Question

I’ve a grid view at FriendsList.aspx. Through this grid view, I will be able to see all the friends that I have. I can then navigate to FriendsDetails.aspx to view the details of a particular friend.

I can pass data from FriendsList.aspx to FriendsDetails.aspx.
However, I was unsure of how to use the passed value from FriendList.aspx.

Someone please enlighten me as to how can I go about doing this.

The code of my ItemTemplate. (I retrieve my data from a sql datasource)

<ItemTemplate>
    <asp:HyperLink 
          ID="HyperLink1" 
          runat="server" 
          Text="View friend's profile"
          NavigateUrl='<%# String.Format("~/FriendsList.aspx?FriendID={0}", Eval("FriendID")) %>'>
    </asp:HyperLink>
</ItemTemplate>

Answer 1

pull friendid from the request in the page.load handler and query the database

page_load(object sender, EventArgs e)
{
    var friendid = Request["FriendID"];
    var friend = getfriendfromdatabase(friendid);
    //use friend to load the controls.
}
