Hi:

I want to change gridview style and I am using Blend to do that.

I have created a gridview in Blend and then I've changed some properties like RowStyle and some other more. I can see the changes in the designer and the project compiles well and when I execute it, it works well.
The problem is that if I close the project and then I open it, blend doesn´t show anything or it shows me a message:

Se obtuvo una excepcion

Excepcion: XAML no valido (Exception: not valid XAML)
StackTrace: vacio (StackTrace: empty)
Excepcion interna: XAML no valido.
    Exception: XAML no valido
    StackTrace: vacio
    InnerException: ninguna (none)

It marks a red line in a part of the Xaml, but if I execute it, it works well and I can see the gridview with changes. It's very frustrating because I need to use blend to change the style of radgridview because of gridview's complexity.

I hope you can help me.
Perhaps it's only a bug of Blend.

Thanks.

Celeste.

I am using Silverlight 2.
I don´t know why it's happening that, but my big problem it's the next: creating a new project, I edit gridview template. Then in PART_RootItemsControl I choose edit a copy and then it shows me a message with NullReferenceException in Blend's window designer.
I can see the gridview until this point. But then (with this existing code of the GridViewItemsControlTemplate) if I click in the first template (GridViewTemplate) from window Resources, I can see the gridview again.
Do I have to add a dll or something?

Thanks

Celeste.
