Hello
I have a couple of questions regarding XamPivotGrid and FlatDataSource.
1.
I have a HierarchyDescriptor with a month:
dateTimeDataDescriptor.AddLevel<DateTime>(date => date.ToString("MMM", CultureInfo.CurrentCulture), "Months" );
It will give me the months like: jan, feb, mar, etc. The problem is when I sort, which will be sorted alphabetically. This is not correct in this case as you would expect jan to be first. Is there any way to control this?
2.
How do I set the default sorting to ASC. Whenever I add a row or a column I would like it to be sorted.
Hello,
The ResultChanged event fires when a slice is changed and could be used to apply a sorting logic after an update. You can review the Events for IOlapViewModel section at http://www.infragistics.com/help/wpf/xampivotgrid-handlingevents for additional details.
If you have other questions, do not hesitate to ask.
Both solutions works fine.
But regarding the sorting, the PivotGrid is pretty dynamic in my case. The user will add rows and columns from different sources. This means my [DimensionName] is very much dynamic and I dont know it.
The behaviour I am looking for is that all rows/colums is sorted acs by default. If the user change the sorting this should not be overwrited when calling LoadCustomazations() or RefresgGrid().
Do you have any suggestion on which event I could apply the sorting?
Hope my explanation makes sence :)
Hello,The OrderByKeyExpression property should be set to an expression in order to sort a hierarchy descriptor.
Expression<Func> orderByExpression = d => d.Date.Month; datesHierarchy.LevelDescriptors[0].OrderByKeyExpression = orderByExpression;
You can add LevelSortDirections to the FlatDataSource. LevelDefaultSortDirections list in order to sort the FlatDataSorce in code.
LevelSortDirection sortDirection = new LevelSortDirection();sortDirection.LevelUniqueName = "[DimensionName].[HierarchyName].[ LevelName]";sortDirection.SortDirection = ListSortDirection.Ascending;dataSource.LevelDefaultSortDirections.Add(sortDirection);
