Datagrid上的WPF MouseDown =＆gt;获取列和行

Question

如何识别我点击DataGrid的位置？

<DataGrid x:Name="TheGrid" SelectionMode="Single" SelectionUnit="Cell" MouseDown="CellClick">

private void CellClick(object sender, MouseButtonEventArgs e)
{
    foreach (DataGridCellInfo cell in TheGrid.SelectedCells)
    {
        MessageBox.Show(TheGrid.Items.IndexOf(cell.Item).ToString());
    }
}

非常感谢

您可以像这样处理SelectedCellsChanged事件：

private void TheGrid_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
    if (TheGrid.SelectedCells.Count > 0)
    {
        DataGridCellInfo dgci = TheGrid.SelectedCells[0];
        int columnIndex = dgci.Column.DisplayIndex;
        DataGridRow row = TheGrid.ItemContainerGenerator.ContainerFromItem(dgci.Item) as DataGridRow;
        int rowIndex = row.GetIndex();

        MessageBox.Show($"Row {rowIndex} Column {columnIndex}");

    }
}

将在MouseUp上选择一个单元格。要在此事件发生之前获取单元格，您必须在Datagrid上侦听MouseDown并使用VisualTreeHelper.HitTest检查鼠标下的哪个元素。
