Hello,

i have a component that contains a Telerik Grid and a Planning component,  if i grouped the rows of telerik grid, then the rows of the planning are grouped.

for grouping the rows of the planning, i use the grouped event of the Telerik Grid for begin the grouping in the planning  and, i use Property Groups(CollectionViewGroup) to get the sort of the rows, this is ok!!

Now, i want do the same thing, but using the option sort by group, but i'm using InvertGroupSortDirectionRequested,  the property Groups is not yet sorted.

Can you help me.

Thanks

Hello Guillermo Aquino,

 InvertGroupSortDirectionRequested fires just before the sorting state of a GroupDescriptor changes. You can access the GroupDescriptor that fired the event like so:

GroupDescriptor groupDescriptor = (GroupDescriptor) e.GroupCell.DataContext;

You can get the current sort direction from the SortDirection property. If the current SortDirection is Ascending, after the event fires it will be Descending. If it is Descending, it will be null. If it's currently null, it will be Ascending and so on.

This way you will know that the new sort direction will be so that you can sort the groups in your Planning control.
