I would like to be bale to modify at once several cells of a GridViewComboBoxColumn, when using the common ItemsSourceBinding for all rows (in my GridView, the selection is: SelectionMode="Multiple" SelectionUnit="FullRow"). So I would like for the selected rows to apply the same value as the edited cell.
Hello Christophe, In general, I suggest you implementing such requirement on data level and use the binding mechanism that GridViewComboBoxColumn supports. If further assistance is needed, feel free to open a new support ticket and describe your requirements in it. All the best.
Maybe this principle should be extend to other types also. We have another need, when we would like to apply same date as the current edited one to all selected rows.
