WPF 遍历 DataGrid 每行的控件

           下面两种语法，只是变相的形式而已。

 　　　　for (int i = 0; i < dgETL.Items.Count; i++)
            {
                CheckBox selectCheckBoxInCell = dgETL.Columns[0].GetCellContent(dgETL.Items[i]) as CheckBox;
                if (selectCheckBoxInCell != null)
                {
                    selectCheckBoxInCell.IsChecked = cbxOne.IsChecked;
                }
            }

            foreach (var item in dgETL.Items)
            {
                CheckBox selectCheckBoxInCell = dgETL.Columns[0].GetCellContent(item) as CheckBox;
                if (selectCheckBoxInCell != null)
                {
                    selectCheckBoxInCell.IsChecked = cbxOne.IsChecked;
                }
            }
