After searching for a MultiColumn ComboBox with configurable view columns, configurable display & value members, I decided to create my own control.
The Multi-Column ComboBox is a combination of TextBox, Button & DataGridView control. Since I had a need to create a control like a ComboBox and with search functionality, I decided to use DataGridView & it's filter criteria for fast search functionality.
One of the harder things to figure out was what container to show on key press of the combo control. I used ToolStripDropDown as a host control for DataGridView to show the ComboBox popup on key press.
Common Properties:
- Show Header: Set column header visibility.
- Grid Lines: Set grid lines as None, Vertical, Horizontal or Both.
- DropDown Height: Configurable dropdown height. It will show scrollbar if more items present.
- DataSource: DataSource will be a DataTable.
- SourceDataString: Mapping Properties which will be shown as Columns.
- SourceDataHeader: Column Headers which will be shown if Show Header property is true.
- ColumnWidth: Width for each column.
- Display Column No: Column number which will be work as a DisplayMember.
- Value Column No: Column number which will be work as a ValueMember.

Clean code. But, there appear to be a couple of problems (missing some common combobox features). 1) No mouse hover which auto hilights the line the mouse is over 2) After user selects an item, all items in the list dissapear except for the one selected.
