Ok, not sure why I don't. I updated it in january. How do i upgrade my current version?

Hi,

You need build number  9.2.20092.1065 or above. That's the build that is shipped with the SR I mentioned above.

So, you would need to apply tha latest SR (available at our site) in order to have this issue fixed.

HTH,

I have version 9.2.20092.1007.

I just tested this and it the cell control attach still does not work for any cell in columns that i create with the following loop:

 while (currentDate <= finishDate)

            {

                var tc = new TemplateColumn();

                tc.HorizontalContentAlignment = HorizontalAlignment.Left;

                tc.VerticalContentAlignment = VerticalAlignment.Top;

                tc.ItemTemplate = (DataTemplate)Resources["myCellTemplate"];

                //var tc = (TemplateColumn)Resources["TemplateColumn"];

                tc.HeaderText = currentDate.Value.ToString("ddd\nMM/dd");

                tc.Tag = currentDate.Value.ToString("yyyy/MM/dd");

                tc.HorizontalContentAlignment = System.Windows.HorizontalAlignment.Center;

                //tc.HeaderStyle = App.Current.Resources["HeaderCellControlStyle1"] as Style;

                tc.CellStyle = Application.Current.Resources["RedStyle"] as Style;

                tc.Key = "day" + count++;

                TaxonomyGrid.Columns.Add(tc);

                currentDate = currentDate.Value.AddDays(1);
