Invoke OnChange event hangs if Alert appears

[Denis]

Hi Telerik Support Team,

In our application we have the following scenario which need to be verified: 
User enter a value into some input text box and change focus to another control. After verification JavaScript alert appears on the screen.

In code it looks like:

01 var alertDialog = AlertDialog.CreateAlertDialog(Manager.Current.ActiveBrowser, DialogButton.OK);
02 Manager.Current.DialogMonitor.AddDialog(alertDialog);
03 Manager.Current.DialogMonitor.Start();
04 DateInputBox.Focus();
05 DateInputBox.Value = "01/01/20014";
06 DateInputBox.InvokeEvent(ScriptEventType.OnChange);
07 DateInputBox.InvokeEvent(ScriptEventType.OnBlur);
08 alertDialog.WaitUntilHandled(15000);

During line 06 execution JavaAcript Alert appers and script hangs on the 06 line for a long time. The only one solution is to stop test execution. 

Do you have any suggestion how to implement the scenario?

Hello Denis,

The only solution I can think of is multi-threading. Put lines 4 - 7 into a worker thread that is spawned by the main thread. The main thread can also pass it a parameter pointing to the DateInputBox object so the worker thread doesn't have to look this up, it simply operates on the object passed into the thread as a parameter. Keep the WaitUntilHandled in the main thread which will execute concurrently with the worker thread that's setting the value and invoking the events.
