Multiple grouping hiding detail data

[Dan Martin]

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

Vlad,  I upgraded to build 813 but it did not solve the problem.  As before, grouping by a single column is fine, but when I add a second column, I lose visibility of everything except the first subgroup and, when expanded, the first row of data. 

Thanks,
Dan
