Hi Josip Jaic,

Which version of Ria Services is used in your project? Is it the latest one (WCF Ria Services beta)? If not, could you please to download the latest release and try again.

Hi,

I have migrated project to WCF RIA Beta,
and it works ok with  Telerik 2009.3.1201.1030

but when i put Telerik 2009.3.1211.1030
or Telerik 2009.3.1208.1030

i got same exception (see previous post)

Hi,

I have done some additional tests.

On   Loader _Completed method of my context if i put return like this:

return

 

;  

 

 

QueryableCollectionView view = new QueryableCollectionView ( ctxZadatak.Zadataks );

rgvZadaci.ItemsSource = view;

now it doesnt crash  (of course it does not load grid)

But  if i put return like this. it throws error:

 

 

 

 

 

 

QueryableCollectionView view = new QueryableCollectionView ( ctxZadatak.Zadataks );

rgvZadaci.ItemsSource = view;

return

 

;


So i have replaced 

 

 

 

QueryableCollectionView view = new QueryableCollectionView ( ctxZadatak.Zadataks );

rgvZadaci.ItemsSource = view;

 

 

with :

 

rgvZadaci.ItemsSource = ctxZadatak.Zadataks;

 

 

and now it works OK, but i dont have pager... and it works very slow.....

here is my xaml

 

 

 

 

<data:DataPager HorizontalContentAlignment="Left" Source="{Binding ItemsSource, ElementName=rgvZadaci}" Grid.Row="0" Grid.Column="1" PageSize="{Binding ElementName=txtPageSize, Path=Value, Mode=TwoWay}" IsTotalItemCountFixed="False" Margin="10,10,10,5" DisplayMode="FirstLastPreviousNextNumeric" />

Hello Josip Jaic,

When the grid is inside ScrollViewer or StackPanel will be measured with infinity height which will cause serious performance problems since there will be no virtualization and all rows will be created at once.

Hi Vlad,

 

I have removed scrollviewer as you said, and
i am now using RadControls_for_Silverlight_2009_3_1219_Dev

It works OK now,

Thank you
