Problems upgrading to 2009 Q2 SP1

[Kevin]

Hi I have just upgraded to SP1, removed the old references from my project and added the new ones but I now get the following unhandled exception when I open my main.xaml in VS2008

'-17' is not a valid value for property 'ViewportSize'.
   at System.Windows.DependencyObject.SetValueCommon(DependencyProperty dp, Object value, PropertyMetadata metadata, Boolean coerceWithDeferredReference, OperationType operationType, Boolean isInternal)

Any advice?

Thanks in advance,

Can someone please help out with this. I have looked everywhere for the 'ViewportSize' property but cant find it.

I cant continue to develop with this resolved.

Cheers,
Kevin.

Hi Kevin,

We have already fixed a problem related to the ViewportSize (similar to the described one) which we had reproduced when the following preconditions were available:

1. Window's SizeToContent="WidthAndHeight"
2. RadGridView is wrapped in ScrollViewer with HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" properties set.
3. RadGridView is bound to an empty itemsource
4. RadGridView's property ColumnsWidthMode =Fill

The fix will be available in our latest internal build(this Friday). But we still cannot be sure if this fix will fix the issues you have. That's why it would be best if it is possible to send us a small example where we can reproduce the problem.

Sincerely yours,

I am getting the same error after upgrading to SP1. I have a complicated setup however. I am using the hierarchical child grids. 

My error is:'-2' is not a valid value for property 'ViewportSize'.

The disassembly shows that the error occurs in

c:\Builds\WPF_Scrum\GridView_WPF_2009_Q2_SP1\Sources\Development\Controls\GridView\GridView\GridView\Virtualization\GridViewScrollViewer.cs
