我有一個數(shù)據網格,顯示一個綁定到DataSource的表,該數(shù)據源不斷更改時間約束.

如何在更新myDataSource值時刷新數(shù)據網格的內容.

P.S：我的DataSource表中的值由監(jiān)控系統(tǒng)更新.其表值定期更新.

我應該在EF中添加我的Observable Collection？

private IQueryable GetMyTablesQuery(TestDBEntities1 testDBEntities1 )

{

// definition of a Query to retrieve the info from my DB

System.Data.Objects.ObjectQuery myTablesQuery = testDBEntities1.MyTables;

// Returns an ObjectQuery.

return myTablesQuery ;

}

private void Window_Loaded(object sender, RoutedEventArgs e)

{

// A New entity container is created that uses the object context

var testDBEntities1 = new EF_demo1.HMDBEntities1();

// Load data into MyTables.

var myTablesViewSource= ((System.Windows.Data.CollectionViewSource)(this.FindResource("myTablesViewSource")));

// the query which is defined above is executed here. It grabs all the information from the entity container

IQueryable myTablesQuery = this.GetMyTablesQuery(testDBEntities1 );

//The query result is binded to the source of the myTablesViewSource, which inturn binds back to the list.

myTablesViewSource.Source = myTablesQuery .ToList();

}
