{
Error_label.IsVisible = true;
Error_label.Text = "Please Enter valid Credentials";
//await DisplayAlert("Login", "Please Enter valid Credentials", "OK");
}
}
