Reload the datasource of your grid after the update
更新后重新加载网格的数据源
myGrid.ItemsSource = null;
myGrid.ItemsSource = myDataSource;

I had a lot of trouble with this and this is what helped me get the DataGrid reloaded with the new values. Make sure you use the data type that your are getting the data from to get the latest data values.
我在这方面遇到了很多麻烦，这就是帮助我使用新值重新加载 DataGrid 的原因。确保使用从中获取数据的数据类型来获取最新数据值。
I represented that with SomeDataTypebelow.
我用SomeDataType下面的表示。
DataContext.Refresh(RefreshMode.OverwriteCurrentValues, DataContext.SomeDataType);
Hope this helps someone with the same issues I had.
希望这可以帮助遇到与我相同问题的人。
