I just upgraded my project with the lastest DLL's of Q1 2010 version.
I have a view with a RadGridView control displaying a custom object, with the custom columns defined.
The definition of the columns is something like this:
<
TelerikControls:RadGridView.Columns>
<TelerikControls:GridViewSelectColumn Header="" />
<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding CodigoAbonado}" Header="{DynamicResource LBL_AccionComercialView_CodigoAbonado}" IsReadOnly="True" IsFilterable="False"/>
<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding CodigoPostal}" Header="{StaticResource LBL_AccionComercialView_CodigoPostal}" IsReadOnly="True" IsFilterable="False"/>
<TelerikControls:GridViewDataColumn Width="Auto" DataMemberBinding="{Binding CuentaNombre}" Header="{DynamicResource LBL_AccionComercialView_NombreCuenta}" IsReadOnly="True" IsFilterable="False"/>
<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding IdFranquicia}" Header="{DynamicResource LBL_AccionComercialView_Franquicia}" IsReadOnly="True" IsFilterable="False"/>
<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding Envios}" Header="{DynamicResource LBL_AccionComercialView_NumeroEnvios}" IsReadOnly="True" IsFilterable="False"/>
<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding Facturacion}" Header="{DynamicResource LBL_AccionComercialView_Facturacion}" IsReadOnly="True" IsFilterable="False"/>
</TelerikControls:RadGridView.Columns>
where "TelerikControls" is
xmlns:TelerikControls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
The application crashed with the following error:
"Null object reference exception.

Any idea of what's happening?
Is version Q1 2010 not stable for this control?
Thanks in advance.

Thank you for your feedback. The error is caused by a bug that was recently reported by another customer. The problem is fixed and our next internal build will include a patched version of the control. I apologize for any injconveniences this may have caused you.
