If the above suggestion helped you solve your issue please verify the thread as answered so other users may take better advantage of it.

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

I would like to know your solutiion if possible.

Hi,

I got this working by using a delegate around the line I set expand/collase once I upgraded to V11.2

Thanks

Hi Stefan,

Thank You for your immediate reply.

Yes the solution works fine. There is one small problem though - I don't see any suitable place to turn the expand boolean off - I want to expand only when ExpandAll button is clicked, and not when just layout is updated. What would you suggest as a good place to turn this off.

Also, I would like to have a bug report created for the Background worker exception.

Thanks

Hello Sangeetha,

I tried the sample with the latest service release and everything was as you said, so I modified it by using a different logic to expand all cells, this time without BackgroundWorker, so now it works as expected.

Hope this helps.

Hi Stefan,

I updated my WPF to the latest Service Release 2094, and noticed that the Expand/Collapse code won't work anymore - I think Background worker has a bug in it. I just ran your sample and I see the same exception. Could you please investigate and let me know if it is a bug or some functionality changed.

Thanks

Sangeetha
