I have a WPF DataGrid with some data. You can add rows through a separate window. The DataContext is the same, a LINQ-to-SQL object. Binding is also the same, I bind the ItemsSource property to a table.
In the other window, when the user clicks on Save, I create a row programmatically and add it using InsertOnSubmit. After that I use the DataContext's SubmitChanges method.
My problem is that the DataGrid isn't updated. If I restart the application I can see the new row, so it's in the database, but I couldn't find a way to refresh the DataGrid.
So far I've tried to use UpdateTarget on the BindingExpression of the DataGrid, but it didn't help. I've also tried dataGrid.Items.Refresh() — same result. How can I fix this?

A DataGrid is a control that displays data in a customizable grid. It provides a flexible way to display a collection of data in rows and columns. The hierarchical inheritance of DataGrid class is as follows −
WPF DataGrid (SfDataGrid) provides built-in row called AddNewRow. It allows user to add a new row to underlying collection. You can enable or disable by setting SfDataGrid.
try datagrid.Items.Refresh() from here http://programmer.wrighton.org/2009/01/wpf-datagrid-items-refresh.html
