WPF implements the function of refreshing the UI interface regularly

This article shares the specific code for WPF timed refresh UI interface display for your reference. The specific content is as follows

Code:

namespace 
{
 public partial class MainPage : UserControl
 {
  private  timerNotice = null;

  public MainPage()
  {
   InitializeComponent();
  }

  private void MainPage_Loaded(object sender, RoutedEventArgs e)
  {
   #region Notices   if (timerNotice == null)
   {
    BindNotice();

    timerNotice = new ();
     += new ((o, eea) =&gt;
    {
     BindNotice();
    });
     = 60 * 1000;
    ();
   }
   #endregion
  }

  private void MainPage_SizeChanged(object sender, SizeChangedEventArgs e)
  {

  }

  #region Binding Notification Announcement  private void BindNotice()
  {
   (() =&gt;
   {
    try
    {
     int total = 0;
     TES_NOTICE info = new TES_NOTICE();
     IList&lt;TES_NOTICE&gt; list = new List&lt;TES_NOTICE&gt;();

     list = &lt;INoticeService&gt;().GetListPage(null, , , 1, 50, ref total);

     (new Action(() =&gt;
     {
       = list;
     }));
    }
    catch
    {

    }
   });
  }
  #endregion

 }
}

Note: Using BackgroundWorker in the event is invalid, that is, the following code cannot refresh the interface normally:

using ;
using System;
using ;
using ;
using ;

namespace 
{
 public partial class MainPage : UserControl
 {
  private  timerNotice = null;

  public MainPage()
  {
   InitializeComponent();
  }

  private void MainPage_Loaded(object sender, RoutedEventArgs e)
  {
   #region Notices   if (timerNotice == null)
   {
    BindNotice();

    timerNotice = new ();
     += new ((o, eea) =&gt;
    {
     BindNotice();
    });
     = 60 * 1000;
    ();
   }
   #endregion
  }

  private void MainPage_SizeChanged(object sender, SizeChangedEventArgs e)
  {

  }

  #region Binding Notification Announcement  private void BindNotice()
  {
   PT_USER_INFO user = new PT_USER_INFO();
   IList&lt;TES_COMBAT_TASK&gt; taskList = new List&lt;TES_COMBAT_TASK&gt;();

   BackgroundWorker worker = new BackgroundWorker();
    += (s, e) =&gt;
   {
    user = &lt;&gt;().();
    taskList = &lt;ITaskService&gt;().GetCombatTaskByUserIDUnfinished(());

   };
    += (s, e) =&gt;
   {
    try
    {
      = taskList;
    }
    catch { }
   };
   ();
  }
  #endregion

 }
}

You can also use DispatcherTimer to refresh the interface, but time-consuming operations cannot be performed in the DispatcherTimer event, otherwise the interface will be stuck. Therefore, time-consuming and time-consuming timed operations, such as querying the database, need to use another one, which is relatively troublesome.
