UnhandledException when InitializeRecordEvent set record visibility to collapsed
posted

If I set the DataRecord to Collasped in a InitializeRecordEvent handler I will get intermittent hidden records and  UnhandledExceptions at the application level when scrolling the window. Has anyone seen this?

I am using 9.1.

/*****************Handler**************/

   private void PlanGridRecordInit(object sender, InitializeRecordEventArgs e)
        {
            DataRecord rec = e.Record as DataRecord;
            Infragistics.Windows.DataPresenter.CellCollection cells = rec.Cells;
            double RelNo = double.Parse(cells["RelNo"].Value.ToString());
           
            if (currentRelease != 0&& RelNo != currentRelease)
                rec.Visibility = Visibility.Collapsed;
            else
                rec.Visibility = Visibility.Visible;

        }

    I haven't seen that issue. Have you tried testing this with the latest hotfix? Also would it be possible to post the callstack of the exception you are seeing?
