获取DataGrid中特定单元格的值

我有一个DataGrid。现在我想用一个特定单元格的数据来做比较。为此，我找到了那个细胞的rowindex。我需要第二列的数据。到目前为止，我在datagrid的KeyDown事件中的代码如下所示:

DependencyObject dep = (DependencyObject)e.OriginalSource;
while ((dep != null) && !(dep is DataGridCell) && !(dep is DataGridColumnHeader))
{
    dep = VisualTreeHelper.GetParent(dep);
}
if (dep == null)
    return;
if (dep is DataGridCell)
{
    //cancel if datagrid in edit mode
    maindg.CancelEdit();

    //Check if selected cell is on second column and last row
    if (maindg.CurrentColumn.DisplayIndex == 1)
    {
        DependencyObject depObj = dep;
        //Find Row to which selectedCell belongs
        while ((depObj != null) && !(depObj is DataGridRow))
        {
            depObj = VisualTreeHelper.GetParent(depObj);
        }
        DataGridRow selectedCellRow = depObj as DataGridRow;
        if (FindRowIndex(selectedCellRow) == maindg.Items.Count - 1)
        {
            if (Here I want to check if cell's value is null or empty)
            {
                btnSave.Focus();
                return;
            }
        }
    }
}

我在谷歌上搜索了这个问题。但每次我都能得到所选单元格的值。假设我想找到一个单元格的值它属于第5行第4列，那么我怎么找到它?

获取DataGrid中特定单元格的值

您可以尝试下面的代码，它将为您提供单元格。

if (selectedCellRow != null)
{
    DataGridCellsPresenter presenter = GetVisualChild<DataGridCellsPresenter>(selectedCellRow);
    DataGridCell cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
    var cellValue = cell.Content;
}
