Answer 1

If you are indeed clicking a hyperlink which redirects to another page, you cannot get that information.

The only way to do it would be to include the information you need in a querystring, and parse the querystring on the next page.

However, if you are posting the form to another page, and your hyperlink is actually an input, your information will be available in the post data.

If your hyperlink is actually a server control, there are many possibilities.

It might help to see some code.

OK, if this is your code:

<td> 
    <asp:Hyperlink ID="NameLabel" runat="server" Text='<%# Eval("Name") %>' NavigateUrl="~/anotherpage.aspx"/> 
</td>

There are a few things you can do. First, you can change your asp:Hyperlink to an asp:LinkButton add a click event and remove the NavigateUrl property:

<td> 
    <asp:LinkButton ID="NameLabel" runat="server" Text='<%# Eval("Name") %>' OnClick="NameLabel_Click"/> 
</td>    

Now, use the event handler to do what you need:

    //Use querystring
    protected void NameLabel_Click(object sender, EventArgs e)
    {
        var link = sender as LinkButton;
        Response.Redirect(String.Format("anotherpage.aspx?name={0}", link.Text));
    }

    //Use session
    protected void NameLabel_Click(object sender, EventArgs e)
    {
        var link = sender as LinkButton;
        Session["name"] = link.Text;
        Response.Redirect("anotherpage.aspx?");
    }

Then, in the Page_Load event of your landing page, you can do this:

//Session
var name = Session["name"];

//Querystring
var name = Request.QueryString["name"];
