Sorted RadGridView edit issue in MVVM

[Alic W]

I have a GridView and use MVVM pattern, I bind SelectedItem to an object in my viewmodel, and on row edit ended pass this as a parameter to my insert method, as described in Telerik documentation here:

http://www.telerik.com/help/wpf/patterns-and-practices-eventtocommand-mvvmlight.html

Namely:

<telerik:RadGridView x:Name="xRadGridView" ItemsSource="{Binding GridItems, Mode=TwoWay}">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="RowEditEnded">
               <i:InvokeCommandAction Command="{Binding TestCommand, Mode=OneWay}"
                              CommandParameter="{Binding ElementName=xRadGridView, Path=SelectedItem}"/>
            </i:EventTrigger>
        </i:Interaction.Triggers>
</telerik:RadGridView>

Here's the problem - when I first sort the grid by some field and then add a new item, the SelectedItem property on RowEditEnded event is set to an item that was the last item in the list prior to insert. 

For example, I have a field SequenceNumber and sort the grid in descending order. When I insert an item, the field is blank; I then enter a very high value that would place the item to the top of the list; however, the SelectedItem parameter has the value of the last item in the list (which would be the case if no sort was initially performed). Is this a known issue? Please help.

I am using RadControls for WPF Q2 2012 SP1 by the way. If it was a known issue that got fixed, were any work-arounds known?

Hi,

The SelectedItem property holds the item you have selected, not the last item that has been inserted. No matter if you sort or not, the SelectedItem should remain the same until you select another item.

Is it not that way in your solution? Would you please share some more information on what would be the expected result for your case?
