TreeList does not show a calendar to filter a DateTime column

created 9 years ago

I am trying to have a tree list show the calendar control for filtering data but it does not seem to work.
Please see the attached code file.

I am setting

treeList1.OptionsBehavior.EnableFiltering = true;
            treeList1.OptionsFilter.FilterMode = DevExpress.XtraTreeList.FilterMode.Smart;

treeList1.Columns["Time"].Format.FormatType = DevExpress.Utils.FormatType.DateTime;
            treeList1.Columns["Time"].OptionsFilter.FilterPopupMode = DevExpress.XtraTreeList.FilterPopupMode.Date;
            treeList1.Columns["Time"].OptionsFilter.AllowFilter = true;

What am I doing wrong? I have tried many different combinations for FilterMode etc, but the drop down only is able to show either the List or Checked List of distinct times.

Please advise…

    Hello, We're currently using Devexpress 14.1.8 and facing this issue. Is this issue also problematically on 14.1.8?

      Hi Elmar,

      Yes, this behavior is fixed in v15.1.8. Previous versions contain this issue. Thus, I recommend you update your project (I see that v18.1 available to you).

      Should you have further questions, let me know.

        Hi Neil, It seems to be an issue in TreeList. I've forwarded this ticket to our developers so they can address this issue. We'll reply here once we have any results.
