Grouped columns should be sortable and group sorts should be sorted before the columns.
When hiding grouped columns and you drag a sorted column to be grouped, the ability to sort it disappears.
Also if column is the second sort, the first sort causing the groups to sort wrong.
When removing a grouped & sorted column, the column should probably become the first sort.
Hi @JohnRobinson,
Not sure I understand the request. At the moment grouping will take into account column sort direction. For example:
You can also specify sort direction when adding GroupDescriptor programmatically:
Apply the changes below in DataGridGroupHeaderTemplatePage.razor.
Note that Callahan shows up as the first group, and only has 2 entries, instead of 104.
Remove the Employee grouping and add it back.
Note that Buchanan now shows up first now.
In DataGridGroupHeaderTemplatePage.razor, add these properties to the data grid:
ShowMultiColumnSortingIndex=true AllowMultiColumnSorting=true HideGroupedColumn=true
Replace the OnRender with:
void OnRender(DataGridRenderEventArgs<Order> args)
{
if(args.FirstRender)
{
args.Grid.OrderByDescending("OrderDate");
args.Grid.OrderBy("Employee.LastName");
args.Grid.Groups.Add(new GroupDescriptor(){ Title = "Employee", Property = "Employee.LastName"});
StateHasChanged();
}
}
