Please recommend some Multi-Column ComboBox control for Winforms application in .net. Better if they are free.
I found Syncfusion - Multi-column-combo-box it can show datagrid which is bound to datasource but it is not free.
EDIT: There is an awesome control used in inFlow Inventroy, please also tell if you know something like this
Controls from other answers and those which I found myself
DevExpress - GridLookUpEdit
