ASP.net - Get ID from URL

Question

I have a datalist and I'm sending the user ID of the user through the URL to another page:

<asp:HyperLink ID="LastNameLabel" runat="server" Text='<%# Eval("LastName") %>' NavigateUrl='<%# FormatUrl( (int) Eval("FriendsAccountID")) %>' />

and the function:

protected string FormatUrl(int FriendsAccountID)
{
    return "WebForm3.aspx?" + FriendsAccountID;
}

---

This works but I'm kind of a noobie and I'm not sure how get the ID once I'm on the next page. Any ideas?

Solution

Change your code to this:

protected string FormatUrl(int FriendsAccountID) { return "WebForm3.aspx?UserID=" + FriendsAccountID; }

Then you can access the UserID like this:

Request.QueryString["UserID"];

Here is a link to QueryString on MSDN.

Can that go straight into the page load WebForm3?

Yes. Every Webform has access to the Request object.
