Hi,
I am using Visual Studio 2012 Ultimate, create a WPF application which loads in Customer data of 91 rows from Northwind database, using ADO.NET Entity Data Model.
The horizontal scrollbar is ok to refresh the data, I am able to drag it and the DataGrid is able to scroll to the left and right smoothly.
But for the vertical scrollbar, I am not able to drag it up or down easily. I can only click it at the top or bottom of the vertical scrollbar, and the DataGrid needs 5 seconds to be able to scroll up or down, which is not acceptable.
Has anyone encounter anything like this before?
I am using Windows 7 SP1, with 2GB RAM.
I will try to verify whether I have the same problem when using Visual Studio 2010.
thanks.
================
I realise the culprit has to do with this line of code:
dataGrid1.ItemsSource = context.Customers.ToList();
but if I do not have the above line code, and with only below code, DataGrid does not get updated.
dataGrid1.Items.Refresh();
the full code is as attached.
