WPF Datagrid 将最后一行网格复制到网格中的新行（Devexpress）

Question

有件事我想做，但我堆成一个假人。这是步骤；

当用户在 Datagrid 上按下 ctrl + D 按钮时
datagrid 值的最后一行 将复制到 clippopard 或某处（eg.CopyToClipboard 函数）
从剪贴板或其他东西到再次它可能是一个函数，例如pastToclipboard 或者我们可以使用 InitNewRowEventArgs 它让我们可以访问 RowHandle 函数

这是我到目前为止完成的代码。

private void dtg_tabletrial_KeyDown(object sender, KeyEventArgs e)
 {
  if (e.Key == Key.D && (Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
        {  
          MessageBox.Show("You hit ctrl + D");
        }
 }

 private void dtg_view_InitNewRow(object sender, DevExpress.Xpf.Grid.InitNewRowEventArgs e)
    {
        dtg_tabletrial.SetCellValue(e.RowHandle, "UserName", "emre");
        dtg_tabletrial.SetCellValue(e.RowHandle, "Surname", "newcompany");
        dtg_tabletrial.SetCellValue(e.RowHandle, "Address", "new addres");
        dtg_tabletrial.SetCellValue(e.RowHandle, "Phone", "new phone");   
    }

我假设 'last row' 表示由当前应用的排序和过滤确定的最后 visible 行（即，当您滚动到底部，目前可能不在视图中。

有几种方法可以做到这一点，但这是最简单的（我认为），它不需要标记你的支持行对象 [Serializable]:

private void CopyLastRowToAnotherGrid()
{
    const int targetHandle = DataControlBase.NewItemRowHandle;

    GridControl source = /* your first grid */;
    GridControl target = /* your second grid */;

    if (source.VisibleRowCount < 1|| !target.IsValidRowHandle(targetHandle))
        return;

    var sourceHandle = source.GetRowHandleByVisibleIndex(source.VisibleRowCount - 1);

    // You can set ClipboardCopyMode in Xaml.  The point is, we want the
    // headers to be included so we can match the cells up in case the
    // user has reordered them.
    source.ClipboardCopyMode = ClipboardCopyMode.IncludeHeader;

    source.CopyRowsToClipboard(new[] { sourceHandle });

    var clipboardData = Clipboard.GetDataObject();

    var data = clipboardData?.GetData(DataFormats.Text) as string;
    if (data == null)
        return;

    var targetView = target.View as TableView;
    if (targetView == null)
        return;

    targetView.AddNewRow();

    var headersAndRows = data.Split('\n');
    var headers = headersAndRows[0].Split('\t');
    var columnValues = headersAndRows[1].Split('\t');
    var columnLookup = target.Columns.ToDictionary(o => o.HeaderCaption?.ToString());

    for (var i = 0; i < headers.Length; i++)
    {
        var header = headers[i];
        if (columnLookup.TryGetValue(header, out var column))
            target.SetCellValue(targetHandle, column, columnValues[i]);
    }

    // If you want to *move* the row, then uncomment this line to
    // delete the row from the first grid:
    //(source.View as TableView)?.DeleteRow(sourceHandle);
}

再次感谢 Mike Strobel，但我还提供了另一个解决方案。我在这里写给需要它的人。

和平

 private void dtg_tabletrial_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.D && (Keyboard.Modifiers & ModifierKeys.Control) == ModifierKeys.Control)
        {

            DataGridTrialTable ff = new DataGridTrialTable();
            ff.Address = dtgtrialTable.LastOrDefault().Address;
            ff.UserName = dtgtrialTable.LastOrDefault().UserName;
            ff.Phone = dtgtrialTable.LastOrDefault().Phone;
            ff.Surname = dtgtrialTable.LastOrDefault().Surname;

            dtgtrialTable.Add(ff);
        }
    }
