Using Datagrid with LINQ crashes the browser?

03-10-2008 10:56 AM |

Hello,

I'm having some problems in using DataGrid with LINQ. 

The following code makes crashing the IE7. 

                     XDocument xmlProducts = XDocument.Parse(xmlContent);

                    var products = from product in xmlProducts.Descendants("Product")
                                   select new
                                   {
                                       ProductID = Convert.ToInt32(product.Element("ProductId").Value),
                                       ProductName = (string)product.Element("ProductName").Value
                                   };

                    datagrid1.ItemsSource = products;

Env:

1) Vista Home Premium (32)
2) VS 2008  + SL2 (beta1)
3) IE7

Let me know if you need more details.  

Note:

If you are using class and List<T> like the example from doc, it's working fine. but why not work with LINQ and implicitly-typed variable?

Try to use a ListBox to bind to an internal class, you'll find a similar problem.

Hello Yi-lun,

I just tired to use ListBox instead of Datagrid. it's working fine. Could you please review this issue?

Hi Michael, sorry for the late response. But I really don't see how you get it to work with ListBox. This is a known bug. swildermuth (The ADO Guy) already reported this issue on a ListBox from the Jolt private connect. Any ItemsControl bound to internal types will cause this problem. While data binding to internal types such as anonymous types are not supported, we understand we should not hang the browser. Our developers are investigating this issue.
