【在线】GridView中添加了一个按钮，单击该按钮时怎样获得对应行的个项值？

GridView中添加了一个按钮，单击该按钮时怎样获得对应行的各项值？比如第一列

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Display")
        {
            DataRow isplay_Row = ((DataRow)((Button)e.CommandSource).Parent.Parent);
        }
    }所在行的按钮的父控件的父控件按钮->单元格->行

只要取出同行的值就行了，比如取出第二行，字段为name的值
怎么取？

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Display")
        {
            DataRow isplay_Row = ((DataRow)((Button)e.CommandSource).Parent.Parent);
            isplay_Row["name"].ToString();
        }     }当前行name字段

出现错误，无法将...Control转换为DataRow

//我是新手,不知对不对
    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        int liRow;
        string lsField;
        if (e.CommandName == "ShowDetail")
        {
            liRow= Convert.ToInt32(e.CommandArgument);
            lsField = GridView1.Rows[liRow].Cells[3].Text;

        }
    }

    {
        if (!this.IsPostBack)
        {
            GridBind();
        }
    }    public void GridBind()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add(new DataColumn("数字", typeof(int)));
        dt.Columns.Add(new DataColumn("平方", typeof(int)));
        dt.Columns.Add(new DataColumn("立方", typeof(int)));        DataRow dr;        for (int count = 1; count <= 10; count++)
        {
            dr = dt.NewRow();
            dr[0] = count;
            dr[1] = count * count;
            dr[2] = count * count * count;
            dt.Rows.Add(dr);
        }        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Display")
        {
            GridViewRow isplay_Row = (GridViewRow)((Button)e.CommandSource).Parent.Parent;
            string select1 = ((Label)isplay_Row.FindControl("数字")).Text;//数字
            string select2 = ((Label)isplay_Row.FindControl("平方")).Text;//平方
            string select3 = ((Label)isplay_Row.FindControl("立方")).Text;//立方
        }       }
}

我用GridView1_SelectedIndexChanged实现了，但不喜欢这样

gdstx 的写法也对，不过要在绑定事件中给button加参数  protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ((Button)e.Row.FindControl("Button1")).CommandArgument = e.Row.RowIndex.ToString();
        }
    }
