推荐答案

我希望您使用数据列表显示项目

这意味着linkbutton必须在数据列表控件中，就像下面的

Hi,

I hopw you are using datalist for displaying items

that means linkbutton must in datalist control so just like below

<asp:linkbutton id="fgdfg" runat="server" commandname="viewdet" commandargument="<%#Eval("itemid")" xmlns:asp="#unknown">View Details</asp:linkbutton>

之后，您必须使用datalist的itemcommand处理该linkbutton事件.

After that you''ve to handle that linkbutton event by using itemcommand of datalist

//under itemcommand event of datalist
if(e.commandname=="viewdet")
{
   response.redirect("viewdetails.aspx?itemid="+e.commandargument.tostring());
}

通过使用上面的代码，您可以将该项目ID发送到viewdetails aspx页面

在该页面中，您可以在pageload中检索有关该查询字符串的数据
并在详细视图中显示

我希望你能理解我说的话

最好的

By using above code you can send that item id to viewdetails aspx page

in that page you can retrieve data regarding that querystring in pageload
and display it in detailed view

I hopw you understood What I said

All the Best

2) Session is handle to store big amount of data so in your case if you create a data table in your memory for storing items which is user added to its selection and then directly you can add that data table to your session and use in your other page by converting session to data table like this....

//In Your Item Selection Page that is Items.aspx
Session["MyDataTable"] = dt;
Response.Redirect("~/ItemSelectionView.aspx");
//and then use it for displaying item in ItemSelectionView.aspx page
DataTable dt = (DataTable)Session["MyDataTable"];
//then use dt as your display control's datasource..... like this...
GridView1.DataSource = dt;
GridView1.DataBinding();
