UI not updated when grouping gridview in WPF

Question

Xaml for dynamic grid

<telerik:RadGridView Name="RadgridHoover"
                                 CanUserDeleteRows="True"
                                 CanUserInsertRows="True"
                                 ShowColumnHeaders="True"
                                 ShowGroupPanel="{Binding IsShowGroupPanel, Mode=TwoWay}"
                                 AlternateRowBackground="Transparent"
                                 AlternationCount="2"
                                 AutoGenerateColumns="False" 
                                 SelectionMode="Multiple"
                                 IsReadOnly="True"  
                                 IsFilteringAllowed="True"
                                 EditTriggers="CurrentCellClick"
                                 SelectionUnit="FullRow"
                                 EnableColumnVirtualization="False"
                                 EnableRowVirtualization="True"
                                 RowIndicatorVisibility="Collapsed"
                                 GridLinesVisibility="Horizontal"
                                 behaviors:GridColumnsBindingBehavior.Columns="{Binding Columns, Mode=TwoWay}" 
                                 ItemsSource="{Binding MembersTable, Mode=TwoWay}"
                                 SelectedItem="{Binding SelectedItem}"
                                 DataLoadMode="Asynchronous"
                                 >
        </telerik:RadGridView>

When grouping data on grid, expand a header group and select a record to edit this selected record. After that, I updated data row on grid for selected record in viewmodel:

public void UpdateRow(int index, object data)
    {
        if (data != null)
        {
            var row = MembersTable.Rows[index];
            for (int i = 0; i < data.GetType().GetProperties().Count(); i++)
            {
                PropertyInfo pinfo = data.GetType().GetProperties()[i];
                if (!ListPropertiesName.Contains(pinfo.Name))
                {
                    row[pinfo.Name] = pinfo.GetValue(data, null);
                }
            }
            MembersTable.Rows[index] = row;
        }
    }

This selected row is not updated, just when i scroll the grid, this selected row is updated. If not grouping row, everything is okay.

Please help me this case.
Thanks a lot.

For more than the past 2 years DataLoadMode="Asynchronous" for RadGridView is not recommended by telerik guys. Looks like they themself have broken the feature in new releases.

If you are OK for changing DataLoadMode to something other than Asynchronous the issue might get resolved.
