For various reasons I need  to set a session variable when clicking a hyperlink.  I know this is basic but I can't figure out what I'm doing wrong.

My code is below.  Any help if much appreciated.

My Function: 
<script language="VB" runat="server">
Sub setEventId(Source As Object, E As EventArgs)
    Session("eventId") = sp_EventDetail.FieldValue("eventId")
End Sub
My Link: 
<asp:HyperLink id="link1" NavigateUrl="test2.aspx" target='_self' OnClick="setEventId" runat="Server">Test</asp:HyperLink></ContentsTemplate>

Open in new window

What is sp_EventDetail?
Could you post all code?

Also, keep in mind that when you click that link, the page does a postback meaning that the page is reloaded, the page_load event is run and then your sub setEventId runs.

Hi and thanks for the reply.  

Attached is code for the entire page and here is a link to the page (sorry it's a bit of a mess).

Here's what I'm trying to do and maybe there's a better approach.  
The sp_EventDetail is a dataset (return by a stored procedure) that contains a list of calendar events.  These events are displayed in a table.  My "test" link is included with every row.  When clicked I want to set a session variable named eventId to the eventId of the row with the hyperlink.

The reason I'm not passing this in the URL is because of a strange situation.  The link will actually go to an .html page.  From the html page, the user will navigate to an aspx page.  When they get to that 2nd html page, I need access to the eventId associated with the calendar event they clicked two pages back.  I thought I could do this using a session variable.  Is there some other way?

Thanks again.

Try using a LinkButton instead of a Hyperlink. They will look exactly the same and you will be able to use the OnClick event of the LinkButton so you can add the Session variable.
