예제

다음 예제에서는 이벤트를 처리 SelectedCellsChanged 하고 새로 선택한 셀의 값을 지우는 방법을 보여줍니다.

<Grid>
    <DataGrid Name="DG1" ItemsSource="{Binding}" SelectionUnit="CellOrRowHeader" SelectionChanged="DG1_SelectionChanged" SelectedCellsChanged="DG1_SelectedCellsChanged" />
</Grid>

private void DG1_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
    //Get the newly selected cells
    IList<DataGridCellInfo> selectedcells = e.AddedCells;

    //Get the value of each newly selected cell
    foreach (DataGridCellInfo di in selectedcells)
    {
        //Cast the DataGridCellInfo.Item to the source object type
        //In this case the ItemsSource is a DataTable and individual items are DataRows
        DataRowView dvr = (DataRowView)di.Item;

        //Clear values for all newly selected cells
        AdventureWorksLT2008DataSet.CustomerRow cr = (AdventureWorksLT2008DataSet.CustomerRow)dvr.Row;
        cr.BeginEdit();
        cr.SetField(di.Column.DisplayIndex, "");
        cr.EndEdit();
    }
}

Private Sub DG1_SelectedCellsChanged(sender As Object, e As SelectedCellsChangedEventArgs)
    'Get the newly selected cells
    Dim selectedcells As IList(Of DataGridCellInfo) = e.AddedCells

    'Get the value of each newly selected cell
    For Each di As DataGridCellInfo In selectedcells
        'Cast the DataGridCellInfo.Item to the source object type
        'In this case the ItemsSource is a DataTable and individual items are DataRows
        Dim dvr As DataRowView = DirectCast(di.Item, DataRowView)

        'Clear values for all newly selected cells
        Dim cr As AdventureWorksLT2008DataSet.CustomerRow = DirectCast(dvr.Row, AdventureWorksLT2008DataSet.CustomerRow)
        cr.BeginEdit()
        cr.SetField(di.Column.DisplayIndex, "")

        cr.EndEdit()
    Next
