RowSelectorHeaderUIElement in OutlookGroupedBy ViewStyleBand
posted

Does anyone know how can I find out what the child rows are (or their parent row) when the row selector element in a group is clicked? I have used the AfterRowExpanded event successfully to get the parent row, but if several groups are already expanded and the user returns to a previously expanded group to click the row selector, I don't then parent row is the wrong one.

(The reason for this is that I want to select all of the rows within the OutlookGroup with one mouse-click for subsequent copy/paste/Excel export/etc.)

A screen-shot is attached.

Thanks in advance,

Richard

                // If we still haven't found a RowSelectorHeaderUIElement by now, just exit.

                // Clear any existing selection.
                grid.Selected.Rows.Clear();

                // If there are rows in the list, select them all.
