Linkbutton Text From Previouspage - asp.net

Question

I have a gridview with a linkbutton that is posting crosspage when a value in the ID column is clicked. I want the ID to be posted to the next page so that it cant be seen in the url. (no querystring) The gridview is contained within a contentplaceholder. I would like to know how to response.write the linkbuttons (lbID) text on details.aspx using findcontrol. Please help. (Im using VB, I should have mentioned that.)
<asp:Content ID="content" ContentPlaceHolderID="content" runat="server">
<asp:GridView ID="gvOpen" runat="server" AutoGenerateColumns="False"
BackColor="White" BorderColor="Black" BorderStyle="None" BorderWidth="1px"
CellPadding="4"
ForeColor="Black" Width="96%" DataKeyNames="id"
DataSourceID="Open" CssClass="Grid" AllowPaging="True">
<AlternatingRowStyle BackColor="#CCFFCC" />
<Columns>
<asp:ImageField DataImageUrlField="priority" HeaderText="Priority">
<ItemStyle Height="28px" HorizontalAlign="Center" VerticalAlign="Middle" Width="28px" />
</asp:ImageField>
<asp:TemplateField HeaderText="ID">
<ItemTemplate>
<asp:LinkButton ID="lbID" runat="server" PostBackUrl="~/details.aspx"> <%# Eval("ID") %></asp:LinkButton>
</ItemTemplate>

Answer 1

I think this is what you want: PostBackUrl
void Page_Load(object sender, EventArgs e)
{
LinkButton lbID = (LinkButton) PreviousPage.FindControl("lbID");
string linkText = "";
if(lbID != null)
linkText = lbID.Text;
}
You might want to set linkButton text like this
<asp:LinkButton ID="lbID" runat="server" PostBackUrl="~/details.aspx" Text='<%# Eval("ID") %>'></asp:LinkButton>
