错误：双向绑定需要Path或XPath

Question

我的xaml代码：

<DataGrid x:Name="pRCPROFDataGrid"
                                              EnableRowVirtualization="True"
                                              ItemsSource="{Binding}"
                                              RowDetailsVisibilityMode="Visible"
                                              CanUserAddRows="True"
                                              FlowDirection="RightToLeft" RowEditEnding="pRCPROFDataGrid_RowEditEnding"/>

我的代码c＃：

DataTable tbl = lib.GetDataFromTable("SELECT column_name, data_type, nullable FROM user_tab_columns WHERE table_name = '" + _table + "' order by column_id", "Usr");
        DataTable sourceTable = new DataTable();
        string[] _label = lib.GetDetailsTable(_table);

for (int element = 0; element <= tbl.Rows.Count - 1; element++)
        {
            DataGridBoundColumn _xtemp = null;
            if (tbl.Rows[element][1].ToString() == "bit")
            {
                _xtemp = new DataGridCheckBoxColumn();
            }
            else
            {
                _xtemp = new DataGridTextColumn();
            }

            _xtemp.Header = _label[element];
            _xtemp.Binding = new Binding(tbl.Rows[element][0].ToString());
            _grid.Columns.Add(_xtemp);
            if (element == 0)
                _xtemp.Visibility = Visibility.Hidden;
            if (element == 1)
                _xtemp.Width = new DataGridLength(1,    DataGridLengthUnitType.Star);
        }

_grid.ItemsSource = sourceTable.DefaultView;

结果：

附加信息：双向绑定需要Path或XPath。

System.InvalidOperationException未处理 消息：未知模块中发生未处理的“System.InvalidOperationException”类型异常。 附加信息：双向绑定需要Path或XPath。

通过从列标题（名称）中删除斜杠解决了同样的问题。
