Hello Carlos Teevin,
There are some known issues concerning custom grouping
in the current version of RadGridVew.
You can use a work around this by adding a hidden (isVisivle = false) column and populate it with integer values corresponding to the days in the GridViewDateTimeColumn
. Then you can use the GroupByExpressions CollectionChanged
event to replace the grouping expression of your DateTime column with an expression for your hidden column:
sender, NotifyCollectionChangedEventArgs e)
(index >= 0)
"[HiddenColumn] Group By [HiddenColumn]"
We are working on removing the custom grouping issues for the next versions of RadGridView.
