Hi,

I have seen some problems in using the pivot grid and I can reproduce it with the sample code coming with WPF DV 2010 v2 feature browser.

The changes I made to the sample code:

1. Add a button in FlatDataSource (XAML) xaml file which is DataSourceFlatDataXAML.xaml:

        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition Width="Auto" />
           <ColumnDefinition />
        </Grid.ColumnDefinitions>

        <igPivot:XamPivotGrid x:Name="pivotGrid" DataSource="{StaticResource FlatDataSource}" />

        <igPivot:Expander Grid.Column="1">
            <igPivot:XamPivotDataSelector x:Name="dataSelector" DataSource="{StaticResource FlatDataSource}"  />
        </igPivot:Expander>
      <WrapPanel Grid.Column="2">
        <Button Name="Invoke" Content="Refresh" Click="Invoke_Click"/>
      </WrapPanel>

2. Add Invoke_Click method in DataSourceFlatDataXAML.cs:

      private void Invoke_Click(object sender, System.Windows.RoutedEventArgs e) {
        (this.pivotGrid.DataSource as FlatDataSource).ItemsSource = SampleDataGenerator.GenerateSales(500);
      }

When I run the modified app, the FlatDataSource (XAML) sample displays correctly on initial load, but not after I click "Refresh" button. The cube display is gone.

I wonder if there's a simple setting to re-initialize the state, but haven't found any in the documentation.

Please help.

Thanks,

Yu
