The Most Bizarre Grid Crash After Editing

[Paul Gallen]

Hi,

I have sucessfully bounfd my collection the the grid.

After editing the contents in the Grid's Cell the application crashes, with a bizarre result: A File Dialog box pops open looking for :-
r:\WPF_Scrum\WPF_Team\Sources\Development\WPF\GridView\GridView\Cells\GridViewCell.cs.

What on earth!!!!


I cancel the box and and I get TargetInvocationException was unhandled exception

System.Reflection.TargetInvocationException was unhandled

Hello Paul Gallen,

You must be getting the R:\... path because we ship the pdb files with the assemblies. I am more worried about the exception though. I must admit I have never seen such a stack trace. Can you help me reproduce it? Posting some code would be great. Thanks!

Sincerely yours,

HI I was evaluating your WPF grid, not I did not save the source, but it does evolve around ADO entity. I found the same problem with your win forms grid pre SP1.

OK here are the steps to reproduce some of the problem(s) - (not exact code) 

Create an ADO Model from northwinds
Get a reference to a customer object  i.e Customer = (From c in cx.Customers.Incude("Orders")).First
Bind the orders to the grid from the customer  i.e Grid.ItemsSource = Customer.Orders.ToList

Add a new Order for the customer .ie. Dim Order as new Model.Order
                                                            Order.ShipCity="London"
                                                             Customer.Orders.Add(Order)

At this point your grid does not reflect any changes through the binding, Now, I know the Orders collection are not an IBindingList however, other vendors WPF grids do show the new order. 

 - (lost code)  - park your grid in edit mode on the newly added bound object

Edit the new object in your grid  - press return - and I get the formentioned error stack trace.

Hi Paul,

Unfortunately, this is a bug in the RadGridView - the collection is not wrapped appropriately. This issue will be fixed with our Q1 release.
Meanwhile, I can suggest you the following workaround:

customer = (from c in context.Customers.Include("Orders") select c).First();
GridView1.ItemsSource = ((IListSource)customer.Orders).GetList();

As for the exception, I've tried to reproduce it but to no avail. I've attached my test project.
Please, modify it so that the problem is reproduced and send it back to me.

Thanks Jordan

If I ever get the same stack trace again, I will pick up this thread and post it here again

I've just encountered the same problem. When is the Q1 coming out?
