MSJO.kr이번 글은 WPF Datagrid를 사용할 때 선택한 Row에서 각 Column 값을 가져오는 예제이다. 아래 소스는 클래스 모델(Database라고 가정)을 그리드에 바인딩하고 Cell 안의 버튼 이벤트와 Row 선택 이벤트를 어떻게 작성하는지 보여준다.

public int ID { get; set; }
public string Name { get; set; }
public static ObservableCollection<Student> GetStudent()

var student = new ObservableCollection<Student>
{
new Student() { ID = 100, Name = "가나닭-abc" },
new Student() { ID = 200, Name = "마바삵-ABC" }
};
return student;
}
}

WPF DataGrid - Selection Mode
- SelectionMode = “Single/Extended”
- SelectionUnit = “Cell/FullRow(Default)/CellOrRowHeader”
- Methods : SelectAll(), UnselectAll(), SelectAllCells(), UnselectAllCells()
- Options : SelectedItem, SelectedItems, SelectedCells
