is there a best way to manage a form in WPF application which has asynchronous execution commands?
1) Suppose you have a form where user
enters all his data and clicks on Ok
button to save changes.2) Your WPF app starts an asynchronous
method to record those data.3) Now suppose the database server is
down, and the operation is taking
about 15 seconds to get finished. At
this time, user has already closed the
WPF form (he did not wait for the
transaction to be finished).
So that’s my question: how could you control when to let user close or not the form?
thank you
Easy answer…don’t let the user close the form until the operation is complete.
You can accomplish this with a Modal infinitely scrolling progress bar. It provides feedback to the user that your application is doing something…but doesn’t let the user close the window they were working in.
This allows you to run your code outside the UI thread and then when your code completes (either finishes or errors out) you can provide feedback to the user about what happened (either success or something happened and they need to save again).
