我在gridView中添加了编辑列的触发事件，但是我要点击两遍“编辑”，单元格才处于可编辑状态。求教：如何点击一次“编辑”，就可以呈现编辑状态。

前台页面：

<sinopec:SmartGridView ID="gvList" runat="server" AllowSorting="True"
                        AutoGenerateColumns="False" CurrentSortDirection="Descending"
                        DataBindHandler="bindgvList" EmptyDataText="没有符合条件的数据" PagerBinding="pagerList"
                        SortButtonImageFold="~/Images/"  Width="100%" CurrentSortExpression="Pcode"
                        AllowPaging="True" onrowcancelingedit="gvList_RowCancelingEdit"
                        onrowediting="gvList_RowEditing" onrowupdating="gvList_RowUpdating">
      <Columns>
       <asp:BoundField DataField="TID" HeaderText="外键" SortExpression="TID"
                                Visible="false">
       </asp:BoundField>
       <asp:BoundField DataField="Manufacturerse" HeaderText="厂商"
                                SortExpression="Manufacturerse">
       </asp:BoundField>
       <asp:BoundField DataField="SolutionTime" HeaderText="平均解决时间"
                                SortExpression="SolutionTime">
       </asp:BoundField>
       <asp:BoundField DataField="QuestionNum" HeaderText="问题数量"
                                SortExpression="QuestionNum">
       </asp:BoundField>
       <asp:CommandField HeaderText="编辑" ShowEditButton="True" />
      </Columns>
     </sinopec:SmartGridView>

后台代码：

protected void gvList_RowEditing(object sender, GridViewEditEventArgs e)
    {
      this.gvList.EditIndex = e.NewEditIndex;

    }
