WPF 数据网格 : SelectionChanged event isn't raised when SelectionUnit ="Cell"

Question

我正在使用 WPF 工具包数据网格。我已将其设置为 SelectionUnit="单元格"和 SelectionMode="扩展" .

永远不会引发 SelectionChanged 事件!

当 SelectionUnit 设置为 FullRow 时，它工作正常。

我错过了什么吗？

顺便说一句，我需要它的原因是因为我试图创建一个附加属性来帮助我将 SelectedCells 绑定(bind)到我的 ViewModel。

使用DataGrid.SelectedCellsChanged应该provide you用你需要的东西。

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();

    }
}
