WinUI NavigationView Question

Question

Hi,

I have a question please. I have the following NavigationView's ItemInvoked:

private void NavigationViewControl_ItemInvoked(NavigationView sender, NavigationViewItemInvokedEventArgs args)
{
switch (sender.MenuItems.IndexOf(args.InvokedItemContainer))
{
case 0:
sender.Content = new Patient();
break;

    case 1:
        // sender.Content = new Patient();
        break;

    case 2:
        // sender.Content = new Patient();
        break;

    default:
        break;
}

}

What type is Patient file? is it a ContentPage, ConteView, Page, Window, etc?

Thanks,
Jassim

Hello,

Welcome to Microsoft Q&A!

what is the best way to do it?

Actually, the poster of the question that you shared already shows the correct way to navigate using NavigationView. You could put a Frame Object into NavigationView's content as the root frame. Then when the NavigationView item is clicked, call the Frame.navigate() to navigate to the target page.

A simple code snippet looks like this

Xaml

   <NavigationView ItemInvoked="NavigationView_ItemInvoked">  
            <NavigationView.MenuItems>  
                <NavigationViewItem Icon="Home" Tag="HomePage"/>  
                <NavigationViewItem Icon="Delete" Tag="DeletePage"/>  
                <NavigationViewItem Icon="Save" Tag="SavePage"/>  
                <NavigationViewItem Icon="Settings" Tag="SettingsPage"/>  
            </NavigationView.MenuItems>  
        Frame x:Name="rootFrame"/>  
        </NavigationView>  

Code behind

  private void NavigationView_ItemInvoked(NavigationView sender, NavigationViewItemInvokedEventArgs args)  
        {  
            var navItemTag = args.InvokedItemContainer.Tag.ToString();  
            switch (navItemTag)   
            {  
                case "HomePage":  
                    rootFrame.Navigate(typeof(HomePage));  
                    break;  
  
                case "DeletePage":  
                    rootFrame.Navigate(typeof(DeletePage));  
                    break;  
  
                case "SavePage":  
                    rootFrame.Navigate(typeof(SavePage));  
                    break;  
  
                case "SettingsPage":  
                    rootFrame.Navigate(typeof(SettingsPage));  
                    break;  
            }  
        }  

Besides, all of the pages like HomePage are Page objects.

Thank you.
