Deriving from GridView throws exception

Question

I am using win8 CP and vs2011 beta.

I tried to derive from GridView with the following code and I get

Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

What am I doing wrong?

 xmlns:local="using:Application1"

  <local:MyGridView x:Name="list1" >
           
        </local:MyGridView>

 public class MyGridView : GridView
    {
        public MyGridView()
        {
            DefaultStyleKey = typeof(GridView);
        }

    }

Answer 2

Hi,

That is all the code I have in the project, other than the code generated by default.

I am mistaken. If I give the gridview a name and set the ItemsSource in code. I get that exception

If I do it from resource like below and set source of cvs it works.

<Page.Resources>
        <CollectionViewSource x:Name="cvs"/>
    </Page.Resources>

 var items = Enumerable.Range(0, 100).Select(x => new Customer { Id = x, Name = "person.." + x.ToString() });
           // gridview1.ItemsSource =items; -- exception

           // cvs.Source = items; -- this works

Answer 6

Hi Lee - this is a known bug that we're working on. The bug happens when setting ItemsSource on a list control.

Answer 7

Hello Matt,

I'm seeing the same issue, though I see it occuring even with this syntax:

           // cvs.Source = items;

Do you have any update if/when there will be a fix?

Answer 8

In any case, it definitely won't be in CP.

Matt, this issue (Catastrophic failure at setting ItemsSource property and at clearing Items property) is a show stopper. Can you confirm that it is  fixed in some upcoming version or should I post it to MS connect?
