repeater传参解决办法

repeater传参
<a href='followvisitAdd.aspx?Id=<%#Eval("contentid") %>&followupcontent=<%#Eval("Followupcontent") %>&followupresult=<%#Eval("Followupresults") %>'><asp:Label ID="update" runat="server" Text="修改"></asp:Label></a>

int conid = Utils.GetQueryInt("contentid");
  string follcon = Utils.GetQueryString("followupcontent");
  string follres = Utils.GetQueryString("followupresults");
  Updfollowup(conid,follcon,follres);


我想从上面连接中传到后台参数，然后填充textbox，然后点击按钮进行修改功能，不知道怎么把传过来的数据填充到textbox中，并传到方法中


------解决方案--------------------------------------------------------
string aaa=Request["Id"].ToString();
string bbb=Request["followupcontent"].ToString();
string ccc=Request["followupresult"].ToString();
......

------解决方案--------------------------------------------------------
if (this.txtcontant.Text.Trim() != "" || this.txtresults.Text.Trim() != "")
{
int conid = Utils.GetQueryInt("contentid");
this.txtcontant.Text = Request["followupcontent"].ToString();
this.txtresults.Text = Request["followupresults"].ToString();
string follcon = txtcontant.Text;
string follres = txtresults.Text;
Updfollowup(conid,follcon,follres);
