Ahhh. I would just use a button and handle the Session check in the click event handler. Here is how I would do it with a link button:

asp Code:

<asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">LinkButton</asp:LinkButton>

Then the click event handler:

csharp Code:

protected void LinkButton1_Click(object sender, EventArgs e)
    {
         //Check for session
    }

Now it is pretty obvious that you are a beginner to .NET so might I suggest Imar's new book: http://www.amazon.com/Beginning-ASP-...dp/0470502215/ Imar is an amazing author and his work is spot on.

i was aware about the button link but i do not wana use the server control. my requirement was to do something with <a> </a>. any help with this one.

If your requirment is to use a plain HTML anchor tag and NO javascript you are simply out of luck unless you go back to a classic ASP type model where you post from one page to another but that seems a bit overkill IMHO.

I am aware about IMAR . he is a good author i have been following his blog.
so do u think if i buy ASP.NET 4 will it cover all basic stuff from 2.0 n 3.5

The .NET 4.0 books are going to focus mostly on what is new in 4.0; while some of this material would be backwards compatiable with 2.0 and 3.x things like the TPL and changes to the language would not (obviously). Below are the 2.0 and 3.5 versions of this book.
