Dear Sir/Madam
I have an ultrawingrid that has three columns.
ID Name Surname
I can drag one of the columns to the brand, or even two or three and then group them together with Outlook’s property
What I need is to group them by the item number, in ascending or descending order with just one column, two or three (as that choice will be depending on the user)
Looking forward to hearing from you.
I need tha event because the columns groups is dinamics and order by des or asc for items count
Sorry but I don't understand your request. You can programmatically group by columns using the UltraGrid.DisplayLayout.Bands[n].SortedColumns collection; this collection exposes an Add method which takes the column to be sorted, its sort order, and also whether the column should be grouped.
If you are familiar with all this and want to group the columns in some kind of non-standard way, you can use the IGroupByEvaluator interface (see UltraGridColumn.GroupByEvaluator property) to control which groups a given row is added to.
