1425

Hi,

I am grouping a DateTime column and I am using GroupByMode = FieldGroupByMode.Date. But the problem is it gets grouped with min date.

I then formatted the date in GroupByRecordPresenter_Loaded event. It then looked fine. Like follows:

But then if there is a column already grouped lets say column 'A' and I group my DateTime column after that and then I remove column 'A' from group pane, group header description of my Datetime column again gets the minimum datetime like follows:

Will be grateful for your help.

Thanks,

Imad.

Hi Stefan,

The problem is solved. It was due to converter that I was using. Following 2 lines in the code that I posted above:
f.Converter = _MyDateTranslator;
f.ConverterParameter = f.Name;

I am not using these any more and its displaying datetime in group header correctly.

Thanks.

Imad.

Hello Imad,

I have been looking into the screenshot and the code you have provided, but it seems like I am missing something about your scenario, so could you please send me an isolated sample project, where this is reproduced, so I can investigate it further for you.

Looking forward for your reply.

Hi Stefan/ Andrew,

Infact the actual problem is differen to what I realized initially.

I am using GroupByMode = FieldGroupByMode.Date but its grouping all items in one group instead of separate group of dates.

Here is how I am creating my field:

f.Converter = _MyDateTranslator;
f.ConverterParameter = f.Name;
f.Settings.LabelTextAlignment = TextAlignment.Center;
f.Settings.CellVisibilityWhenGrouped = Visibility.Collapsed;
f.DataType = typeof(DateTime);
f.Settings.EditorType = typeof(XamDateTimeEditor);
f.Settings.EditorStyle = new Style(typeof(XamDateTimeEditor));
f.Settings.EditorStyle.Setters.Add(new Setter(XamDateTimeEditor.FormatProperty, "G"));
f.Settings.SortComparer = new MyDateTimeComparer();
f.Settings.AllowGroupBy = true;
f.Settings.Width = FieldLength.Auto;
f.Settings.GroupByMode = FieldGroupByMode.Date;

I am missing anything here?

waiting for your reply.

Thanks,

Imad.
