Using VB in VS2008 with WPF 2009 Q2 Build 724.35. The problem also showed up using Build 701.
With Build 701, when I added the second group, I got an exception in Telerik.Windows.Data with message
"Specified argument was out of the range of valid values. Parameter name: position"
With Build 724, the exception is gone, but when grouping by two fields, either run-time or programatically, only the first data record (or the first group) is visible in the grid.

Here is the code defining the data for the grid:

    
            Dim dsBudget As New BudgetDataSet   
        
            Dim taDetails As New BudgetDataSetTableAdapters.DetailsTableAdapter   
        
            taDetails.Fill(dsBudget.Details)  
        
            RadGridView1.ItemsSource = dsBudget.Details.DefaultView

Here is one simple variant of the XAML files I have used(autogenerating the columns still has the same problem):

    
            <Grid>    
        
              <Grid:RadGridView Name="RadGridView1"   
        
                AutoGenerateColumns="False" >   
        
                <Grid:RadGridView.Columns>   
        
                  <Grid:GridViewDataColumn HeaderText="Category"   
        
                    DataMemberBinding="{Binding Path=Category}" >   
        
                  </Grid:GridViewDataColumn>   
        
                <Grid:GridViewDataColumn HeaderText="Company"   
        
                    DataMemberBinding="{Binding Path=Company}" >   
        
                </Grid:GridViewDataColumn>   
        
                <Grid:GridViewDataColumn HeaderText="Amount"   
        
                    DataMemberBinding="{Binding Path=Amount}"   
        
                    DataFormatString="{}{0:f2}" >   
        
                </Grid:GridViewDataColumn>   
        
                <Grid:GridViewDataColumn HeaderText="Description"   
        
                    DataMemberPath="Description" >   
        
                </Grid:GridViewDataColumn>   
        
                </Grid:RadGridView.Columns>   
        
              </Grid:RadGridView>   
        
            </Grid>

Any insight will be greatly appreciated.

Thanks, Dan
