webfrom 动态生成gridview添加按钮列后如何进入按钮的点击事件，求大神指教

Question

public void setBind(DataTable dt)
{
gvshow = new GridView();
gvshow.Width = Unit.Pixel(700);

        gvshow.AutoGenerateColumns = false;
        gvshow.RowEditing  += new GridViewEditEventHandler(gvshow_RowEditing); //添加编辑事件
       // gvshow.RowDeleting  += new GridViewDeleteEventHandler(gvshow_RowDeleting);
        gvshow.DataSource = dt;
        for (int i = 0; i < dt.Columns.Count; i++)
        {
            BoundField bc = new BoundField();
            bc.DataField = dt.Columns[i].ColumnName.ToString();
            bc.HeaderText = dt.Columns[i].Caption.ToString();
            gvshow.Columns.Add(bc);
        }


        CommandField cf = new CommandField();
        cf.ButtonType = ButtonType.Button;
        cf.HeaderText = "添加规格";
        cf.EditText = "添加规格";
        cf.ShowEditButton = true;
        cf.CausesValidation = false;
        cf.ItemStyle.HorizontalAlign = HorizontalAlign.Center;
        gvshow.Columns.Add(cf);

        CommandField cf2 = new CommandField();
        cf2.ButtonType = ButtonType.Button;
        cf2.HeaderText = "chakan";
        cf2.SelectText = "chakan";
        cf2.ShowSelectButton = true;
        cf2.CausesValidation = false;
        gvshow.Columns.Add(cf2);
        gvshow.DataBind();
        divshow.Controls.Add(gvshow);

    }

            这个是生成gv的代码，和添加按钮列的代码

             public  void gvshow_RowEditing(object sender, GridViewEditEventArgs e)
    {
        int i = e.NewEditIndex;

        string id = gvshow.Rows[i].Cells[0].Text.ToString();
        ShowMessageBox(i.ToString()+id);
    }
            我点击编辑按钮一直进不去这个事件
