Hello everyone,
I'm having a Xamarin.forms application and what I'm trying to do is:
1) someone clicks on an item in a listview
2) the application shows a dialog to the user
3) the application waits until the user has pressed "yes" or "no"
4) as soon as there's input from the user, the application (code) continues again
I know that normally it's possible to make your method async and then apply an await on the DisplayAlert. However, because the code is so enormous, changing the method to async has a lot of effect on the rest of my code.. So I wondered if it's possible to call/await an asynchronous method from a synchronous method?
To show the dialog, I use the following code:
private async Task<bool> ShowDialog()
{
return await DisplayAlert("Question?", "Waiting for user input", "Yes", "No");
}
And to await the message box I use the following the code:
public void SyncMethod()
{
// Showing the listview here
// The user clicks an item
bool result = await ShowDialogAsync();
// after the user has clicked something,
// then continue with more code here.
if (result)
// Result = true
}
Unfortunately the SyncMethod needs to be async. Is there a way to solve this without making this method async? Thanks for the answer
