C#Datatable的绑定，编辑，提交等相关应用

bind_Member.EndEdit()----将编辑由控件提交到后台的datatable

RowState ---已经行的不同状态进行不同的后台处理，新增、修改、删除

            dataTable = bind_Member.DataSource as DataTable;
            if (dataTable.GetChanges() == null)
            { return; }
            foreach (DataRow item in dataTable.GetChanges().Rows)
            {
                if (item.RowState == DataRowState.Added)
                {
                    this.Text += "new-" + item[3, DataRowVersion.Current].ToString();
                }
                else if (item.RowState == DataRowState.Modified)
                { this.Text += "edit-" + item[3, DataRowVersion.Original].ToString() + "--" + item[3, DataRowVersion.Current].ToString(); }
                else if (item.RowState == DataRowState.Deleted)
                { this.Text += "delete-" + item[3, DataRowVersion.Original].ToString(); }
            }
            //dataTable.RejectChanges();//放弃修改
            dataTable.AcceptChanges();//提交修改
