Question

我在查找DataGrid中刚编辑过的单元格的行和单元索引时遇到问题。我正在使用CellEditEnding事件来了解单元格的编辑时间。

直到现在我已经设法做了这样的事情。 Col1包含属性DisplayIndex，这是所选列的索引，但我找不到相同的方式。

    private void DataGridData_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
    {
        DataGridColumn col1 = e.Column;
        DataGridRow row1 = e.Row;
    }

Answer 1

我现在已经开始工作了。这就是它的样子：

private void DataGridData_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
    {
        DataGridColumn col1 = e.Column;
        DataGridRow row1 = e.Row;
        int row_index = ((DataGrid)sender).ItemContainerGenerator.IndexFromContainer(row1);
        int col_index = col1.DisplayIndex;
    }

迟到的答案，但对于发现此问题的任何人来说，此代码都可以通过将此事件添加到您的数据网格来实现：

private void dgMAQ_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
    {
DependencyObject dep = (DependencyObject)e.EditingElement;
            string newText = string.Empty;

        //Check if the item being edited is a textbox
        if (dep is TextBox)
        {
            TextBox txt = dep as TextBox;
            if (txt.Text != "")
            {
                newText = txt.Text;
            }
            else
            {
                newText = string.Empty;
            }
        }
        //New text is the new text that has been entered into the cell

       //Check that the value is what you want it to be
        double isDouble = 0;
        if (double.TryParse(newText, out isDouble) == true)
        {

            while ((dep != null) && !(dep is DataGridCell))
            {
                dep = VisualTreeHelper.GetParent(dep);
            }

            if (dep == null)
                return;


            if (dep is DataGridCell)
            {
                DataGridCell cell = dep as DataGridCell;

                // navigate further up the tree
                while ((dep != null) && !(dep is DataGridRow))
                {
                    dep = VisualTreeHelper.GetParent(dep);
                }

                if (dep == null)
                    return;

                DataGridRow row = dep as DataGridRow;
                int rowIndex = row.GetIndex();

                int columnIndex = cell.Column.DisplayIndex;

        //Check the column index. Possibly different save options for different columns
                if (columnIndex == 3)
                {

                    if (newText != string.Empty)
                    {
                        //Do what you want with newtext
                    }
                }
}

要获取没有'sender'参数的行索引，您可以尝试：

 Convert.ToInt32(e.Row.Header)

结合Patryk答案的缩写形式，给出了：

 private void DataGridData_CellEditEnding(DataGridCellEditEndingEventArgs e)
    {
        int col1 = e.Column.DisplayIndex;
        int row1 = Convert.ToInt32(e.Row.Header);
    }
