WPF DataGrid：禁用多列选择

Question

我试图阻止用户通过挂钩到DataGrid的SelectedCellsChanged事件来对多个列进行单元格选择。

出于某种原因，我的代码表现得有些奇怪。

这是我的代码：

private void chartDataGrid_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
    foreach (DataGridCellInfo cell in e.AddedCells)
    {
        // If a selected cell is within a different column than the first selected cell, undo the selection (to prevent selections from crossing multiple columns)
        if (cell.Column != e.AddedCells[0].Column)
                    this.chartDataGrid.SelectedCells.Remove(cell);
    }
}

谁能告诉我这里缺少什么？

Answer 1

好的，我摆脱了这种行为，但偶然发现了新代码的另一个问题，如下所示：

private void chartDataGrid_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
    foreach (DataGridCellInfo cell in e.AddedCells)
    {
        // If a selected cell is within a different column than the first selected cell, undo the selection (to prevent selections from crossing multiple columns)
        if (cell.Column != this.chartDataGrid.SelectedCell[0].Column)
            this.chartDataGrid.SelectedCells.Remove(cell);
    }
}

现在我无法将我的选择扩展到右侧的列（这很好），但我仍然可以在左侧。
