The program I'm working on presents a list of customers in a grid, in sorted order. Because the list is getting rather large (about 2,650 customers at last count), I'd like to start grouping it as well, by the first character of the customer name.
I've given it appropriate GroupColumnDescription and SortColumnDescription definitions in my .xaml file:
<sync:SfDataGrid.GroupColumnDescriptions>
<sync:GroupColumnDescription ColumnName="CustomerName" Converter="{StaticResource customerListItemConverter}" />
</sync:SfDataGrid.GroupColumnDescriptions>
<sync:SfDataGrid.SortColumnDescriptions>
<sync:SortColumnDescription ColumnName="CustomerName" SortDirection="Ascending" />
</sync:SfDataGrid.SortColumnDescriptions>
Given these definitions, I would expect to see the list of groups in sorted order, and within each group, to see the customers in that group,
also in sorted order. What I get... well, that's a different matter. The order of the groupings is as expected; the order of the customers within each group is
not.
For example, under "3", I would expect to see customers listed in this order:
Instead, I get this:
The Interval Grouping sample was unfortunately not helpful, as it exhibits similar behavior (it's ostensibly sorted in ascending order by shipped date, but the dates go from 1991-05-15 to 1991-05-23, then back to 1991-05-17).
Is there any way to get this to happen?
