Thank You for your reply Stefan. My code is exactly like yours, so couldn't figure out what was wrong until now. All I had to do was wrap the code in DrillIn in a Dispatcher delegate and it all worked like charm.

Hello Sangeetha,

Thank you for your post. I have been looking through it and I created a sample project for you with the functionality you want. Basically used the code from the Feature Browser and add a comment in the Click event of the Expand button where you should make some changes depending on your data. Please let me know if this helps you or you need further assistance.

Looking Forward for your reply.

Hi Petar,

Thanks for your reply. I tried your sugestion but unfortunately could not get it to work.

I tried the approach in the link below - it doesn't always expand all hierarchies either.

http://samples.infragistics.com/sldv/RunSamples.aspx?cn=pivot-grid#/pivot-grid/expand-hierarchies

Here is my code. If you see any inconsistencies/errors please let me know.

private void ExpandAll_Click(object sender, RoutedEventArgs e)

{

BackgroundWorker worker = new BackgroundWorker();
                worker.DoWork += Worker_DoWork;
                worker.RunWorkerCompleted += (s, ee) =>
                {
                    this.pivotGrid.DataSource.DeferredLayoutUpdate = false;
                };
                this.pivotGrid.DataSource.DeferredLayoutUpdate = true;
                worker.RunWorkerAsync(this.pivotGrid.DataSource);

}

ManualResetEvent manualResetEvent = new ManualResetEvent(false);
        void Worker_DoWork(object sender, DoWorkEventArgs e)
        {
            DataSourceBase dataSource = e.Argument as DataSourceBase;

            if (dataSource.Rows.Count > 0)
            {
                IFilterViewModel fvm = dataSource.Rows[0] as IFilterViewModel;
                if (fvm != null)
                {
                    fvm.LoadFilterMembersCompleted += (sender1, e1) =>
                    {
                        manualResetEvent.Set();
                    };

                    if (fvm != null && fvm.FilterMembers != null)
                    {
                        foreach (IFilterMember member in fvm.FilterMembers)
                        {
                            DrillIn(fvm, member);
                        }
                    }
                }
            }
        }

        private void DrillIn(IFilterViewModel filterViewModel, IFilterMember filterMember)
        {
            manualResetEvent = new ManualResetEvent(false);

            this.Dispatcher.BeginInvoke((Action)delegate()
            {
                filterMember.IsExpanded = true;
            });

            if (filterMember.HasChildren && filterMember.FilterMembers.Count == 0)
                manualResetEvent.WaitOne();

            foreach (IFilterMember member in filterMember.FilterMembers)
            {
                DrillIn(filterViewModel, member);
            }

        }

Thanks
