Programmatically dismiss a MessageDialog

由 橙三吉。 提交于 2019-12-10 18:08:20
问题 On Windows Phone 8.1, how to programmatically dismiss a MessageDialog after the ShowAsync call? I’ve tried calling IAsyncInfo.Close(), it just throws an InvalidOperationException "An illegal state change was requested". I’ve tried calling IAsyncInfo.Cancel(). The dialog stays visible, the only result - after I tap the “Close” button, TaskCancelledException is marshaled to the awaiting routine. Update: exact behavior depends on the sequence of the calls. If IAsyncOperation.Cancel() is invoked

I have a ViewModel which instantiates an event in a synchronous method. The event signals to the UI that we need a "Yes" or "No" answer from the user before continuing. I am trying to display a MessageDialog and wait until the user provides an answer - Yes or No. I am having a difficult time doing this. I currently get an UnauthorizedAccessException when trying to do this. Here's a look at the code in the UI: async Task<bool> Instance_SwitchConfirmation(string question) { MessageDialog md = new MessageDialog(question); md.Commands.Add(new UICommand("Yes", CommandInvokedHandler)); md.Commands

Windows Phone 8.1 override back button on a certain page

由 此生再无相见时 提交于 2019-11-28 07:06:19
I am developing a WP 8.1 XAML app. The first page is a login page, the second for example a history page. There will be more pages, but it doesn't matter at the moment. When I press the login button on the login page, the second (history) page appears. If I press the (physical) back button on the history page, it goes back to the login page. But I would like to disable this function. Instead of this I would like when I press the back button a MessageDialog appears and if I press again within a few seconds (for example 3 secs) the app terminates. I tried to find the answer for my questions, but

The dialog box shows fine the first time, but on clicking try again and failing again, I get a access denied exception on calling ShowAsync.
