GridView throwing exception when scrolling

[Ivan Moura]

I have a GridView like this:

<telerikDocking:RadPaneGroup
                    VerticalAlignment="Stretch"
                    HorizontalAlignment="Stretch"
                    d:IsHidden="True"
                    MinHeight="300" >
                    <telerikDocking:RadPane Header="Propriedades"
                                            CanUserClose="False"
                                            CanDockInDocumentHost="False"
                                            CanUserPin="False"
                                            CanFloat="False"
                                            IsPinned="True"
                                            IsSelected="True" >
                           <telerik:RadGridView x:Name="propertyGridView"  />
                    </telerikDocking:RadPane>
</telerikDocking:RadPaneGroup>

 And when I try to vertically scroll the Grid it throws a Exception:

Any Ideas on what is causing this error and  how to resolve this Issue? Thanks in advance.

Hello Ivan Moura,

I have tried to reproduce the exception using your code snippet but everything worked fine on my end. Please, take a look at this short video and let me know if I have missed something. It will be great to send us a sample project or to give us some more details about your scenario.

Best wishes,
