SelectedItem set to null on DC-Change

[Martin]

Dear Support,

using the RadGridView inside a DataTemplate, the bound SelectedItem becomes null in the first VM
after changing the VM to a second, different, VM of the same type.

  <ContentPresenter Content="{Binding CurrentContentViewModel}">

            <ContentPresenter.Resources>

                <ResourceDictionary>

                    <DataTemplate DataType="{x:Type local:ContentViewModel}">

                        <telerik:RadGridView ItemsSource="{Binding Items}"

                                             SelectedItem="{Binding SelectedItem}" />

                        <!--<ListView ItemsSource="{Binding Items}"

                                  SelectedItem="{Binding SelectedItem}" />-->

                    </DataTemplate>

                </ResourceDictionary>

            </ContentPresenter.Resources>

        </ContentPresenter>


Alternatively i tried ListView, which behaves as expected.

Is this a bug or am I doing wrong?

Find here a solution that reproduces this behaviour.

Hi Martin,

I admit that there is a different behavior compared to DataGrid, but unfortunately in order to support some features (as grouping) we need to clear SelectedItem when data source is changed.
