Need to Set the Session Variable

I need to store session information.

private void LogError(SqlConnection pconStockSelect)
// Collects error information and saves it in the errors table.
{
strErrMessage = Session["Message"].ToString();

error: the Session variable is null.

How do I set the Session variable?

Thanks,

Om Prakash

if ( Session["Message"] != null )
{
string errmsg = Session["Message"];
// do other stuff
}

You set a session like so
Session["session_name"] = "Text";

But that's got nothing to do with the code you posted

The ShowError page is opened when an exception is triggered.

I have try/catch blocks in several places.

The exception that opened this page is not handled.

I need to see a stack trace to find out where the exception occurred.

The exception is somewhere in this code that attempts to set up a site map.

The bug was removed when I removed this code from the master page:

<tr id="rowSiteMap">
<td colspan="2" style="width: auto; height: 24px;
font-family: Arial, Helvetica, sans-serif; font-size: 12px; font-weight: normal; font-style: normal;
font-variant: normal; border: thin solid #0000FF;
color: #0000FF; background-color: #FFFFCC; text-align: left;">

<asp:SiteMapPath ID="SiteMapPath1" runat="server" Width="65%" Font-Size="12pt">

<PathSeparatorTemplate>
<asp:Image ID="Image1" ImageUrl="~/Images/arrowright.gif" runat="server" />
</PathSeparatorTemplate>

<RootNodeTemplate>
You are here 
</RootNodeTemplate>

<CurrentNodeTemplate>
<%# Eval("title") %>
  
<%# Eval("description") %>
</CurrentNodeTemplate>

</asp:SiteMapPath>
</td>
</tr>

Could you recommend a document that shows how to set up the site map?

I would also like to know how I can get exception information when I have no idea where the exception came from.

This is the web.config statement that directs exceptions to the exception details page.

<customErrors mode="On" defaultRedirect="~/ErrorHandling/ShowError.aspx">
</customErrors>

Thanks,
