Gets a value that indicates whether the task can be processed in parallel with other tasks.

 property bool ExecuteInParallel { bool get(); };

Public ReadOnly Property ExecuteInParallel As Boolean

Property Value

Boolean

true if the task should be processed in parallel with other tasks; otherwise, false.

Examples

The following code example defines three asynchronous tasks that are each set to be processed in parallel. This example is part of a larger example found in the PageAsyncTask class overview.

PageAsyncTask asyncTask1 = new PageAsyncTask(slowTask1.OnBegin, slowTask1.OnEnd, slowTask1.OnTimeout, "Async1", true);
PageAsyncTask asyncTask2 = new PageAsyncTask(slowTask2.OnBegin, slowTask2.OnEnd, slowTask2.OnTimeout, "Async2", true);
PageAsyncTask asyncTask3 = new PageAsyncTask(slowTask3.OnBegin, slowTask3.OnEnd, slowTask3.OnTimeout, "Async3", true);

// Register the asynchronous task.
Page.RegisterAsyncTask(asyncTask1);
Page.RegisterAsyncTask(asyncTask2);
Page.RegisterAsyncTask(asyncTask3);

Dim asyncTask1 As New PageAsyncTask(AddressOf slowTask1.OnBegin, AddressOf slowTask1.OnEnd, AddressOf slowTask1.OnTimeout, "Async1", True)
Dim asyncTask2 As New PageAsyncTask(AddressOf slowTask2.OnBegin, AddressOf slowTask2.OnEnd, AddressOf slowTask2.OnTimeout, "Async2", True)
Dim asyncTask3 As New PageAsyncTask(AddressOf slowTask3.OnBegin, AddressOf slowTask3.OnEnd, AddressOf slowTask3.OnTimeout, "Async3", True)

' Register the asynchronous task.
Page.RegisterAsyncTask(asyncTask1)
Page.RegisterAsyncTask(asyncTask2)
Page.RegisterAsyncTask(asyncTask3)

Remarks

The ExecuteInParallel property is set in the constructor. When multiple tasks are registered in a page and the ExecuteInParallel property is set to true, then those tasks are processed concurrently. However, if the ExecuteInParallel property is set to false, then those tasks are processed sequentially. For example, if a page contained two asynchronous tasks that each took 5 seconds to complete and ExecuteInParallel is set to true, both tasks will complete in 5 seconds. If ExecuteInParallel is set to false for these same two tasks, then the first task will complete in 5 seconds and the second task will complete 5 seconds after the completion of the first task.
