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

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

这个问题我跪了一天了，按照网上的方法我也看了，没什么区别，就是进不去这个按钮的点击事件

这里应该是给按钮的Click事件添加事件呀，而且你添加的事件是行编辑事件，是在编辑行内数据的时候触发的事件而不是点击按钮的时候触发的事件呀
