WPF MultiColumn Combo
The Multi-Column Combo acts just like a grid - automatically generating columns for every property on the data object that is contained in the IEnumerable that is set on the control's ItemsSource property.
Use the control's Footer property to specify content that should appear in the Footer area of the dropdown.
Control how the dropdown list is filtered as the user types text into the control's text area.
Enable single or multiple selection as well as reset the currently selected items.
Text, Checkbox, Image and Date column support.
Embed in Grid
