not getting the data of textblock or textbox saved when we reload what i need to do ?????
i have tried in this way:
i added LayoutAwarePage.cs and SuspensionManager.cs in common folder
then in app.xaml.cs file
1)i made some changes in onlaunched method(changes are indicated as //<---)
protected async override void OnLaunched(LaunchActivatedEventArgs args)
{
Frame rootFrame = Window.Current.Content as Frame;
// Do not repeat app initialization when the Window already has content,
// just ensure that the window is active
if (rootFrame == null)
{
// Create a Frame to act as the navigation context and navigate to the first page
rootFrame = new Frame();
ApplicationLifeCycle.Common.SuspensionManager.RegisterFrame
(rootFrame, "appFrame"); //<-----
if (args.PreviousExecutionState == ApplicationExecutionState.Terminated)
{
//TODO: Load state from previously suspended application
await ApplicationLifeCycle.Common.SuspensionManager.RestoreAsync(); //<----
}
// Place the frame in the current Window
Window.Current.Content = rootFrame;
}
2) i made some changes to onsuspending method
private async void OnSuspending(object sender, SuspendingEventArgs e)
{
var deferral = e.SuspendingOperation.GetDeferral();
//TODO: Save application state and stop any background activity
await ApplicationLifeCycle.Common.SuspensionManager.SaveAsync(); //<----
deferral.Complete();
}
in mainpage.xaml.cs
here nameInput is the name of textbox and greetingOutput is the name of textblock
wrote a method Loadstate
protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState)
{
// Restore values stored in session state.
if (pageState != null && pageState.ContainsKey("greetingOutputText"))
{
greetingOutput.Text = pageState["greetingOutputText"].ToString();
}
// Restore values stored in app data.
Windows.Storage.ApplicationDataContainer roamingSettings =
Windows.Storage.ApplicationData.Current.RoamingSettings;
if (roamingSettings.Values.ContainsKey("userName"))
{
nameInput.Text = roamingSettings.Values["userName"].ToString();
}
}
wrote a method Savestate:
protected override void SaveState(Dictionary<String, Object> pageState)
{
pageState["greetingOutputText"] = greetingOutput.Text;
pageState["userName"] = nameInput.Text;
}
changed public sealed partial class MainPage : Page
to
public sealed partial class MainPage : ApplicationLifeCycle.Common.LayoutAwarePage
In the mainpage
1)page attribute is changed to common:LayoutAwarePage
and added xmlns:common="using:DataSuspension.Common"
but still not getting the data of textblock or textbox saved when we reload what else i need to do ?????
