关于GridView绑定后事件RowDataBound 方法改怎么写顺便解释一下

[y13550297325]

GridView绑定后事件RowDataBound 先绑定里面有一个TypeId，在执行玩绑定后 我想把这个TypeID 修改为 另一个表中的TypeName
网页:
<asp:GridView ID="GridView1" runat="server" Width="860px" AutoGenerateColumns="False" onrowdatabound="GridView1_RowDataBound" >
<asp:BoundField DataField="TypeId" HeaderText="所属类别"/>
</asp:GridView>

.CS:
/// <summary>
/// 在绑定后对行进行绑定
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

int Id =Convert.ToInt32(e.Row.Cells[1]);
string Type = productTypebll.GetProductTypeById(Id).Type;
e.Row.Cells[1].Text = Type;

}

      if (e.Row.RowType == DataControlRowType.DataRow)
      {
          e.Row.Cells[0].Text = "a";
      }

int Id =Convert.ToInt32(e.Row.Cells[1].Text);
